This review presents the first combined systematic and bibliometric review synthesising artificial intelligence (AI)-driven approaches to risk management in biogas production within wastewater treatment plants (WWTPs), with emphasis on decision-optimisation and operational safety. Seven academic databases: Scopus, Web of Science, IEEE Xplore, ScienceDirect, SpringerLink, Taylor & Francis, and Google Scholar were systematically searched from 2015 to March 2025, and screening followed PRISMA 2020 guidelines. Of 3,716 retrieved records, 109 studies met the inclusion criteria. Bibliometric mapping (VOSviewer) and qualitative synthesis identified five thematic clusters: (i) biogas process safety, (ii) IoT integration and renewable-energy, (iii) optimisation and supply-chain resilience, (iv) AI-driven decision-support frameworks, and (v) advanced machine-learning techniques. The analysis reveals a marked increase in publications since 2020, reflecting a shift from conceptual modelling toward applied digital risk solutions. Europe and China remain leading contributors, although collaboration networks are fragmented and methodological heterogeneity persists. Full-scale validation of AI models in operational WWTP-based biogas plants remains limited, with most studies relying on laboratory experiments, simulations, or pilot-scale data. Constraints include publication bias, database coverage, English-language restrictions, inconsistent performance metrics, and limited access to long-term Supervisory Control and Data Acquisition (SCADA) Systems datasets. The review demonstrates that AI-driven methods have significant potential to improve safety, operational efficiency, and regulatory assurance in biogas facilities. However, achieving practical and scalable implementation will require rigorous multi-site validation, standardised evaluation indicators, integration of explainable AI, and alignment with plant-level risk-governance frameworks.
这篇综述提出了第一个综合系统和文献计量学综述,综合了人工智能(AI)驱动的方法来管理废水处理厂(WWTPs)内沼气生产的风险,重点是决策优化和操作安全。从2015年到2025年3月,系统检索了Scopus、Web of Science、IEEE explore、ScienceDirect、SpringerLink、Taylor & Francis和b谷歌Scholar 7个学术数据库,筛选遵循PRISMA 2020指南。在3716份检索记录中,109项研究符合纳入标准。文献计量制图(VOSviewer)和定性综合确定了五个专题集群:(i)沼气过程安全,(ii)物联网集成和可再生能源,(iii)优化和供应链弹性,(iv)人工智能驱动的决策支持框架,以及(v)先进的机器学习技术。分析显示,自2020年以来,出版物显著增加,反映了从概念建模向应用数字风险解决方案的转变。欧洲和中国仍然是主要的贡献者,尽管合作网络是分散的,方法上的异质性仍然存在。人工智能模型在运营的基于污水处理厂的沼气厂中的全面验证仍然有限,大多数研究依赖于实验室实验、模拟或中试规模的数据。限制因素包括发表偏倚、数据库覆盖范围、英语语言限制、不一致的性能指标以及对长期监督控制和数据采集(SCADA)系统数据集的有限访问。该评估表明,人工智能驱动的方法在提高沼气设施的安全性、运营效率和监管保障方面具有巨大的潜力。然而,实现实际和可扩展的实施将需要严格的多站点验证、标准化的评估指标、可解释的人工智能的集成以及与工厂级风险治理框架的一致性。

Accurate and operative monitoring of municipal solid waste (MSW) landfills is critical for operational safety, spatial planning, and regulatory compliance. Traditional point-based surveying methods are precise, but they are limited in spatial density coverage and hence, efficiency. The objective of the study is to evaluate the application of airborne laser scanning (ALS) for detecting volume changes at operational MSW landfill in the Czech Republic. Specifically, the study determines optimal spatial resolution of digital terrain model (DTM) from ALS for estimation of landfill volume, estimates uncertainties related to slope steepness and different vegetation cover affecting the accuracy of ALS-derived DTM, and formalizes and applies the method for detecting landfill volume changes using ALS. Two ALS datasets (10 points/m2) were collected in a five-month interval and processed at multiple spatial resolutions (0.3 m to 1.5 m). GPS reference points were measured for ALS data co-registration and to assess the accuracy of ALS-derived elevations. Positional errors and their propagation into elevation errors were quantified, and