ClearQuantitative 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.
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.
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.
Response of Matching Degree between Precipitation and Maize Water Requirement to Climate Change in China
This study examined how climate change is altering the matching between precipitation timing and maize water requirements across China's monsoon region. Changes in intra-annual precipitation distribution and extreme weather frequency were found to affect crop water availability, with significant implications for food security.
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.
Response Time of Vegetation to Drought in Weihe River Basin, China
This is a hydrology study analyzing how vegetation in China's Weihe River Basin responds to drought using satellite vegetation indices; it is not a microplastics research paper.
Eco-Asset Variations and Their Driving Factors in the Qinghai–Tibet Plateau, China, under the Context of Global Change
This paper is not relevant to microplastics research — it analyzes ecological asset changes and their environmental drivers on the Qinghai-Tibet Plateau using remote sensing data.
Research on Vegetation Ecological Security in Arid Region Mountain Front River Valleys Based on Ecological Water Consumption and Water Demand
Researchers quantified ecological water consumption and water demand for valley vegetation in an arid mountain-front region over 30 years, using the results to simulate groundwater levels and assess ecological security thresholds. They found total annual water demand of approximately 4.82 x 10^8 m3 concentrated in June-August, with groundwater levels declining at roughly twice the rate in areas farther from rivers, threatening vegetation ecological 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.
Quantifying desertification in the Qinghai Lake Basin
This paper is not about microplastics. It studied desertification patterns in the Qinghai Lake Basin on the Tibetan Plateau using satellite vegetation and albedo data over 20 years. The study found that desertification has reversed in recent decades but remains concentrated along the northwestern basin boundaries. It has no connection to microplastic pollution or human health.
Spatiotemporal Analysis of the Impacts of Climate Change on UAE Mangroves
Researchers analyzed spatiotemporal changes in UAE mangrove ecosystems using remote sensing, finding that climate variables such as land surface temperature and salinity significantly influenced mangrove growth and distribution patterns over time.
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.
Evaluation 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.
The concept, approach, and future research of hydrological connectivity and its assessment at multiscales
Researchers reviewed the concept of hydrological connectivity — the water-mediated transfer of matter and energy across landscapes — examining how dam construction, land management, and climate factors alter it, and identifying numerical modeling and connectivity indices as the most useful tools for its assessment across spatial scales.
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.
