摘　　要：近些年兰村泉域乃至山西省施行关井压采等一系列政策之后,兰村泉域水位呈现上升趋势,地下水动态类型发生新的变化,大气降雨作为其中的一个重要因素起着关键性作用。以兰村泉域为例,通过运用spss以及相关性分析方法等手段,研究降雨与不同类型岩溶区地下水动态的关系。结果显示:降雨与裸露型岩溶区地下水成中度正相关,滞后时间约2个月;与覆盖型岩溶区地下水成滞后性正相关,相关性较弱,滞后时间约为4个月;与埋藏型岩溶区地下水成低度正相关,滞后时间约为6个月。通过此次研究帮助我们了解兰村泉域最新的地下水动态,提高兰村泉域的研究精度,为兰村泉域地下水管理提供科学的数据支撑。In recent years, a series of policies have been adopted in the Lancun spring area and even in Shanxi Province, where the water level of the Lancun spring area has been on the rise and new changes have taken place in the dynamic types of the groundwater. Rainfall in the atmosphere is one of the key factors effect. Taking Lancun spring area as an example, the re- lationship between rainfall and the groundwater dynamics in different types of karst areas was analyzed through the use of spss and correlation methods. The results show that there is a positive correlation between rainfall and groundwater in bare karst are- a with a lag time of about 2 months, a positive correlation with groundwater in cover karst area, and a weak correlation with a lag time of about 4 months. Karst groundwater into a low degree of positive correlation, the lag time is about 6 months. Through this study, we can help us to understand the latest groundwater dynamics in Lancun spring area, improve the research precision in Lancun spring area, and provide scientific data support for Lancun spring area groundwater management.
