水利风景资源评价指标体系构建与实证研究——以陕西省为例

基于层次分析法和模糊评价法构建水利风景资源评价指标体系,系统阐述了评价指标的选取、层次结构模型的构建、指标的权重赋值以及资源分级评价的方法,并以陕西省为例,对水利风景资源评价指标体系的适用性和合理性进行实证研究.结果显示,资源价值指标权重为0.54,开发条件指标权重为0.30,生态环境指标权重为0.16,观赏价值、游憩价值、区位条件、文化价值、交通条件、水环境质量等6项指标为最重要因子;地区发展、水土保持质量、科学价值、资源稀缺性、生态环境质量等5项指标为较重要因子;设施建设、资源组合性、规模与丰度、知名度、环境容量、适游程度、管理水平等7项指标为一般重要因子.

Construction and Empirical Research on Evaluation Index System of Water Scenery Resources--A Case Study of Shaanxi Province

Using AHP method and fuzzy evaluation method to build the evaluation index system of water sceneryresources. The paper describes the selection of evaluation index,the construction of hierarchical model,theassignment of index weights and the classification of water scenery resources. Research results show that the weightof resource value index is 0.54,the weight of development conditions index 0.30,and the weight of ecologicalenvironment index 0.16. A case study of 43 representative water scenery resources in Shaanxi Province is used tovalidate the rationality and applicability of the evaluation index system.