vegetation-induced uncertainties were considered. Results indicate that DTM resolutions of 0.3–0.8 m provide the most reliable estimates of volume change, especially in heterogeneous areas such as vegetated slopes. Differences in the standard deviation (SD) of elevation changes for selected areas at the landfill between the DTM resolution of 0.3 m and coarser resolutions were minimal for stable surfaces such as roads and compacted waste (0.01–0.02 m), but higher for vegetated areas, where the SD increased by up to 0.10 m due to surface roughness and variable laser penetration through the canopy. Comparison with independent GPS reference points showed that finer DTMs (0.3 and 0.5 m) reduced both bias and variability (mean differences ≤ 0.23 m, SD ≤ 0.24 m), whereas coarser DTMs (0.8 and 1.5 m) increased systematic errors due to surface smoothing and vegetation-induced misclassification. The findings recommend acquiring ALS data in early spring or late autumn, when vegetation cover is minimal and the influence of canopy on DTM accuracy is reduced. The study presents a novel workflow integrating ALS data with error modeling to improve landfill monitoring protocols. While the workflow was demonstrated on a specific site, it has potential for adaptation and application in other MSW landfills.
对城市固体废物(MSW)填埋场进行准确和有效的监测对于运营安全、空间规划和法规遵从性至关重要。传统的基于点的测量方法是精确的,但它们在空间密度覆盖上受到限制,因此效率也受到限制。该研究的目的是评估机载激光扫描(ALS)在捷克共和国运营的生活垃圾填埋场检测体积变化的应用。具体而言,研究确定了利用ALS提取的数字地形模型(DTM)估算垃圾填埋场体积的最佳空间分辨率,估算了影响ALS提取的DTM精度的坡度和不同植被覆盖等不确定性,并形式化了利用ALS检测垃圾填埋场体积变化的方法。每隔5个月采集2个ALS数据集(10个点/m2),并在0.3 m ~ 1.5 m的空间分辨率下进行处理。测量GPS参考点用于ALS数据共配准,并评估ALS衍生高程的准确性。对位置误差及其传播为高程误差进行了量化,并考虑了植被引起的不确定性。结果表明,0.3 ~ 0.8 m的DTM分辨率提供了最可靠的体积变化估计,特别是在植被覆盖的斜坡等非均匀区域。垃圾填埋场选定区域的高程变化的标准差(SD)在0.3 m的DTM分辨率与较粗分辨率之间的差异对于稳定的表面(如道路和压实的废物)(0.01-0.02 m)最小,但对于植被区域则较大,由于表面粗糙度和激光穿透冠层的变化,SD增加了0.10 m。与独立的GPS参考点相比,更细的dtm(0.3和0.5 m)降低了偏差和变异(平均差≤0.23 m, SD≤0.24 m),而更粗的dtm(0.8和1.5 m)由于表面平滑和植被引起的误分类而增加了系统误差。研究结果建议在初春或深秋采集ALS数据,此时植被覆盖最小,冠层对DTM精度的影响较小。该研究提出了一种将ALS数据与误差建模相结合的新工作流程,以改进垃圾填埋场监测方案。虽然工作流程是在一个特定的地点演示,但它有可能在其他城市固体废物堆填区进行调整和应用。

Heavy metals (HMs) contamination is an emerging environmental and public health issues in south Asian country like Bangladesh. HMs from various anthropogenic sources accumulate in the soil, are taken up by plants and entering our food chain, which causes health disorder. However, this study synthesizes updated data on heavy metals contamination in agricultural soils, water, sediments, and food crops across the major industrial areas of Bangladesh from 2010 to 2024. We found that the agricultural soils surrounding of the Dhaka city is highly contaminated with Mn, Zn, Cu, Pb, Cr, Ni, As, Cd. Heavy metals content in water from Buriganaga and Sytalokka river of Dhaka city was greater in compared to countryside river. Similarly, the plants growing near Dhaka city were highly contaminated with HMs (Zn, Mn, Cu, Pb, Ni, Cr), which were Oryza sativa and Amaranthus dubius. Furthermore, in case of sediments, Sytalokka river sediment followed by Buriganga were contained higher content of heavy metals like Cd, Pb, Ni, Zn, Cr and Cu in compared to the other rivers across the Bangladesh. However, different remediation strategies like application of organic amendments, phytoremediation, bioremediation are currently using across the Bangladesh to limit the plant uptake and food chain contamination. This synthesis will provide baseline information and first nationwide comparison of heavy metals data among the different regions of Bangladesh that can be used by policymakers for risk prioritization over the country. Furthermore, this study underscores the urgent need for policy interventions to mitigate heavy metal pollution and ensure sustainable food safety.
