- Abstract:
- Taking the water source area in Shaanxi Province as the site and applying factor analysis method and expert consultation method, we built an evaluation system for water and soil conservation in four aspects: basic benefits, ecological benefits, economic benefits, and social benefits. In addition, the index weight is determined on the basis of improved analytical hierarchy process, and the outcome of water and soil conservation project is measured by vague comprehensive evaluation method. Results show that the soil and water conservation project has improved the overall quality of the water source area in Shaanxi Province. But there are differences between benefits. Basic benefits show optimal performance with a dramatical increase in governing force, land utilization rate, road-hardening rate and so on. Ecological and economic benefits come in second due to obvious insufficient increase in forest coverage rate, environmental quality improvement rate, and capital ratio. There is still large development potential for social benefits. The project doesn’t show enough boosting effect on educational degree and marketable agricultural products. The study can provide scientific basis for further implementation of soil and water conservation project in South-to-North Water Diversion Project.
