摘　　要：在水土保持目标责任考核中,存在不同地域水土流失危害差异性、防治任务多样性及发展不平衡性等问题,因此,建立科学合理的考核指标体系是客观公正评价各级政府水土保持工作完成情况的前提。运用层次分析法结合熵值法修正指标评价权重,构建甘肃省考核指标体系及评价模型。该模型除责任追究负面影响指标(2个)外由3个一级指标、9个二级指标和17个三级指标组成。一级指标含水土流失预防保护、综合治理、综合监管3个任务指标(其综合指标评价权重分别为0. 400 0、0. 200 0和0. 400 0)。水土流失预防保护指标中方案编报率最大(0. 198 7),综合治理指标中新增治理面积最大(0. 120 0),综合监管指标中监督执法最大(0. 148 6),重点体现了政府水土流失防治责任的重要指标和直接指标。该评价模型中> 10%的指标有:生产建设项目水土保持方案编报率(C3)、水土流失重点预防区受保护面积(C1)、生产建设项目监督执法(D9)、新增水土流失治理面积(C4) 4项指标,占总权重的61. 80%。考核指标体系及评价模型充分体现了预防为主、保护优先、突出重点、科学管理的要求,也可为甘肃省及同类地区水土保持目标责任考核工作提供参考,可为全国水土保持规划实施考核提供基础数据。[Background] Currently,there are differences in the types,intensities and hazards of soil erosion,the diversities and complexities of prevention and control tasks of soil erosion,and the imbalance of social and economic development in different administrative regions. It is difficult to measure the implementation of soil and water conservation work of local governments with a single soil and water conservation target responsibility indicator. Gansu province is one of the provinces with the most serious soil erosion. Therefore,establishing a soil and water conservation target responsibility assessment index system and assessment model composed of certain hierarchical indicators would help to accurately evaluate the level,science and integrity of soil and water conservation in Gansu province in terms of ecological environment construction. [Methods] The analytic hierarchy process( AHP) was used to construct the judgment matrix,calculate the index evaluation weight( W),and the test index rationality( indicator consistency ratio CR< 0. 1). After the index test was passed,the entropy method was used to modify the weight of the index evaluation obtained by the AHP,and determine the revised comprehensive evaluation weight( P),as well as to establish the assessment index system and evaluation model of Gansu province.[Results]Gansu province’s soil and water conservation target responsibility assessment index system is constructed from the aspects of prevention and protection of soil erosion,comprehensive management,comprehensive supervision and accountability,the hierarchical structure consists of a target level( A),a criterion level( Bi),an operation level( Cj),and a sub-operation level( Dk). When establishing a water and soil conservation target responsibility assessment index evaluation model,the responsibility investigation is a negative impact indicator( 2),and it is no need to give weights. The first-level indices are composed of three task indices,which are prevention and protection,comprehensive management and c
