丹东市宽甸县不同水土保持措施结构下综合效益评价

Comprehensive Benefit Evaluation of Different Soil and Water Conservation Measures in Kuandian County of Dandong City

以生态经济学和土壤侵蚀原理为基础,建立了基于DPSIR模型的水土保持综合评价指标体系,并在此基础上对丹东市宽甸县不同水土保持措施下的综合效益利用灰色关联投影法进行了客观评价。研究表明:宽甸县1987、2000以及2017年的水土保持综合效益投影值分别为0.112,0.185和0.246,研究期间水土保持综合效益不断提升,并以2017年达到最大;该区域水土保持措施比例结构具有较强的科学性与适用性,可为其他相似区域的水土流失治理提供一定参考。

Based on the principles of ecological economics and soil erosion, a comprehensive evaluation index system of soil and water conservation based on DPSIR model was established, and the comprehensive benefits of different soil and water conservation measures in Kuandian County of Dandong City were evaluated objectively with grey relational projection method. The results show that the projection values of the comprehensive benefits of soil and water conservation in Kuandian County in 1987, 2000 and 2017 are 0.112, 0.185 and 0.246, respectively. The comprehensive benefits of soil and water conservation have been continuously improved during the study period and reached the maximum in 2017. It will provide some references for soil erosion control.