在孟加拉国等南亚国家,重金属污染是一个新兴的环境和公共卫生问题。来自各种人为来源的有机污染物在土壤中积累,被植物吸收并进入我们的食物链,从而导致健康失调。然而,本研究综合了2010年至2024年孟加拉国主要工业区农业土壤、水、沉积物和粮食作物中重金属污染的最新数据。研究发现,达喀市周边农业土壤中Mn、Zn、Cu、Pb、Cr、Ni、As、Cd污染严重,达喀市布里加纳加河和Sytalokka河水体重金属含量高于农村河流。同样,生长在达卡市附近的植物也受到重金属(Zn、Mn、Cu、Pb、Ni、Cr)的严重污染,即水稻和苋属植物。此外,在沉积物方面,与孟加拉国其他河流相比,Sytalokka河沉积物中Cd、Pb、Ni、Zn、Cr和Cu等重金属含量较高,其次是Buriganga河。然而,孟加拉国目前正在使用不同的修复策略,如应用有机改进剂、植物修复、生物修复,以限制植物吸收和食物链污染。这种综合将提供基线信息,并首次在全国范围内比较孟加拉国不同地区的重金属数据,决策者可以利用这些数据在全国范围内确定风险优先次序。此外,本研究强调亟须采取政策干预措施减轻重金属污染,确保可持续的食品安全。

Despite global recognition of the climate crisis, greenhouse gas emissions are projected to rise by 8.8 % by 2030, primarily due to inadequate planning, poor implementation, and insufficient financial support. While international initiatives such as the ’Waste to Zero’ coalition launched at the 28th Conference of the Parties to the UNFCCC (COP 28) highlight the urgency of advancing decarbonization and the circularity of waste systems, this review focuses on how artificial intelligence (AI) can accelerate that transformation. It systematically explores the role of AI in advancing waste management practices, with a focus on predictive analytics, route optimization, and machine learning-based material classification. Beyond summarizing existing approaches, it proposes a multilayer framework that connects data sensing, planning, sorting, and treatment within an adaptive lifecycle perspective. The review further examines existing gaps related to policy support, infrastructure readiness, data standardization, and scalability. While numerous studies demonstrate the potential of AI to improve operational efficiency and material recovery, real-world implementation remains limited by economic, regulatory, and technological barriers. To address these limitations, a strategic roadmap is presented, integrating technical innovation with governance and investment pathways to enhance implementation potential. By consolidating these insights, the study offers a comprehensive synthesis that clarifies how AI can strengthen circularity across the waste lifecycle and guide the sector toward scalable, evidence-based sustainability transitions.
