    摘要:

    依据山西省自然地理及经济发展状况,从自然、人为、承载力等三方面影响水资源脆弱性的因素中选取8个指标构建水资源脆弱性评价体系,运用基于熵权的模糊集对法对山西省11个地级市2012—2018年水资源脆弱性进行评价,并比较了模糊综合法、灰关联分析法和基于熵权的模糊集对法3种方法2018年的评价结果。结果表明,山西省存在用水效率较低、地下水超采、水污染、水土流失等主要问题,整体水资源脆弱性属于比较脆弱和严重脆弱等级;提出通过调整产业结构、优化配置水资源、提高污废水回收利用率、恢复植被等对策改善山西省水资源脆弱性状况。

    Abstract:

    According to the physical geography condition and economic development situation of Shanxi Province, water resources vulnerability assessment system was established from eight indexes based on three factors which could affect water resources vulnerability including natural, human and bearing capacity factors. The water resources vulnerability of 11 administrative cities in Shanxi Province from 2012 to 2018 were evaluated by entropy weight based fuzzy set pair method. The assessment results of fuzzy comprehensive method, grey relational analysis method and entropy weight based fuzzy set pair method were compared in 2018. The results indicate that Shanxi Province has the main problems of low water efficiency, groundwater overexploitation, water pollution, and soil erosion. The whole water resources vulnerability is at relatively fragile and serious fragile level. Its proposed that adjusting industrial structure, optimizing allocation of water resources, increasing the reclamation rate of wastewater and restoring vegetation could improve the water resources vulnerability condition of Shanxi Province.
