The water-level of Three Gorges Reservoir first reached a normal storage level 175 m in October 2010, resulting large-area water-fluctuating zone with an elevation difference 30 (145–175 m). We used the Geographic Information System (GIS) technology, field quadrat survey, species importance value calculation, and literature data to assess natural environment situation, vegetation regeneration status, ecological benefits dominant plant terms mitigating agricultural non-point source pollution...
Agricultural non-point source pollution (AGNPS) risk prevention and control is more conducive to reducing costs than post-treatment. Therefore, how effectively identify risks a key problem be solved. The study area located in the NANTUO small watershed of Three Gorges Reservoir Area China, on side Yangtze River, where agriculture developed with many kinds plantings. There water level fluctuation zone (WLFZ) seasonal elevation difference up 30 m due regulation reservoir, which hot AGNPS...
Human health is adversely affected by potentially toxic elements (PTEs) in the topsoil, entering bodies via inhalation, ingestion, and dermal contact. To visualize human risks, we investigated five PTEs (Cd, As, Pb, Hg, Cr) 72 farmland topsoil samples from a town Chongqing City, southwest China. Based on risk assessment model, sequential indicator simulation (SIS) positive matrix factorization model (PMF) were used to construct spatial risks analyze sources of PTEs; finally, combined with...
The Fuling District is located in central Chongqing, China, and characterized by a high ecological status, risk, agricultural proportion economy, non-point source pollution (AGNPS) represents the security barrier of Yangtze River Three Gorges Reservoir area. To analyze output risk response AGNPS under different land use scenarios future, we combined advantages various models techniques such as CLUE-S model, Markov SWAT GIS technology selected 12 driving factors for changes well one limiting...
The relationship between land use changes and regional carbon storage is closely linked. Identifying evolving trends concerning influencing factors on under future scenarios key in order to achieve the “dual carbon” goals. Using Chongqing as a case study, this study integrated advantages of PLUS model, InVEST geographic detector model. It conducted simulations type data natural development (ND) ecological protection (EP), identified regarding storage. results were follows: (1) model...
Carbon sink service (CSS) is crucial in addressing global warming and provides theoretical support for research on human‒system coupling. CSS generation, flow, utilization the composite ecosystem of mountains, rivers, forests, farmlands, lakes, grasslands (CEMRFFLG) sustainable development. Quantifying coupled supply‒flow‒demand processes mechanisms CEMRFFLG remains a pressing issue study carbon flows (CSSFs). First, quantify supply demand situation Chongqing. Second, coupling process CSSF...
The management of regional eco-environmental risks is the key to promoting economic sustainability from macro level, and accurate evaluation evolutionary trends ecological risk in future high importance. In order clearly identify possible impact development scenario selection for Chengdu-Chongqing Economic Zone (C-C E Zone) on evolution landscape (LER), we introduced Patch-generating Land Use Simulation (PLUS) model simulate land use data C-C 2030 2050 two scenarios: natural (ND) protection...
Abstract To determine the risk state distribution, level, and evolution situation of agricultural non-point source pollution (AGNPS), we built an ‘Input-Translate-Output’ three-dimensional evaluation (ITO3dE) model that involved 12 factors under support GIS analyzed spatiotemporal characteristics AGNPS risks from 2005 to 2015 in Chongqing by using space matrix, kernel density analysis, Getis-Ord Gi* analysis. Land use changes during 10 years had a certain influence on risk. The values 2005,...
Rural green development is a concrete practice of rural revitalization. Currently, research on quantitative evaluation methods for levels are not well developed. In this study, an model the level in Chongqing City, China was developed based parameters ecology, living, and production. An entropy weight method, Theil index, optimal scale regression model, GIS were used to analyze spatio-temporal characteristics, trends, influencing factors from 2018 2020 City. The results showed that: (1)...
Analysis of the relationship between future land use change and agricultural non-point source pollution (ANPSP) evolution is vital to promoting sustainable regional development. By simulating types, we can identify analyze trend ANPSP. This study takes Chongqing as a case establish an integrated solution based on PLUS model, output coefficient GIS technology. The simulate data, trends, key control areas under development scenarios. results show that model types at provincial scale with high...
Urban rivers represent a unique ecosystem in which pollution occurs regularly, altering the biogeochemical characteristics of waterbodies and sediments. However, little is presently known about spatiotemporal patterns planktonic sediment bacterial community diversities compositions urban rivers. Herein, Illumina MiSeq high-throughput sequencing was performed to reveal dynamics populations Liangtan River, heavily polluted river Chongqing City (China). The results showed richness diversity...
According to China’s second national survey of pollution sources, the contribution agricultural non-point sources (ANS) water is still high. Risk prevention and control are main means costs improve efficiency ANS, but most studies directly take load as risk standard, leading a considerable misjudgment actual risk. To objectively reflect source (ANSP) in Chongqing, China, we investigated influences initial input, intermediate transformation, terminal absorption pollutants via literature...
Explore the application of Delphi method and analytic hierarchy process to explore construction scientific, objective comprehensive evaluation index system for healthy enterprise promote enterprises.
The exploration of ecological security patterns (ESPs) can help people find those areas that are in urgent need restoration, which is an effective way to realize protection. It utmost significance for promoting regional sustainable development construct ESP and put forward sub-regional optimization suggestions based on the supply demand ratio ecosystem services (ESs). In this paper, we assessed level five ESs multi-source data 2020 with InVEST, ArcGIS, IUEMS. Based results demand, calculated...
This study comprehensively examined the accumulation of cadmium (Cd) in soybeans grown low- and high-Cd soils around high geological background areas Guizhou province. The aim was to analyze relationship between soybean Cd soil pH Cd, alongside assessing potential carcinogenic non-carcinogenic risks associated with soybeans. content cultivated area (0.430 mg/kg) significantly higher than that low-Cd (0.156 (P < 0.05). Biological concentration factors (BCFs) for were 0.282 0.314,...
Green development is key to promoting regional sustainable development. We construct an evaluation index system for green levels based on the “sansheng” dimensions—production, living, and ecology. rely (production, ecology) dimensions, combined with analytic hierarchy process (AHP) entropy weight method analyze indicator weights, levels. This enables identification of evolution patterns analysis driving factors in Chengdu-Chongqing economic zone from perspective. The results indicate that:...
Due to the insufficient research on spatial relationship and driving mechanism of ecosystem services ecological risks current background rising dysfunctional in local areas, analyzing is an urgent task order safeguard regional security improve at present. Taking Chongqing as example, study scientifically identifies between their factors district county scales based constructed Ecosystem Service—Driver–Pressures–Status–Impacts–Responses (ES-DPSIR) model.