尽管全球认识到气候危机,但预计到2030年温室气体排放量将增加8.8%,主要原因是规划不足、实施不力和资金支持不足。虽然在《联合国气候变化框架公约》第28次缔约方会议上发起的“零废物”联盟等国际倡议强调了推进脱碳和废物系统循环的紧迫性,但本审查侧重于人工智能(AI)如何加速这一转变。它系统地探讨了人工智能在推进废物管理实践中的作用,重点是预测分析、路线优化和基于机器学习的材料分类。除了总结现有方法之外,它还提出了一个多层框架,将数据感知、规划、分类和处理从自适应生命周期的角度联系起来。审查进一步检查了与政策支持、基础设施准备、数据标准化和可伸缩性相关的现有差距。虽然大量研究表明人工智能在提高运营效率和材料回收方面具有潜力,但现实世界的实施仍然受到经济、监管和技术障碍的限制。为了解决这些限制,提出了一个战略路线图,将技术创新与治理和投资途径相结合,以提高实施潜力。通过整合这些见解,该研究提供了一个全面的综合,阐明了人工智能如何在废物生命周期中加强循环,并指导该行业向可扩展的、以证据为基础的可持续性转型。

Biogas production within wastewater treatment plants (WWTPs) provides renewable energy recovery but also introduces complex process-safety challenges arising from the interplay of human, organisational, and technical factors. This study systematically evaluates how these dimensions interact to influence process-safety outcomes in UK wastewater-based biogas facilities, addressing a gap where prior safety research has largely prioritised the examination of technical and operational failures in the petrochemical and chemical sectors. A mixed-methods design was adopted, integrating a PRISMA-guided literature review, a structured national survey of industry professionals (n = 90), and analysis of historical incident reports (n = 63). Triangulated quantitative and qualitative data were examined using correlation and regression analyses to identify interdependencies among risk drivers. Findings reveal that gas-leak risk shows the strongest correlation with general site risks (r = 0.857, p < 0.001), followed by human and organisational factors (HOFs) (r = 0.768, p < 0.001) and process factors (r = 0.733, p < 0.001). The regression model (R2 = 0.754) confirms that site-level governance (e.g., maintenance discipline, leadership visibility, and resource sufficiency) exerts the greatest influence on incident probability. These findings demonstrate that technical safeguards alone are insufficient without robust organisational and behavioural integration within Process Safety Management Systems (PSMS). The study demonstrates that HOFs directly shape safety outcomes in WWTPs, presenting a novel empirical contribution to literature, emphasising predictive maintenance, competence-based training, proactive reporting, and AI-enabled monitoring within PSMS as enablers of safer and more sustainable biogas recovery in wastewater operations.
污水处理厂(WWTPs)内的沼气生产提供了可再生能源回收,但也引入了复杂的过程安全挑战,这些挑战是由人、组织和技术因素的相互作用引起的。本研究系统地评估了这些维度如何相互作用,影响英国基于废水的沼气设施的过程安全结果,解决了之前的安全研究在很大程度上优先检查石化和化学部门的技术和操作故障的空白。采用混合方法设计,整合了prisma引导的文献综述、行业专业人士的结构化全国调查(n = 90)和历史事件报告分析(n = 63)。三角测量的定量和定性数据使用相关性和回归分析来确定风险驱动因素之间的相互依赖关系。研究结果显示,气体泄漏风险与一般现场风险的相关性最强(r = 0.857, p < 0.001),其次是人和组织因素(hof) (r = 0.768, p < 0.001)和工艺因素(r = 0.733, p < 0.001)。回归模型(R2 = 0.754)证实,站点级治理(例如,维护纪律、领导可见性和资源充分性)对事件概率的影响最大。这些发现表明,如果在过程安全管理系统(PSMS)中没有强有力的组织和行为整合,仅靠技术保障是不够的。该研究表明,hof直接影响污水处理厂的安全结果,为文献提供了新的经验贡献,强调PSMS内的预测性维护、基于能力的培训、主动报告和人工智能监测,使废水处理中更安全、更可持续的沼气回收成为可能。

Using machine learning (ML) models, including Linear Regression (LR), Support Vector Regression (SVR), Long Short-Term Memory (LSTM), and Random Forest (RF), the research integrates critical patient-related variables, such as indoor and outdoor patient counts, surgeries, and deaths. Based on eight years of comprehensive data (2016–2023) from the medical colleges in Rajshahi, Bangladesh, the LR model showed the most reliable outcomes, achieving R2 values between 0.91 and 0.95 for all waste categories and outperforming others with mean absolute errors (MAE) as low as 1.39 kg for recyclable waste. Projections reveal a significant 50 % surge in general waste by 2030, reaching approximately 987.75 tons, while infectious waste will grow from 66.54 to 735.23 tons. Monte Carlo simulations quantified variability across waste categories, demonstrating fluctuations within ±5% of mean values, ensuring robustness. Finally, the research represents a novel policy recommendation for zero waste generation at the study location, which advocates for category-specific MW management strategies, aligning with Sustainable Development Goals (SDGs) 3 (Good Health and Well-being), 12 (Responsible Consumption and Production), and 13 (Climate Action). This work introduces a novel precedent for incorporating artificial intelligence into healthcare operations to attain zero waste generation while tackling public health and environmental issues. Thus, this work offers an innovative methodology that integrates machine learning to link patient data with waste generation, providing practical insights for resource optimization and operational planning.
