Abstract

Abstract:

The Yellow River Basin in Shanxi Province is an important energy and chemical industry base in China. In recent years, the basis has been faced with serious soil erosion and water shortage. The study of water yield services in this region can provide decision-making reference for the high-quality development of energy and chemical industries in the Yellow River Basin. Based on the integrated valuation of ecosystem services and trade-offs and scenario simulation method, this paper analyzed the impacts of production-living-ecology spatial and precipitation changes on watershed water yield services from 2000 to 2020. The results showed the following spatial pattern regarding the “production-living-ecology space” along the Yellow River Basin in Shanxi Province: Ecology space > production space > living space. The area of ecological space slightly decreased, agricultural production land significantly decreased, and the area of land used for industrial and mining production and urban and rural living lands significantly increased. The average water yields of the Yellow River Basin in Shanxi in 2000 and 2020 were 89.57 and 138.01 mm, respectively. The water yield increased from 2000 to 2020. The contribution rate of precipitation change to the change in water yield was 80.4%, and that of “production-living-ecology” space change to water yield was 19.6%.

Key words: production-living-ecology space, water yield service, Yellow River Basin, Shanxi
