Abstract
Assessing the water yield function of a river basin is crucial for hydrological ecosystem protection. This research took the Nansihu River Basin as a case and evaluated its water yield from 2000 to 2022. The results showed that: (1) Water yield decreased 33.51% over the 20 years, from 369.91 mm to 220.06 mm, with the peak occurring in 2005. Both precipitation and evapotranspiration were positively correlated with water yield and exhibited similar trends and spatial distributions. (2) Water yield declined from the eastern mountainous areas to the western plains, with significant reductions ranging from − 200 to -100 mm in the western plains, while the central area remained stable. (3) Climatic factors significantly impacted water yield, and LULC determined its distribution. Non-natural areas produce three times the water yield of natural areas. These results are instrumental in guiding water resource management strategies within the basin.
期刊介绍：
Environmental Earth Sciences is an international multidisciplinary journal concerned with all aspects of interaction between humans, natural resources, ecosystems, special climates or unique geographic zones, and the earth:
Water and soil contamination caused by waste management and disposal practices
Environmental problems associated with transportation by land, air, or water
Geological processes that may impact biosystems or humans
Man-made or naturally occurring geological or hydrological hazards
Environmental problems associated with the recovery of materials from the earth
Environmental problems caused by extraction of minerals, coal, and ores, as well as oil and gas, water and alternative energy sources
Environmental impacts of exploration and recultivation – Environmental impacts of hazardous materials
Management of environmental data and information in data banks and information systems
Dissemination of knowledge on techniques, methods, approaches and experiences to improve and remediate the environment
In pursuit of these topics, the geoscientific disciplines are invited to contribute their knowledge and experience. Major disciplines include: hydrogeology, hydrochemistry, geochemistry, geophysics, engineering geology, remediation science, natural resources management, environmental climatology and biota, environmental geography, soil science and geomicrobiology.