本研究提出了一个强大的框架,用于准确预测医疗保健环境中的医疗废物(MW)产生,解决不断升级的环境和公共卫生问题。该研究使用机器学习(ML)模型,包括线性回归(LR)、支持向量回归(SVR)、长短期记忆(LSTM)和随机森林(RF),整合了与患者相关的关键变量,如室内和室外患者数量、手术和死亡。基于孟加拉国拉杰沙希医学院8年的综合数据(2016-2023年),LR模型显示了最可靠的结果,所有废物类别的R2值在0.91至0.95之间,可回收废物的平均绝对误差(MAE)低至1.39千克,优于其他类型。预测显示,到2030年,一般废物将大幅增加50%,达到约987.75吨,而感染性废物将从66.54吨增加到735.23吨。蒙特卡罗模拟量化了废物类别之间的可变性,表明波动在平均值的±5%以内,确保了稳健性。最后,该研究为研究地点的零废物产生提出了一项新的政策建议,该建议主张采用特定类别的兆瓦管理战略,与可持续发展目标(sdg) 3(良好健康和福祉)、12(负责任的消费和生产)和13(气候行动)保持一致。这项工作引入了一个新的先例,将人工智能纳入医疗保健业务,以实现零废物产生,同时解决公共卫生和环境问题。因此,这项工作提供了一种创新的方法,将机器学习与患者数据与废物产生联系起来,为资源优化和运营规划提供实用的见解。

In this research, a sustainable system to obtain bioethanol from Eichhornia crassipes biomass contaminated with total chromium was developed A phytoremediation system was applied in order to remove chromium from tannery wastewater, using the resulting biomass as raw material. The dry biomass (DS) was subjected to an optimized pretreatment using a Box–Behnken experimental design in which 45 treatments were evaluated. The structural changes in the biomass were characterized by SEM and FTIR. After this, hydrolysis with 3 % H2SO4 using a steam explosion was performed. Chromium retention was higher in roots (99.29 %), leaves and stems (94.14 %). Treatment using C0 = 1.56 % had the highest removal efficiency (R = 95.51 %), followed by 3.13 % (93.47 %). Regarding valorization, the bioethanol yield reached 71.35 % in relation to reducing sugars and 0.12 mL/g with respect to the initial biomass. These results confirm the feasibility of integrating phytoremediation with bioethanol production as a sustainable alternative for treating tannery effluents.
在本研究中,开发了一种可持续的系统,从被总铬污染的石竹生物质中提取生物乙醇,并采用植物修复系统,以得到的生物质为原料去除制革废水中的铬。采用Box-Behnken试验设计,对45个处理进行了优化预处理。利用扫描电镜(SEM)和红外光谱(FTIR)对生物量结构变化进行了表征。在此之后,用3% H2SO4蒸汽爆炸进行水解。铬在根(99.29%)、叶和茎(94.14%)中保留率较高。C0 = 1.56%处理的去除率最高(R = 95.51%),其次为3.13%(93.47%)。在增值方面,生物乙醇的产率相对于还原糖达到71.35%,相对于初始生物量达到0.12 mL/g。这些结果证实了将植物修复与生物乙醇生产结合起来作为处理制革废水的可持续替代方案的可行性。

Rapid urbanization in Ghana has intensified the challenges associated with municipal solid waste management, particularly in relation to open dumping and illegal disposal practices. This study investigates the drivers, patterns, and spatial distribution of informal waste disposal across six municipalities, across Accra and Kumasi, using a mixed-methods approach that integrates household surveys (n = 600), key informant interviews, and machine learning-based route optimization. Results reveal that over 60 % of households resort to informal dumping due to limited-service coverage, high collection costs, and socio-cultural perceptions of waste. The waste stream is predominantly organic, with compostable materials accounting for over 70 % of total waste generated. Engineering-oriented interventions such as community-scale composting, AI-enhanced collection routing, and participatory monitoring using geolocation tools are proposed to address these systemic inefficiencies. The findings underscore the need for decentralized, context-sensitive, and technology-supported waste governance models. Policy recommendations are offered to align local practices with circular economy principles and improve environmental health outcomes.
