Cities are the core carriers and key positions to achieve the dual carbon goals. It is of great significance to explore whether promoting urbanization can improve carbon emission performance, which is of great significance to comprehensively promote the goal of carbon neutrality. Based on the panel data from 2006 to 2021, this paper analyzes the spatial autocorrelation of carbon emission performance per unit space and the impact mechanism of urbanization process on it. The fixed-effect model was further used to identify the influencing factors of spatial carbon emission performance. The results show that: 1) China’s carbon emission performance per unit space is declining year by year. 2) There is a strong positive spatial correlation and stable path dependence on the performance of carbon emissions per unit space in each region. 3) To a certain extent, increasing the level of urbanization will reduce the carbon emission performance per unit space. 4) The urbanization process has a spatial spillover effect on the carbon emission performance per unit space of surrounding provinces, and the spatial spillover effect of industrial structure and energy consumption structure is more obvious than that of economic level, population density and urbanization rate. Based on the conclusions, this paper puts forward specific policy suggestions to reduce the carbon emission performance per unit space to help the low-carbon development of cities.
城市是实现双碳目标的核心载体和关键阵地。探讨推进城镇化能否提高碳排放绩效,对全面推进碳中和目标具有重要意义。本文基于 2006 年至 2021 年的面板数据,分析了单位空间碳排放绩效的空间自相关性以及城镇化进程对其的影响机制。并进一步利用固定效应模型识别了空间碳排放绩效的影响因素。结果表明1)中国单位空间碳排放绩效逐年下降。2)各地区单位空间碳排放绩效存在较强的空间正相关性和稳定的路径依赖性。3)城市化水平的提高会在一定程度上降低单位面积碳排放绩效。4)城镇化进程对周边省份单位空间碳排放绩效具有空间溢出效应,产业结构和能源消费结构的空间溢出效应比经济水平、人口密度和城镇化率的空间溢出效应更为明显。基于以上结论,本文提出了降低单位空间碳排放绩效的具体政策建议,以助力城市低碳发展。

Green pesticide use, as a key means to reduce pesticide use, plays a crucial role in promoting environmental and food safety. However, the effectiveness of green pesticide use policies in China falls short of expectations. Existing research mainly examines the policy promotion issues of green pesticide use from a static and single-agent perspective. However, green pesticide use behavior is a dynamic process influenced by multiple factors, including the government, farmers, and consumers. This paper builds an evolutionary tripartite game model of the government, farmers, and consumers from the perspective of dynamic strategy evolution and explores the evolutionary conditions that affect the stability of the tripartite game strategy during green pesticide application. The results show that 1) through different partnership models, the government, farmers, and consumers can evolve to a stable state. 2) Keeping the government’s regulatory intensity in the market for green agricultural products within a reasonable range will help farmers apply green pesticides. 3) Users’ preference for high-quality vegetables will increase the market selling price of green products. 4) Maintaining the government’s ecological subsidies for green pesticides will help stimulate farmers’ enthusiasm for using green pesticides. Therefore, the government should appropriately strengthen ecological subsidies and market supervision, guide consumers’ green consumption behavior, and encourage farmers to use green pesticides.
绿色农药作为减少农药使用的重要手段,在促进环境和食品安全方面发挥着至关重要的作用。然而,中国绿色农药使用政策的效果却不尽如人意。现有研究主要从静态和单一主体的角度研究绿色农药使用的政策促进问题。然而,绿色农药使用行为是一个受政府、农民和消费者等多重因素影响的动态过程。本文从动态策略演化的角度出发,建立了政府、农民和消费者三方博弈演化模型,并探讨了影响绿色农药使用过程中三方博弈策略稳定性的演化条件。结果表明:1)通过不同的合作模式,政府、农民和消费者可以演化到稳定状态。2)将政府对绿色农产品市场的监管力度控制在合理范围内有助于农民施用绿色农药。3)用户对高品质蔬菜的偏好将提高绿色产品的市场售价。4)保持政府对绿色农药的生态补贴,有利于激发农民使用绿色农药的积极性。因此,政府应适当加强生态补贴和市场监管,引导消费者的绿色消费行为,鼓励农民使用绿色农药。

