Compacted Clay Liners (CCL) are designed to prevent environmental contamination in landfills. These layers are designed with low permeability soils, which are difficult to obtain. To this end, bentonite can be added. The objective of this work is to evaluate the reliability of factor analysis on the hydraulic performance of sand-bentonite mixtures. Two types of designs were used, with the variables controlled: compaction energy (CE), water content (U) and percentage of bentonite (B). Experimental layers were made to obtain water permeability (kw). The results showed that CE and B are, respectively, the factors that most influence permeability. The application of adequate energy promotes better accommodation of bentonite soil particles in the voids in the sand, which, when moistened, undergo an expansion process, reducing the voids in the layer. All of these parameters can be optimized by using a curvature design to obtain kW. Therefore, knowledge of CCL kw is essential to ensure the safety of the local environmental environment.
压实粘土衬垫（CCL）是为防止垃圾填埋场的环境污染而设计的。这些衬垫层采用难以获得的低渗透性土壤。为此，可以添加膨润土。这项工作的目的是评估因素分析对砂膨润土混合物水力性能的可靠性。采用了两种类型的设计，变量控制为：压实能（CE）、含水量（U）和膨润土百分比（B）。实验层获得了透水性（kw）。结果表明，CE 和 B 分别是对透水性影响最大的因素。充足的能量可促进膨润土颗粒更好地容纳在砂的空隙中，而砂在湿润后会发生膨胀过程，从而减少土层中的空隙。所有这些参数都可以通过曲率设计进行优化，以获得 kW。因此，了解 CCL kw 对于确保当地环境安全至关重要。

Despite great potential for arbuscular mycorrhizal fungi (AMF) in restoration of heavy metals (HMs) polluted lands, limited information is available about the arbuscular mycorrhizal (AM) symbiosis of naturally-occurring hyperaccumulators. A preliminary survey was conducted to investigate the AM symbiosis of Viola baoshanensis, a Cadmium (Cd) hyperaccumulator, growing at an abandoned mine. Shoot/root ratios of 1.78 for Cd, and 2.57 for zinc (Zn) indicate that these two metals were preferentially transported from roots to shoots, whereas the ratio of 0.32 for lead (Pb) shows that most Pb was stored in roots. High level of colonization was found in the roots of V. baoshanensis with relative mycorrhizal root length of 69.1%, relative arbuscular richness of 46.9% and relative vesicular richness of 1.7%. Fifteen AMF species were identified from the root zone soil of V. baoshanensis. The dominant AMF genus was Glomus, and the most abundant species were Glomus ambisporum and Claroideglomus etunicatum.

Recent research indicates that exposure to green space may have positive effects on the mental health of students, potentially mediated by factors such as environmental satisfaction and social cohesion. However, the specific impact of green space exposure on students’ mental health during the COVID-19 campus lockdowns unexplored. To investigate this relationship, a survey was conducted via social media among 346 current students residing on a locked-down campus, assessing their mental well-being, green space satisfaction, social environment satisfaction, subjective exposure and objective exposure to green space. A structural equation model (SEM) was employed to examine the relationships among various dimensions of green space exposure, satisfaction and students’ mental well-being. The findings indicate that subjective exposure to green space has a positive impact on mental well-being and indirectly through social environment satisfaction. Additionally, objective exposure could indirectly influence mental well-being through green space satisfaction and social environment satisfaction.

A common technique for assessing the overall water quality state of surface water and groundwater systems globally is the water quality index (WQI) method. The aim of the research is to use four machine learning classifier algorithms: Gradient boosting, Naive Bayes, Random Forest, and K-Nearest Neighbour to determine which model was most effective at forecasting the various water quality index and classes of the Albanian Shkumbini River. The analysis was performed on the data collected during a 4-year period, in six monitoring points, for nine parameters. The predictive accuracy of the models, XGBoost, Random Forest, K-Nearest Neighbour, and Naive Bayes, was determined to be 98.61%, 94.44%, 91.22%, and 94.45%, respectively. Notably, the XGBoost algorithm demonstrated superior performance in terms of F1 score, sensitivity, and prediction accuracy, the lowest errors during both learning (RMSE = 2.1, MSE = 9.8, MAE = 1.13) and evaluating (RMSE = 0.0, MSE = 0.01, MAE = 0.01) stages. The findings highlighted that Biochemical oxygen demand (BOD), Bicarbonate (HCO3), and Total Phosphor had the most positive impact on the Shkumbini River’s water quality. Additionally, a statistically significant, strong positive correlation (r = 0.85) was identified between BOD and WQI, emphasizing its crucial role in influencing water quality in the Shkumbini River.

