ClearEffects 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.
Urbanization and the Emerging Water Crisis: Identifying Water Scarcity and Environmental Risk with Multiple Applications in Urban Agglomerations in Western China
Researchers developed a comprehensive index system to evaluate water scarcity and environmental risk across three major urban regions in Western China. They found that rapid urbanization has significantly worsened water resource shortages and ecological vulnerability in these areas. The study provides a framework for understanding how urban growth intensifies water stress and suggests approaches for sustainable water resource management.
Landscape Ecological Risk Assessment Based on Land Use Change in the Yellow River Basin of Shaanxi, China

Impact of watershed habitat quality based on land use: a case study of taking Ciyao River Basin
Land use change analysis in the Ciyao River Basin from 1985 to 2020 showed that habitat quality declined in areas with increased agricultural and urban expansion, highlighting land use as a key driver of watershed ecological health. The findings support land use planning as a tool for biodiversity and water resource protection.
Spatiotemporal changes in land use and residential satisfaction in the Huai River-Gaoyou Lake Rim area
Researchers used two decades of satellite data to track land use changes and ecological risks in China's Jiangsu Province, focusing on shifts between agricultural, urban, and wetland areas. Land use changes alter how plastic waste and microplastics are transported and deposited in freshwater ecosystems.
Rural Ecological Problems in China from 2013 to 2022: A Review of Research Hotspots, Geographical Distribution, and Countermeasures
This review analyzed a decade of research on rural ecological problems in China from 2013 to 2022, identifying key hotspots including soil contamination, water pollution, and biodiversity loss driven by rapid urbanization and industrial development, and summarizing proposed countermeasures.
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.
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.
Dynamic Changes of Local Climate Zones in the Guangdong–Hong Kong–Macao Greater Bay Area and Their Spatio-Temporal Impacts on the Surface Urban Heat Island Effect between 2005 and 2015
Researchers mapped changes in local climate zones in China's Greater Bay Area between 2005 and 2015 and quantified how urban land cover shifts drove increases in surface urban heat island intensity, finding that compact urban development produced the greatest warming contributions.
Conditions of Mainland China’s Island Ecosystems and Associated Influencing Factors: Integrated Assessment of 42 Typical Island Ecosystems
Researchers assessed the ecological condition of 42 representative islands along China's coast using a framework integrating environmental quality, biological structure, and landscape patterns, finding that island ecosystem health varied significantly by size, location, and human land use intensity.
A Comprehensive Method for Water Environment Assessment considering Trends of Water Quality
Researchers developed a comprehensive water quality assessment method that accounts for both current pollution levels and trends over time, applying it to rivers feeding a major Chinese reservoir. Water quality assessment frameworks are increasingly being adapted to include microplastic contamination as a standard monitoring parameter.
Exploring the spatiotemporal effects of urban scale and urban vitality on S&D balance in the Yangtze River Delta, China from 2015 to 2025
Researchers analyzed how city growth and economic activity affect the balance between what ecosystems provide (like clean water and clean air) and what people demand in China's Yangtze River Delta, finding that larger urban areas strain this balance while targeted development strategies can help certain regions maintain healthier ecosystems.
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.
Long-term human expansion and the environmental impacts on the coastal zone of China
This study analyzed long-term expansion of reclamation, aquaculture ponds, and urban land cover in the Circum-Bohai Coastal Zone of China from satellite data using Google Earth Engine. Human coastal expansion accelerated significantly over the study period and was associated with declining ecosystem services including carbon storage, water purification, and biodiversity habitat.
Ecological Waves at Tourist Attractions on the Qinghai-Tibet Plateau Promote Greenness of Surrounding Vegetation
