ClearEvaluation of the Spatiotemporal Change of Ecological Quality under the Context of Urban Expansion—A Case Study of Typical Urban Agglomerations in China
Researchers tracked changes in ecological quality across three major urban areas in China over two decades of rapid urbanization. They found that urban expansion significantly reduced ecological quality in surrounding areas, with the most severe impacts occurring in newly developed zones. The study provides a framework for monitoring how urbanization affects local ecosystems using remote sensing data.

Urbanisation and specifically impervious cover alter riparian plant communities in a rapidly urbanising landscape in the Himalayas
Researchers studied how urbanization and impervious surfaces like roads and buildings affect riparian plant communities along rivers in the Himalayas. The study found that expanding impervious cover along riverbanks significantly alters species diversity and composition, threatening these important transitional ecosystems in a rapidly developing region.
Effects of Urbanization on Landscape Patterns in the Middle Reaches of the Yangtze River Region
This remote sensing study analyzed how urbanization changed land use and landscape patterns in the middle Yangtze River region of China over several decades. Rapid urbanization replaced natural vegetation with impervious surfaces, reducing ecosystem services like water filtration. Urban expansion is closely linked to increases in plastic consumption and microplastic pollution in adjacent water bodies.
Spatiotemporal Variations of Human Pressure on Key Biodiversity Areas in the Qinghai–Tibet Plateau: A Comparative Analysis
Researchers analyzed spatiotemporal changes in human pressure on key biodiversity areas across the Qinghai-Tibet Plateau from 1990 to 2017, finding that conservation policies enacted after 2010 helped slow but not fully reverse increasing anthropogenic pressures on these ecologically sensitive zones.
Quantitative Contributions of Climate and Human Activities to Streamflow and Sediment Load in the Xiliugou Basin of China
Researchers analyzed 30 years of data from the Xiliugou Basin in China to quantify how climate change and human activities have affected streamflow and sediment transport. The study found that human activities, particularly land-use changes, were the dominant factor driving decreases in both streamflow and sediment load, with an abrupt shift occurring around 1997.
Assessing land-use impacts on a 5th-order tropical river using multiple environmental indicators
Researchers combined multiple environmental indicators to assess the health of a tropical river system in Brazil affected by land-use change from agriculture and urbanization. Rivers in degraded landscapes also carry higher microplastic loads, and multi-indicator approaches provide a more complete picture of ecosystem health.
Analysis of Land Use Evolution of Suzhou Wetlands Based on RS and GIS
Researchers used satellite remote sensing and GIS to track changes in land use and wetland coverage in Suzhou, China over time. Understanding how wetland ecosystems change is important for assessing their capacity to filter pollutants, including microplastics carried by stormwater and runoff.
Biomonitoring for Watershed Protection from a Multiscale Land-Use Perspective
This review of freshwater biomonitoring studies examined how different land use types affect aquatic organisms across temporal and spatial scales, finding that land use intensity strongly influences bioindicator responses and recommending that biomonitoring programs consider multiple scales and eDNA approaches.
Analysis of hydrochemical characteristics and genesis of water-deficient rivers in China: a case study of the Ciyao River Basin in Shanxi Province
This study analyzed the chemical characteristics and origins of water in the Ciyao River Basin, a water-scarce region in China's Shanxi Province. Researchers collected water samples across wet, normal, and dry seasons and found that the water chemistry was influenced by both natural rock weathering and human activities. The findings provide baseline data for managing water quality in regions where water scarcity makes understanding pollution sources especially critical.
Effects of land use on the distribution of soil microplastics in the Lihe River watershed, China
Researchers surveyed microplastic contamination across five different land use types in a Chinese river watershed. They found that urban soils had the highest microplastic levels, followed by agricultural areas, with woodland having the lowest, and that population density strongly correlated with microplastic diversity. The study suggests that human activity intensity and plastic waste disposal are the main drivers of soil microplastic pollution at the watershed scale.
Impacts of land use/land cover on water quality: a contemporary review for researchers and policymakers
This review examines how different land uses, from farming to urban development, affect water quality through diffuse pollution. Natural vegetation acts as a protective buffer against contamination, but more research is needed to determine how much vegetation is required to effectively filter pollutants. The findings are relevant to microplastic pollution because urban runoff and agricultural land use are major pathways by which microplastics enter drinking water sources.
Water Quality Analysis and Its Impact on Biodiversity in Freshwater Ecosystems
Researchers measured physicochemical water quality parameters and biological communities at five freshwater sites with varying degrees of anthropogenic disturbance, using correlation analysis, PCA, and cluster analysis to link water quality to aquatic biodiversity. They found strong positive correlations between dissolved oxygen and species richness, and significant negative associations between BOD, nitrate, heavy metals, and biodiversity, concluding that degraded water quality directly compromises freshwater ecosystem function.
Ecological Zoning Based on Value–Risk in the Wuling Mountains Area of Hunan Province
Researchers assessed ecological zoning in China's Wuling Mountains region based on ecosystem service value and ecological risk from 2000 to 2020. They found that both overall ecosystem value and ecological risk increased over the study period, with forests providing over 77% of the total ecosystem service value. The study provides a framework for ecological planning that accounts for environmental risks, including those from pollution and land use changes.
Watershed Ecohydrological Processes in a Changing Environment: Opportunities and Challenges
This review examines watershed ecohydrological processes under changing environmental conditions, including the impacts of climate change and human activities on water quantity and quality. Researchers propose a new integrated framework for watershed management that incorporates socioeconomic activities alongside ecological and hydrological monitoring. The study identifies emerging environmental concerns, including microplastic pollution, as factors that need to be incorporated into modern watershed management strategies.
Vegetación riparia y la calidad del recurso hídrico en la zona centro del litoral Ecuatoriano
Researchers evaluated riparian vegetation quality and its relationship to water resource quality in the central coastal zone of Ecuador, finding that despite abundant water availability, rural areas lack access to quality water and that agricultural expansion is reducing protective riparian vegetation.
Relationships between microplastic pollution and land use in the Chongqing section of the Yangtze River
Researchers analyzed the relationship between land use patterns and microplastic pollution across 26 monitoring sites in the Yangtze River's Chongqing section. They found that microplastic concentrations were highest in urban areas and declined downstream, and that pollution levels dropped approximately 7.5-fold between 2016 and 2020, likely due to improved waste management. The study suggests that the amount of surrounding urban and garden land strongly predicts river microplastic levels, highlighting the connection between city planning and water quality.
