摘要:

山西黄河流域是我国重要的能源与化工基地,近年来,一直面临着水土流失严重、水资源短缺等问题,研究该区域的产水服务可以为黄河流域能源化工区高质量发展提供决策参考。本文从降水变化和“三生”空间重构的视角出发,基于InVEST模型和情景模拟法,分析了2000—2020年“三生”空间变化和降水变化对流域产水服务的影响。结果表明:山西黄河流域“三生”空间整体呈现出生态>生产>生活的空间格局,生态空间面积略有减少,农业生产用地缩减明显,工矿生产、城镇生活及乡村生活用地面积增幅明显。2000年山西黄河流域的平均产水量为89.57 mm,2020年平均产水量为138.01 mm,2000—2020年产水量有所增加;通过不同情景分析表明降水变化对产水量变化的贡献率为80.4%,“三生”空间变化对产水量的贡献率为19.6%。

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%.
