摘　　要：以秃尾河流域为例,从地下水与表生生态环境关系的野外调查入手,以地下水为主线,在深入分析流域表生生态环境问题的驱动力的基础上,建立了流域表生生态环境递阶层次评价指标体系,并对流域表生生态环境现状进行了评价。评价结果表明,流域生态环境现状总体较好,其中盖沙丘陵区和沙漠区是流域水资源与生态环境保护的重点。According to the results of field investigation on the relationship between groundwater and supergene ecoenvironment in Tuwei river watershed, the influencing factors of supervene eco-environment problems were analyzed. An assessment index system of supervene eco-environment was established, and the present state of supergene ecoenvironment was assessed as well. The results show that the environment is good as a whole, but the hilly area covered with sand and the desert area are key areas in the protection of water resources and eco-environment in the watershed.
