枣庄市地下水动态变化特征研究

Study on Groundwater Regime Characteristics in Zaozhuang City

枣庄市以岩溶地下水为主要供水水源,多年的超采造成了十里泉及丁庄主要岩溶水源地下水水位大幅度下降,并诱发了地下水污染、岩溶地面塌陷等严重的环境地质问题。根据枣庄市岩溶地下水21年的监测资料,揭示了枣庄市岩溶地下水水位动态特征。岩溶地下水水位呈现季节性和多年变化特征,其中,岩溶地下水水位季节性变化特征与降水量密切相关,多年水位变化受降水和开采量的综合作用的影响。

Karst water is the main water resource for Zaozhuang city. During the past decades, overdraft of groundwater has caused large depression cones of groundwater and induced serious geo - environmental problems such as groundwater pollution, karst collal^se and so on. Based on the monitoring data of twenty - one years, groundwater regime of karst water which had seasonal and perennial variation characteristics in Zaozhuang city had been presented. The seasonal variation characteristics were mainly caused by precipitation. Consequently, the lowest groundwater level appeared in May or June, and the highest appeared from August to September. The perennial variation of groundwater regime was influenced by both exploitation of groundwater and precipitation. Before 1997, the groundwater level dropped down continuously and it rose slowly after 1998. Finally, some countermeasures for the sustainable utilization of karst water resource of Zaozhuang city like protection of existing karst water source and exploitation of new karst water source were put forward in detail.