The biophysical characteristics of the areas that can be seen while travelling on motorways have an impact on the perception of the landscape. Highways provide diverse landscape experiences to travellers according to their natural and cultural qualities. Especially coastal ways that combine with nature and the sea have a high potential for scenic attractiveness. This study aims to analyse the scenic attractiveness of coastal ways using GIS and RS techniques. Persembe-Bolaman coastal way in the Black Sea Region of Turkey was selected as a case study. Three road features and seven viewshed features that are assumed to affect landscape attractiveness on the Persembe-Bolaman coastal road were selected. The data set of these features was categorised into three clusters by k-means clustering, one of the unsupervised learning algorithms. The most attractive cluster in terms of scenic attractiveness was selected by determining the characteristics of the clusters. In conclusion, it was found that the scenic attractiveness was the highest in Cluster-1, which corresponds to 46.3% of the selected route.

This study is the first-ever attempt to relate the tools of development control like Floor Space Index (FSI/FAR), ground area covered by building footprints (BFs), and proportions/configurations of open areas, with their impact on the surface urban heat island (SUHI) which modulates the air temperatures. In the case of the Indian megacity Mumbai, statistical analysis of the land surface temperatures (LST) and its correlation with the selected development indicators, reveals that for an FSI increase of 1.0 to 1.8 the SUHI is found to be–2.5 °C less and when BFs reduced from 90% to 42% SUHI was also reduced by –2.5 °C. Highrise development with a large plot size is desirable whereas low-rise development with FSI 1.0 on small plot sizes exhibits the highest SUHI. Open spaces without vegetation do not reduce SUHI. The correlation of development regulations with SUHI intensity will help urban planners to make more informed decisions.

Methodological aspects of assessing harmful impacts on the natural environment are presented, aimed at determining the indicator of ecosystem stability. The use of such an indicator makes it possible to determine environmental changes as a result of anthropogenic activity, as well as to determine the significance of these changes. A system is presented that systematizes the variety of consequences of anthropogenic impact on CLS. A qualitative scale of reducing harmful anthropogenic impact is proposed. It is proposed to conduct assessment of the categories of significance of harmful effects and ecological risk on the basis of a comprehensive evaluation of impacts on individual storeys and subsystems in the compartment from different sources of influence, taking into account their magnitude and intensity. The corresponding scales, a way of complex formation, categories of impact significance have been developed; also, an example of constructing an environmental risk matrix has been presented.

Linpan has a long history of over 2,300 years and is a unique cultural landscape heritage of the Chengdu Plain derived from the Dujiangyan hydraulic engineering. As urbanization has gradually degraded the Linpan landscape over the past decades, the government is helping to revitalize the local countryside by preserving it. The purpose of this study was to understand the perceptions of Linpan indigenous villagers about its conservation and use, and to investigate the differences in their perceptions and the factors influencing them. The city of Dujiangyan, located at the source of the Dujiangyan Irrigation Area, was taken as the case study area, and a questionnaire survey and quantitative analysis were adopted. The study shows that Linpan indigenous villagers generally support the protection of water systems and fields; Linpan’s vacation and health and wellness functions are recognized by villagers; and regarding Linpan land use, villagers generally prefer to take the form of land market transfer and are willing to transfer arable land and homestead. This also confirms differences in the villagers’ perceptions of the conservation and utilization of Linpan in different locations due to their divergent characteristics. This study provides a reference for the villagers’ perspective on the planning and action of Linpan conservation and use, suggesting the importance of villagers’ distinguishing factors in cultural landscape revitalization.

This study provides a reference for the villagers’ perspective on the planning and action of Linpan conservation and use, suggesting the importance of villagers’ distinguishing factors in cultural landscape revitalization.","PeriodicalId":15653,"journal":{"name":"Journal of Environmental Engineering and Landscape Management","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139864351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
