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.
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.
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.
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.
Assessment of Uncertainties in Ecological Risk Based on the Prediction of Land Use Change and Ecosystem Service Evolution
Using the PLUS land use change model, researchers simulated future land use scenarios in southern China and evaluated how projected changes would alter ecosystem services and associated ecological risk under uncertainty.
Spatiotemporal Dynamics of Land Use Changesand Their Impacts on Ecosystem ServiceValue in the Qinghai Lake Basin, 2003-2023
Researchers examined spatiotemporal land use changes and their effects on ecosystem service value in the Qinghai Lake Basin of the Qinghai-Tibet Plateau over a 20-year period from 2003 to 2023. The study found that land use alterations significantly disrupted biodiversity, soil retention, water conservation, and overall ecosystem service value in this important inland saltwater lake 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.
[Occurrence Characteristics and Ecological Risk Assessment of Microplastic Pollution in the Yellow River Basin].
Researchers examined the spatial distribution, composition characteristics, and ecological risks of microplastic pollution across the Yellow River Basin in China, assessing contamination levels in the nation's historically significant waterway system.
Integrated Ecological Risk Assessment of the Agricultural Area under a High Anthropopressure Based on Chemical, Ecotoxicological and Ecological Indicators
Researchers conducted an integrated ecological risk assessment of agricultural land using chemical, ecotoxicological, and ecological indicators, finding that while chemical analysis overestimated risk, the combined approach revealed most of the area had acceptable risk levels despite over a century of anthropogenic pressure.
Distribution pattern and ecological risk assessment of heavy metals in Henan section of the Yellow River
Researchers assessed heavy metal pollution in sediments of the Henan section of the Yellow River, finding elevated concentrations of several metals including cadmium and lead, with ecological risk assessments indicating moderate to high risk in certain areas driven by both natural and anthropogenic inputs.
Yellow River Basin Management under Pressure: Present State, Restoration and Protection II: Lessons from a Special Issue
This review assessed the current state of the Yellow River Basin's water environment, covering sediment dynamics, pollution loads, and restoration challenges, along with management interventions aimed at improving ecological conditions. The authors document improvements from recent restoration policies but identify persistent pressures from agriculture, industry, and climate change threatening the basin's long-term water security.
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.
Assessing wetlands ecological risk through an adaptive cycle framework
Not relevant to microplastics — this paper develops an ecological risk assessment framework for wetlands based on adaptive cycle theory, applied to Kunshan, China, focusing on climate change and human impacts rather than plastic contamination.
Non–Negligible Ecological Risks of Urban Wetlands Caused by Cd and Hg on the Qinghai–Tibet Plateau, China
Researchers assessed heavy metal contamination in the Huangshui National Wetland Park on the Qinghai-Tibet Plateau, finding that cadmium and mercury pose non-negligible ecological risks across the urban wetland's three zones.
Distribution of microplastics in Lanzhou section of the Yellow River: Characteristics, ecological risk assessment, and factors analysis
Researchers surveyed microplastic contamination in surface water and sediments along the Lanzhou section of China's Yellow River. They found that most particles were small fibrous fragments of PET and polypropylene, with higher abundances during the dry season, and that human activity and weather patterns influenced microplastic distribution. Ecological risk assessments indicated the overall pollution level in this stretch of the river was relatively low.
Evaluation of plateau wetland ecological security and its influencing factors in multi-climatic zones: A case study of Yunnan Province
Not a microplastics paper — this study assesses the ecological security of plateau wetlands across Yunnan Province, China using a pressure-state-response model based on remote sensing data, identifying climate and human activity as key threats to these fragile ecosystems.
The Changes in Dominant Driving Factors in the Evolution Process of Wetland in the Yellow River Delta during 2015–2022
This paper is not about microplastics; it uses satellite time-series imagery to analyze changes in wetland area and type in the Yellow River Delta between 2015 and 2022.
Microplastic pollution characteristics and ecological risk assessment in the Wuding River Basin, China
Researchers surveyed microplastic pollution in the Wuding River, a tributary of China's Yellow River, collecting samples from 19 sites across water and sediment. They found that microplastic abundance varied significantly across locations, with fibers being the dominant shape, and identified population density and land use as key factors influencing contamination levels. The ecological risk assessment indicated that certain areas of the basin face moderate to high risk from microplastic pollution.
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.
