- 摘要:
- 水土保持综合效益评价指标众多，不同地区由于自然、社会和经济条件相差很大，评价指标的选取也不同。在对川东丘陵地区进行实地调查、走访、查阅当地资料、专家咨询的基础上确定了包括目标层、准则层和指标层的三级评价指标体系，包括20个评价指标，这些指标以量化为主，基本能够反映区域水土保持综合效益。在对不同效益评价方法进行分析的基础上，提出了利用层次分析法进行水土保持综合效益评价的方法，对丁家河小流域治理后水土保持综合效益进行了评价，结果表明，治理后小流域水土保持综合效益得分值为0.091 6，各准则层效益表现为社会效益 > 调水保土效益 > 生态效益 > 经济效益，评价结果与当地实际相符合，表明本研究所建立的评价指标体系合理，评价方法可行，可应用于川东丘陵区水土保持综合效益评价，为川东丘陵区水土保持综合治理提供依据。
- Abstract:
- There are many evaluation indexes for soil and water conservation. Due to the great differences on natural, social and economic conditions, different evaluation indicators are selected in different regions. Based on the investigation, interviewing, checking local information and consulting experts, we established a three-level evaluation index system including the target layer, the guideline layer and the index layer which totally included 20 indexes. These indexes could quantitatively reflect comprehensive benefit of soil and water conservation in the region. We evaluated comprehensive benefit of soil and water conservation at the area of Dingjiahe via AHP. The result indicated that the score was 0.091 6 for comprehensive benefit of soil and water conservation in the area. The benefits on guideline layer decreased in the order: social benefits > water and soil conservation benefits > ecological benefits > economic benefits. These results were consistent with the local area, indicating that the method was feasible and the index system was reasonable. It could be applied in this area and provide a theoretical basis for comprehensive control of soil and water conservation in the hilly area of eastern Sichuan Basin.
