摘　　要：晋祠泉域岩溶水是太原市生活和工农业生产等重要的水源。文章以新划分的晋祠泉域岩溶水系统为评价对象,在欧洲方法及“水量脆弱性评价”的基础上,选取包气带厚度、入渗补给强度、上覆地层岩性及岩溶含水层的富水性4个指标,进行泉域岩溶水系统防污性能评价及水质保护区划分。结果表明:泉域泉源保护区主要分布在晋祠公园及周边;一级保护区主要分布在汾河主干流、西山山前碳酸盐岩裸露区,屯兰川、天池河及柳林河碳酸盐岩渗漏段等;二级保护区主要分布在泉域北部、汾河北岸等;准保护区主要分布在汾河南岸、东南部的太原盆地地区等。Jinci spring is a famous karst spring in Shanxi Province,and its backflow is an ecological restoration goal of the Shanxi Provincial government.Composed of Nanlao spring,Shengmu spring,and Shanli spring,Jinci spring is exposed at the foot of Xuanweng mountain in the western mountains of Taiyuan,twenty-five kilometers away from the city center,and it is a concentrated discharge point for karst water in the Jinci spring area.Karst water in the spring area is mainly supplied by atmospheric precipitation infiltration and leakage from rivers and reservoirs.Karst water in the Jinci spring area is an important water source for people's life and industrial and agricultural production in Taiyuan City.In recent years,with the intensification of climate change,large-scale development of karst water,coal mining and other human activities,especially after the construction of the second reservoir of the Fenhe river,the karst hydrogeological conditions in the spring area have undergone fundamental changes,with the spring area expanding from 2,030 km2 to 2,713 km2,which has affected the evaluation,management and protection of karst water resources in the spring area.The original zoning of protected areas can no longer meet the needs of water resource management and protection.Therefore,it is urgent to re-zone the protected areas and formulate corresponding protection measures.In terms of the problems on water quality and quantity,there exist differences in the causes,regions,and protective measures,and thus LIANG Yongping et al.proposed the concepts of"water quantity vulnerability"and"water quality vulnerability",as well as a method of"first classifying,and then grading"for the zoning of karst aquifer protected areas.This study focuses on the hydrogeological conditions of special recharge,runoff,and discharge in the karst water system of North China,as well as the main influencing factors of the antifouling performance of karst aquifer systems.It combines European methods and"water vulnerability assessment"to evaluate the antifo
