西南岩溶山区碳酸盐岩布露广泛,岩溶发育较强烈,强烈的岩溶化作用形成地表、地下双层空间结构,造成区域水资源分布极不均衡。在对岩溶山区水文地质、社会经济以及区域环境的相关资料进行研究的基础上,从地下水资源条件、地下水资源开发利用条件、社会经济条件、生态环境条件4个方面出发,选取了28项指标,同时结合模糊层次分析方法探讨一种岩溶山区地下水可持续指标评价体系及评价方法,以贵州威宁地区为实例,对该地区地下水资源可持续性进行了评价,评价效果较好。
Abstract
Carbonate rocks are widely distributed in the karst mountain area of southwest China. Because of the intensively developed karst ecological degeneration, the water resource distribution in this region is seriously imbalanced. On the basis of hydrogeology, social economy and regional environment data, 28 indicators were selected from four aspects groundwater resource condition, development and utilization of groundwater resource, social economy, and ecological environment to establish an assessment system for groundwater resource sustainability in karst mountain area. Meanwhile, the weights of the indicators based on fuzzy analytical hierarchy process(FAHP) were determined, which reduced the fuzziness of man-made judgments. The sustainability of groundwater resource was evaluated taking Weining area of Guizhou province as an illustration.
