| 摘要: |
| 【目的】 评价陕北黄土高原县域水土保持治理的适宜性。【方法】 选取陕北延安地区的安塞、子长、延川3县和榆林地区的米脂、绥德、神木3县共6县的多年观测资料，建立了黄土高原县城水土保持治理适宜性评价指标体系，应用层次分析法对各县域水土保持治理适宜性进行了分析评价。【结果】 在陕北黄土高原水土保持治理过程中，坝地面积、治理度和单位面积投资是该地区水土保持评价体系的主要影响因子，在实际运用中要给予一定关注；所选6个县的水土保持治理适宜性综合评价分值表明，各县域的水土保持治理与当地社会经济的适宜性逐渐向良性发展，且评价结果与实际情况相符合。【结论】 建立的县域水土保持治理适宜性评价指标体系较好地反映了当地的实际情况，是科学、可行的。 |

| Abstract: |
| 【Objective】 The study evaluated the suitability of soil and water conservation of counties in Loess Plateau.【Method】 Years’observation data of Ansai, Zichang, Yanchuan, Mizhi, Suide, and Shenmu county in northern Shaanxi were selected,a comprehensive governance index system for soil and water conservation was established,and AHP was applied in the analysis and evaluation of suitability of soil and water conservation in Loess Plateau.【Result】 The results show that dam land area governance degree and unit area investment are main affecting factors in soil and water conservation evaluation system in these areas,and more concern shonld be given to these factors in practical application;the comprehensive evaluation scores of the 6 counties indicate that the situation of soil and water conservation can develop sustainably,and the evaluation results are in accordance with actual situation.【Conclusion】 The suitability of evaluation system of soil and water conservation reflects the actual situation,and the application of the evaluation system can provide reliable basis for scientific evaluation of water conservation measures. |