Eutrophication due to nitrogen (N) loss from sloping farmland has a high risk in the Three Gorges Reservoir. Biochar and vegetated filter strips (VFS) are used to control nutrient runoff and increase soil water-holding capacity, soil nutrient retention, and crop yield. However, surface biochar application has limited ability to control N loss, especially from sloping farmland.In this study, different widths of ridged biochar permeable reactive barrier (RB-PRB) with VFS were employed to intercept N loss in runoff from sloping farmland. Adsorption characteristics of biochar for nitrate and ammonium N were evaluated using isothermal and kinetic adsorption models before field experiments. N index values for ammonium (NH4+), nitrate (NO3−), dissolved N (DTN), particulate N (PN), and total N (TN) lost through runoff were monitored from April 2019 to January 2020.NO3− and NH4+ sorption on biochar was predominantly physical adsorption with a maximum capacity of 4.51 and 4.12 mg g-1, respectively. During the research period, the dominant transportation pathway of N loss involved dissolved total N movement through subsurface flow, which accounted for 65.55% of the total loss. TN loss for CK was 1954 g·hm-2, while RB-PRB and VFS decreased N loss from sloping farmland by 36.7%. The interception efficiency of RB-PRB was highest at 0.3 m width. VFS successfully intercepted particulate N and reduced it by 32.75%. In terms of soil nutrients, the RB-PRB and VFS interventions led to a substantial 41.69% increase in the TN content of the soil at a 0.4 m width.The findings suggest that biochar has a favorable adsorption effect on NH4+ and NO3−, an appropriate width of RB-PRB with VFS could effectively reduce nitrogen loss from sloping farmland. Simultaneously, it enhances the water and fertilizer retention capacity of sloping cropland soil; however, the long-term implications necessitate further validation.
三峡库区坡耕地氮(N)流失导致富营养化的风险很高。生物炭和植被过滤带(VFS)可用于控制养分径流,提高土壤持水能力、土壤养分保持率和作物产量。本研究采用不同宽度的脊状生物炭渗透反应屏障(RB-PRB)和植被过滤带(VFS)来拦截坡耕地径流中的氮流失。在田间试验之前,使用等温吸附模型和动力学吸附模型评估了生物炭对硝态氮和铵态氮的吸附特性。从 2019 年 4 月到 2020 年 1 月,监测了通过径流流失的铵(NH4+)、硝酸盐(NO3-)、溶解氮(DTN)、颗粒氮(PN)和总氮(TN)的氮指数值。NO3- 和 NH4+ 在生物炭上的吸附主要是物理吸附,最大吸附容量分别为 4.51 和 4.12 mg g-1。在研究期间,氮流失的主要运输途径是通过地下流动的溶解总氮运动,占总流失量的 65.55%。CK 的 TN 流失量为 1954 g-hm-2,而 RB-PRB 和 VFS 则使坡耕地的氮流失量减少了 36.7%。RB-PRB 的拦截效率在 0.3 米宽时最高。VFS 成功拦截了微粒氮,并将其减少了 32.75%。研究结果表明,生物炭对 NH4+ 和 NO3- 有良好的吸附作用,适当宽度的 RB-PRB 和 VFS 可有效减少坡耕地的氮流失。研究结果表明,生物炭对 NH4+ 和 NO3- 有良好的吸附作用,适当宽度的 RB-PRB 与 VFS 可有效减少坡耕地的氮流失,同时还能提高坡耕地土壤的保水保肥能力,但其长期影响还需要进一步验证。

Global climate change is considered one of the greatest environmental threats in the world. It is expected to significantly change the global hydrological cycle. The two main water cycle components, potential evapotranspiration (PET) and precipitation (P), are closely related to vegetation dynamics. In this study, the partial correlation analysis method was used to analyzed the relationship between Normalized Difference Vegetation Index (NDVI) and climate factors (PET and P) based on grid cells. PET was calculated by FAO-56 Penman–Monteith method. Moreover, we also investigated the NDVI and climate factors in different vegetation cover types. The results showed that grassland, forest and cropland in China were positively correlated with PET and P. The time scales of the maximum partial correlation coefficients between NDVI and PET of grassland vegetation were mostly longer than 5–6 months. These time scales were longer than the time scales related to P. The partial correlation coefficients between NDVI and PET, P of forest vegetation were higher in northern China, whereas the spatial distribution of related time scales was the opposite. The partial correlation coefficients between NDVI and PET, P of forest vegetation were higher in northern China. However, the spatial distribution of related time scales was the opposite. The correlations between NDVI and PET, P of cropland vegetation and the time scales related to PET had clear spatial heterogeneity. The time scale of the correlation between NDVI and P for cropland in the northern China was about 2 months. P had a strong influence on the growth of various types of vegetation in the study area, and grassland vegetation was affected by P over the shortest time scale. We compare and analyze the results of this study with other related studies. These results provide a reference for exploring the dynamic changes in different vegetation types and factors impacting them.
全球气候变化被认为是世界上最大的环境威胁之一。预计它将极大地改变全球水文循环。水循环的两个主要组成部分--潜在蒸散量(PET)和降水量(P)与植被动态密切相关。本研究采用偏相关分析方法,以网格单元为基础,分析归一化植被指数(NDVI)与气候因子(PET 和 P)之间的关系。PET 采用 FAO-56 Penman-Monteith 方法计算。此外,我们还研究了不同植被覆盖类型的 NDVI 和气候因子。结果表明,中国的草地、森林和耕地与 PET 和 P 呈正相关。森林植被的 NDVI 与 PET、P 的偏相关系数在华北地区较高,而相关时间尺度的空间分布则相反。华北地区森林植被的 NDVI 与 PET、P 的偏相关系数较高。然而,相关时间尺度的空间分布却相反。耕地植被 NDVI 与 PET、P 的相关系数以及与 PET 相关的时间尺度具有明显的空间异质性。华北地区耕地植被 NDVI 与 P 的相关时间尺度约为 2 个月。磷对研究区各类植被的生长影响较大,其中草地植被受磷影响的时间尺度最短。我们将本研究结果与其他相关研究结果进行了比较和分析。这些结果为探索不同植被类型的动态变化及其影响因素提供了参考。