加纳的快速城市化加剧了与城市固体废物管理有关的挑战,特别是与露天倾倒和非法处置做法有关的挑战。本研究采用综合家庭调查(n = 600)、关键信息访谈和基于机器学习的路径优化的混合方法,调查了阿克拉和库马西六个城市的非正式废物处理的驱动因素、模式和空间分布。结果显示,由于服务覆盖面有限、收集成本高以及对废物的社会文化观念,超过60%的家庭采用非正式倾倒方式。废物流主要是有机的,可堆肥的材料占总废物的70%以上。提出了以工程为导向的干预措施,如社区规模的堆肥、人工智能增强的收集路线和使用地理定位工具的参与式监测,以解决这些系统性的低效率问题。研究结果强调,需要建立分散的、对环境敏感的、技术支持的废物治理模式。提出了政策建议,使地方做法符合循环经济原则,并改善环境卫生成果。

Biosolarization is an alternative to pesticides for soil pest management that can utilize food industry organic matter byproducts as soil amendments to create conditions conducive to pest suppression. Spent mushroom substrate (SMS) is the main byproduct of mushroom cultivation. New uses are needed for this waste stream as its production continues to increase. This study evaluated two types of SMS as sole amendments and as co-amendments with cover crop biomass for biosolarization. SMS consisted of rice bran with hardwood sawdust (BS SMS) and soybean hulls with oak sawdust (SO SMS). Cover crop biomass was a mix of Secale cereale and Trifolium incarnatum. Gas evolution, pH, biocidal organic acid (BOA) production, phytotoxicity, and soil nitrogen were tracked during and/or after simulated biosolarization. SMS and cover crop treatments were compared to rice bran-amended soil and unamended, solarized soil. Results indicate that SO SMS treatments can produce BOA concentrations and phytotoxic conditions comparable to rice bran-amended soil, with BOA content correlating to radish seed germination indices with a coefficient of determination of 0.683. The pH of treatments including cover crop biomass, whether as a sole or co-amendment, significantly decreased during biosolarization, but were higher than pH of rice bran controls. SO SMS and cover crop biomass as sole amendments significantly increased total nitrogen content compared to solarized soil (P < 0.05), likely due to the addition of nitrogen-containing organic matter, but not mineral nitrogen. These findings suggest that certain SMS compositions may be valuable amendments for agricultural pest control via biosolarization.
