摘 要：
依据土壤侵蚀原理和生态经济学原理等理论,基于DPSIR模型,构建了适合区域水土保持综合效益评价的指标体系,运用灰色关联投影法,对定西市安定区不同水土保持措施结构下的综合效益进行了科学系统的评价。评价结果表明:1993年、2000年和2010年水土保持综合效益投影值分别为0.116 1,0.190 3,0.218 4。水土保持综合效益值在2010年达到最大,其相对应的措施结构为该地区水土保持综合治理较优的措施比例结构。

摘 要：
In this article,we established a suitable soil and water conservation benefit evaluation index system according to soil erosion principle,sustainable development theory,ecological economic theory,and DPSIR model.With gray relation projection method,the overall efficiency of Anding District of Dingxi City under different conservation measures of the structure was evaluated reasonably.The results showed that numerical projected values of benefit soil and water conservation in 1993,2000and 2010were 0.116 1,0.190 3and0.218 4,respectively.Soil and water conservation comprehensive benefits reach the maximum value in 2010.So,the structure of the corresponding measures should be optimum for the comprehensive management of soil and water conservation measure structure.
