摘　　要：针对宿州市城西水源地由于长期开采地下水、井位布局不合理,且地下水补给有限,已严重超采,形成了若干个地下水水位降落漏斗,直接威胁城区供水安全的现实,通过数值模拟法计算宿州市城西水源地的地下水可开采量,采用开采系数法对水源地进行地下水超采评价,并制定相应的限采方案,预测限采后地下水水位的变化,分析限采效果。结果表明,现状年2010年城西水源地地下水开采系数为1.30,属于严重超采;实施限采方案后,规划年2015年、2020年,地下水开采系数分别为1.21、0.97,限采效果较明显。Because of the long-term exploitation, unreasonable distribution of pumping wells and limited groundwater recharge, Chengxi well field in Suzhou City was over-drafted seriously and formed several cones of depression, threatening the safety of water supply directly. Allowable groundwater withdrawal of Chengxi well field in Suzhou City was calculated through numerical simulation method, and then the overexploitafion situation was evaluated based on the exploitation coefficient method, to formulate the limited pumping scheme, predict the groundwater level after conducting the scheme, and analyze the recovery effect. The results showed that, in the year of 2010, the exploitation coefficient of Chengxi well field was 1.30, and the well field was overexploited seriously. After the implementation of limited pumping scheme, in the year of 2015 and 2020, the exploitation coefficient would be 1.21 and 0. 97 respectively, showing the effect of pumping-limit scheme would be significant.