The primary climatic parameter frequently scrutinized in water balance assessments for water utilization is precipitation. Given its considerable variability across locations and over time, it is imperative to rely on high-quality statistical information to facilitate accurate analyses. This study aims to refine the estimation of precipitation data by enhancing information obtained from freely accessible satellite sensors with data collected from established observation stations. Monthly precipitation data spanning from 2000 to 2015 were gathered from 24 stations. Three distinct methodologies were employed to adjust individual station data to address missing data. Consistency analysis and data refinement were conducted for stations requiring adjustments, utilizing graphical analysis and non-parametric statistical techniques. The satellite products under evaluation correspond to the IMERG v6 algorithm. Subsequently, statistical metrics were used to compare observed and estimated data. A correction coefficient was computed by aligning monthly means between observed and calculated data to mitigate random and systemic errors. The IMERG algorithm demonstrates proficiency in accounting for altitude and seasonal variations, with the adjustment significantly enhancing its performance under these conditions.
在水资源利用的水平衡评估中,降水量是经常审查的主要气候参数。由于降水量在不同地点和不同时间的变化很大,因此必须依靠高质量的统计信息才能进行准确的分析。本研究旨在通过加强从可免费获取的卫星传感器获得的信息和从现有观测站收集的数据,完善降水量数据的估算。从 24 个观测站收集了 2000 年至 2015 年的月降水量数据。研究采用了三种不同的方法来调整各个观测站的数据,以解决数据缺失的问题。利用图形分析和非参数统计技术,对需要调整的站点进行一致性分析和数据完善。评估中的卫星产品与 IMERG v6 算法相对应。随后,使用统计指标对观测数据和估计数据进行比较。通过调整观测数据和计算数据的月平均值,计算出校正系数,以减少随机误差和系统误差。IMERG 算法在考虑海拔高度和季节变化方面表现出色,在这些条件下进行调整后,其性能显著提高。

The IMERG algorithm demonstrates proficiency in accounting for altitude and seasonal variations, with the adjustment significantly enhancing its performance under these conditions.","PeriodicalId":509564,"journal":{"name":"Frontiers in Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141272487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impact of ecosystem conservation and restoration activities are rarely monitored from a global, multidimensional and multivariable perspective. Here we present an approach to quantify the environmental impact of landscape restoration using long-term and high-resolution satellite observations. For two restoration areas in Tanzania, we can likely attribute an increase in the amount of water retained by the soil (∼0.01 m³ m⁻³, ∼13% average increase), a soil temperature drop (∼-0.5°C) and an increase in surface greenness (∼50% average increase) in 3.5 years. These datasets illuminate the impact of restoration initiatives on the landscape and support the reporting of comprehensive metrics to donors and partners. Satellite observations from commercial providers and space agencies are now achieving the frequency, resolution, and accuracy that can allow for the effective evaluation of restoration activities.
生态系统保护和恢复活动的影响很少从全球、多维和多变量的角度进行监测。在此,我们介绍一种利用长期高分辨率卫星观测来量化景观恢复对环境影响的方法。对于坦桑尼亚的两个恢复区域,我们可以认为在 3.5 年内土壤保水量增加了(0.01 m³ m-³,平均增加 13%),土壤温度下降了(0.5°C),地表绿度增加了(平均增加 50%)。这些数据集阐明了恢复措施对景观的影响,并支持向捐助者和合作伙伴报告综合指标。目前,商业供应商和空间机构提供的卫星观测在频率、分辨率和精确度方面都已达到可对恢复活动进行有效评估的水平。