生物日光化是一种替代农药的土壤害虫治理方法,它可以利用食品工业的有机副产品作为土壤改良剂,创造有利于害虫抑制的条件。废蘑菇基质是蘑菇栽培的主要副产物。随着其产量的不断增加,需要对这种废物流进行新的利用。本研究评估了两种类型的SMS作为单独修正和与覆盖作物生物量共同修正的生物光化度。米糠与硬木锯末(BS SMS)和大豆壳与橡木锯末(SO SMS)组成。覆盖作物生物量为黑麦和红车轴草的混合生物量。在模拟生物光照期间和/或之后,跟踪了气体演化、pH、杀菌剂有机酸(BOA)的产生、植物毒性和土壤氮。SMS和覆盖作物处理与水稻膜改良土壤和未改良的土壤进行了比较。结果表明,SO - SMS处理能产生与水稻改良土壤相当的BOA浓度和植物毒性条件,BOA含量与萝卜种子萌发指标的相关系数为0.683。包括覆盖作物生物量在内的处理,无论是单独处理还是共处理,在生物光照过程中pH值都显著降低,但高于米糠对照。与盐碱化土壤相比,sosm和覆被作物生物量作为唯一的改良剂显著增加了全氮含量(P < 0.05),这可能是由于添加了含氮有机质,而不是无机氮。这些发现表明,某些SMS组合物可能是通过生物日光控制农业害虫的有价值的修正物。

Soil aggregates are important for aeration, microbial activity, root growth, and infiltration. Soil aggregation can vary depending on microbial activity, soil organic carbon (SOC), and soil management practices. However, the underlying drivers and mechanism of aggregation under different land-uses in southwest Bangladesh remain largely unknown. The objective of current study was to explore the underlying mechanism of aggregation in the soils of southwestern Bangladesh. In current study, soil samples were collected from three widely practiced rice-based land-uses (fallow–rice–fallow, fallow–rice–watermelon, and shrimp–rice–fallow) across the Khulna district of southwest Bangladesh. Results exhibited that the aggregate stability indicated by mean weight diameter (MWD) in fallow-rice-fallow and fallow-rice-watermelon were significantly greater than shrimp-rice-fallow land-use (P < 0.05). Microbial activity in fallow-rice-fallow land-use was 3 times higher than shrimp-rice-fallow land-use (P < 0.05). SOC was also higher in the fallow-rice-fallow and fallow-rice-watermelon land-uses than shrimp-rice-fallow land-use. Scanning electron microscopy and Fourier transform infrared spectroscopy results indicated aggregated morphological features and greater polysaccharides intensity in fallow–rice–fallow and fallow–rice–watermelon land-uses, respectively. A positive relationship was found between microbial biomass carbon (MBC) and MWD (r = 0.56; P < 0.01), and between SOC and MWD (r = 0.38; P < 0.05), indicating the dominant role of soil microbes in aggregation and the enhancement of SOC. Principal component analysis results also support the dominant role of MBC and SOC in aggregation and identified two distinct land-uses based on the soil properties. The study results demonstrate that microbial activity plays a key role in aggregation, enhancing the decomposition of agricultural waste and increasing SOC under investigated land-uses of southwest Bangladesh.
土壤团聚体对通气、微生物活动、根系生长和渗透都很重要。土壤聚集可以根据微生物活动、土壤有机碳(SOC)和土壤管理实践而变化。然而,孟加拉国西南部不同土地利用下的潜在驱动因素和聚集机制在很大程度上仍然未知。本研究的目的是探讨在孟加拉国西南部土壤聚集的潜在机制。在目前的研究中,从孟加拉国西南部库尔纳地区三种广泛采用的以水稻为基础的土地利用方式(休耕-水稻-休耕、休耕-水稻-西瓜和虾-水稻-休耕)收集了土壤样本。结果表明,以平均重径(MWD)为指标,休耕稻-休耕和休耕稻-西瓜土地利用的团聚体稳定性显著大于虾-稻-休耕(P < 0.05)。稻田-休耕地土壤微生物活性是虾-水稻-休耕地土壤微生物活性的3倍(P < 0.05)。休耕-稻-休耕和休耕-稻-西瓜土地利用的有机碳含量也高于虾-稻-休耕土地利用。扫描电镜和傅里叶变换红外光谱分析结果表明,在休耕-水稻-西瓜和休耕-水稻-西瓜土地利用中,多糖形态呈聚集特征,且多糖强度较大。微生物生物量碳(MBC)与MWD呈显著正相关(r = 0.56; P < 0.01),土壤有机碳(SOC)与MWD呈显著正相关(r = 0.38; P < 0.05),说明土壤微生物对土壤有机碳的聚集和增强起主导作用。主成分分析结果也支持MBC和有机碳在聚集性中的主导作用,并根据土壤性质确定了两种不同的土地利用方式。研究结果表明,微生物活动在孟加拉国西南部调查土地利用中对农业废弃物的聚集、分解和有机碳的增加起着关键作用。
