| 摘 要： | 根据陕西省秦岭生态功能区近十年水土流失与治理资料,选取了合理的评价指标,建立了一套较适用的水土保持治理措施评价指标体系。采用层次分析法、灰色聚类分析法和Topsis法相结合,对秦岭生态功能区水土保持治理效益进行了综合分析与评价。结果表明:秦岭生态功能区坝地面积、治理面积和水土保持林面积是评价指标体系中的主要影响因子;该地区水土保持治理效益整体呈增长趋势,各项措施已经开始发挥功效,生态效益逐步向良性发展,区域生态功能逐渐改善。该评价方法有利于秦岭生态功能区水土保持的综合管理与宏观调控,可为区域水土保持措施有效开展提供理论依据。 |

| Abstract: | Base on related data about soil and water loss and governance of region in Qinling Mountain over ten years,suitable reasonable index was selected,suitable governance index system for soil and water conversation was established.It is the application of AHP,grey clustering method and Topsis method in the comprehensive analysis and evaluation of harnessing benefit of soil and water conversation in ecological function region of Qinling Mountain.The results show that dam land area,harnessed area and soil and water conservation forest are the main affecting factors in evaluation index system.The harness benefit demonstrated the increasing trend in this region.Each measure has begun to offer the efficiency.Ecological benefit is in benign development,and the function is gradual in improvement.The application of methods is beneficial to comprehensive management and macro-control in ecological functional region in Qinling Mountain and can provide the reliable basis for effective development of soil and water conversation measures. |
| Keywords: | ecological function region in Qinling Mountain soil and water conversation benifit evaluation |
