【摘要】：以陕西水源区为对象,运用因子分析法和专家咨询法从基础效益、生态效益、经济效益和社会效益4个方面构建了水土保持效益评价体系,并基于改进的层次分析法确定各指标权重,运用模糊综合评价法衡量了水土保持项目效果。结果表明:总体来看,水土保持项目改善了陕西水源区整体质量,但在不同效益之间存在差异。基础效益方面表现最优,治理度、土地利用率、道路硬化率等有大幅提升;生态和经济效益方面表现次之,森林覆盖率、环境质量提高率和资金产投比等提升不够明显;经济和社会效益还有很大发展空间,项目对受教育程度、农产品商品率等拉动不足。该研究为南水北调工程水土保持项目的进一步实施提供了科学依据。
[Abstract]:In this paper, the evaluation system of soil and water conservation benefit is established by using factor analysis method and expert consultation method in the water source area of Shaanxi Province from four aspects: basic benefit, ecological benefit, economic benefit and social benefit. Based on the improved Analytic hierarchy process (AHP), the weight of each index is determined, and the effect of soil and water conservation project is evaluated by fuzzy comprehensive evaluation method. The results show that the overall quality of water and soil conservation project has been improved in Shaanxi province. But there are differences between different benefits. The performance of basic benefit is the best, the degree of governance, the rate of land utilization, the rate of road hardening, etc., the ecological and economic benefits are the second, the forest coverage, The improvement rate of environmental quality and the ratio of capital, production and investment are not obvious enough; there is still much room for development in the economic and social benefits. The research provides scientific basis for the further implementation of soil and water conservation project of South-to-North Water transfer Project.
