Exploring the spatiotemporal distribution and interrelationships among water-related ecosystem services (WESs) conducting ecological management zoning are crucial for regional sustainable development. Taking Xiangjiang River Basin (XJRB) as an example, this study first quantified three primary WESs, including water conservation, soil retention, purification, from 2000 to 2020. Second, variation in WESs were analyzed using global local bivariate spatial autocorrelation. Third, a rule was constructed divide watershed into eight secondary zones.

The Yellow River Basin (YRB) plays a very important role in China’s economic and social development ecological security, so studying the spatiotemporal variation characteristics of net primary productivity (NPP) its influencing factors is great significance for protecting stable environment. This article takes YRB as research area, based on Moderate Resolution Imaging Spectroradiometer (MODIS) data, climate terrain land gravity recovery experiment (GRACE) data. evolution vegetation NPP from 2000 to 2022 were explored using methods such trend analysis, correlation geographic detectors, with meteorological factors, total water storage (TWS) evaluated. results indicate that showed an increasing (4.989 gC·m−2·a−1) 2022, most significant changes occurring middle reaches YRB. coefficient indicates temperature accumulated have positive impact change NPP, while TWS has negative impact. In study affecting YRB, influential are soil type (0.48), precipitation (0.46), (0.32). strong between about 39%, contribution rate 0.12, which factor cannot be ignored

Ecosystem services (ES) such as carbon storage (CS), soil conservation (SC), habitat quality (HQ), and water yield (WY) play a crucial role in maintaining ecological balance supporting sustainable regional development. With increasing environmental changes, understanding the spatiotemporal dynamics of these their driving factors has become essential science. This study focuses on Nanchang metropolitan area, quantifying CS, SC, HQ, WY from 2000 to 2020. It explores impacts major factors, including climate, topography, social aspects, spatial heterogeneity ES. The results reveal that between 2020, CS HQ decreased by 0.1385×108 tons/ha 0.0507, respectively, while SC increased 2.4754×10 9 1.6668×10 10 m 3 , respectively. Notable exists correlation changes distribution ESs is higher mountainous regions compared central plains. Among human population (POP) gross domestic product (GDP) predominantly influenced whereas climate POP drove SC. Changes were primarily affected topography. These findings suggest need focus key formulate targeted land policies aimed at enhancing ES value area.

In order to explore the impact of water resources development and utilization on ecological environment Taohe River Basin coordinate relationship between energy protection, this paper analyzes by using data runoff, sediment, land use types remote sensing index for many years. The results show that: 1) After construction hydropower station, proportion runoff in flood season is relatively reduced, while non-flood increased; quantity decreased summer autumn increased winter. 2) silt mainly comes from period, sediment transport largest, up 82.26% annual transport; showed a decreasing trend 1991 2021. 3) During 40 years 1980 2020, transfer area grassland, forest cultivated has been changed some extent, but small difference transferred out, resulting overall change study during period was not large. 4) RSEI 1990 2020 at medium level, an upward trend; spatial distribution shows pattern "upstream better than downstream", areas with poor environmental quality are concentrated downstream areas.

Enhancing the supply efficiency of ecosystem services plays a central role in improving both natural ecosystems and human well-being. Taking Loess Plateau Northern Shaanxi as an example, this study utilizes InVEST to assess water yield habitat quality. The optimal solutions for combination these two are calculated on basis Pareto principle. production possibility frontier curves fitted, services’ is measured. Furthermore, employs ordinary least squares geographically weighted regression analyze dominant factors affecting efficiency. results comprise following findings: (1) There eighteen representing combinations between services. (2) increases from northwest southeast spatial distribution. (3) vary among different zones Population, hydrology, gross domestic product (GDP) general-efficiency, sub-low-efficiency, low-efficiency zones, respectively. Hydrology, NDVI, GDP sub-high-efficiency zone, while GDP, terrain, population high-efficiency zone. In conclusion, paper proposes recommendations reducing trade-offs enhancing These include dynamic supervising moderate greening stabilizing general-efficiency development intensity low- sub-low-efficiency zones. reveals potential approaches offers guidance formulating ecological protection plans.
