摘　　要：为合理开发利用和保护山西省辛安泉岩溶水资源,利用多年观测资料、采样测试成果,结合地下水的补、径、排条件,分析了岩溶水动态变化特征及成因。结果表明:①泉流量在1956~1979年表现为波动状态,主要受降水量影响;在1980~1999年表现为快速下降,主要受降水量、岩溶地下水开采、煤矿开采共同影响;在2000~2019年表现为缓慢下降,主要受岩溶地下水开采和煤矿开采影响。②岩溶地下水水位在1993~2019年总体呈下降趋势,不同位置地下水位变幅有所不同,平顺一壶关、襄垣子系统年均降幅较大,分别为1.02m和0.99m;黎城子系统年均降幅最小,为0.22m。③岩溶水水质总体较好,个别样点水质超标,可能是受矿坑水和地表水渗漏污染影响。In order to rationally develop,utilize and protect the karst water resources of Xin'an Spring of Shanxi Province,the dynamic changes and causes of karst groundwater were analyzed based on observation data of many years,sampling and testing results,and combined with the conditions of groundwater recharge,runoff,and discharge.The results showed that:①From 1956 to 1979,spring flow fluctuated,mainly affected by precipitation,and from 1980 to 1999,it declined rapidly,mainly affected by precipitation,karst groundwater exploitation,and coal mining.From 2000 to 2019,it declined slowly,mainly affected by karst groundwater exploitation and coal mining.②The karst groundwater level showed an overall downward trend from 1993 to 2019,with varying degrees of variation in groundwater levels at different locations.The average annual decrease in the Pingshun—Huguan subsystem and Xiangyuan subsystem were significant,at 1.02 m and 0.99 m,respectively.The average annual decrease of Licheng subsystem was the smallest,at 0.22 m.③The overall quality of karst groundwater was good,with individual points exceeding the standard,which may be affected by leakage pollution of mine water and surface water.
