生产建设项目水土保持综合评价

生产建设项目水土保持综合评价是不同项目分类治理的依据。采用层次分析法,以生产建设项目水土保持最主要的水土流失状况、水土保持防治效果、水土流失危害3个方面为基础,构建了水土保持评价模型,并对不同类型生产建设项目水土保持效益进行了分析。结果表明,点状生产建设项目水土保持效益要大于线状项目,点状项目水土保持效益波动性比线状项目要小;点状生产建设项目中房地产类项目水土保持效益最大,其次为电厂项目,最后为矿场项目,水土保持效益波动性从大到小顺序依次为电厂项目、矿场项目、房地产项目。

Comprehensive Evaluation of Soil and Water Conservation in Development and Construction Projects

Comprehensive evaluation of soil and water conservation in a development and construction project is the base of category management. Analytic hierarchy process is used to construct an evaluation model of soil and water conservation based on the status of soil erosion, effects of soil and water conservation and soil erosion harms. Moreover, different types of development projects are analyzed. Results showed that soil and water conservation benefits for point projects are better than linear projects, but the fluctuation of soil and water conservation benefits is smaller than linear projects. Soil and water conservation benefits for real estate project are the biggest; power plant project, the second; and mine project, the worst. The fluctuation of soil and water conservation benefits, from largest to smallest, is in the order of power plant project, mine project and real estate project.
