| 【目的】建立基于改进模糊物元的水安全评价模型，为有效评价区域水安全状况提供支持。【方法】建立基于熵权的改进模糊物元模型，选取人均水资源量、单位面积水资源量、地表水利用程度、地下水利用程度、工业万元增加值用水量、农业用水综合定额、人均用水量、工业废水处理达标排放率、Ⅳ级以上水质级别占总河长比例、洪水受灾面积率、干旱受灾面积率、单位面积蓄水工程总库容、堤防保护耕地面积率、灌溉面积率等14项评价指标，对山西省太原、大同、阳泉、长治、晋城、朔州、忻州、吕梁、晋中、临汾、运城等11个地区的水安全进行评价。【结果】采用基于熵权的改进模糊物元模型对山西省水安全状况的评价结果表明，山西省属于水不安全地区，综合评价等级值为 1.950 3；晋中市、阳泉市、长治市、忻州市和晋城市属临界安全地区，综合评价等级值分别为2.178 9，2.138 1，2.121 1，2.102 4和2.088 2；太原市、运城市、吕梁市、临汾市、朔州市和大同市属于不安全地区，综合评价等级值分别为1.869 1，1.825 9，1.816 9，1.796 2，1.769 7和1.746 3。【结论】建立的基于熵权的改进模糊物元模型的水安全评价结果与当地水资源实际状况基本相符，可为区域水资源开发利用提供指导。 |

| Abstract: |
| 【Objective】This study proposed an improved fuzzy matter-element model to support the effective evaluation of regional water safety.【Method】A total of 14 indicators including per capita water resources,water resources per unit area,surface water level,groundwater utilization degree,million yuan of industrial added value of water,agricultural water quota,comprehensive water use per capita,industrial wastewater discharge rate,ratio of water with level Ⅳ and above,ratio of flooded area,ratio of drought area,water storage per unit area of storage projects,ratio of embankment protected cultivated land,and ratio of irrigation area were selected to evaluate water safety in Taiyuan,Datong,Yangquan,Changzhi,Jincheng,Shuozhou,Xinzhou,Lüliang,Jinzhong,Linfen,and Yuncheng in Shanxi province.【Result】Based on the improved fuzzy matter-element model,water effective evaluation showed that Shanxi province was unsafe for water utilization with comprehensive evaluation value of 1.950 3.Jinzhong,Yangquan,Changzhi,Xinzhou and Jincheng belonged to critical safety areas with comprehensive evaluation values of 2.178 9,2.138 1,2.121 1,2.102 4 and 2.088 2,respectively.Taiyuan,Yuncheng,Lüliang,Linfen,Shuozhou and Datong belonged to unsafe areas with comprehensive evaluation values of 1.869 1,1.825 9,1.816 9,1.796 2,1.769 7 and 1.746 3,respectively.【Conclusion】The improved fuzzy matter-element model based water effective evaluation was generally consistent with the water resources status.The model can provide guidance for development and utilization of regional water resources. |
