| 摘 要： | 针对中国一些沿海地区地下水超采及由此带来的海水入侵问题,将地表水补给、抽水量及地下水位等相嵌在一起,建立了沿海地区地下水模拟优化管理模型。将人工鱼群算法和基于MODFLOW2000的变密度地下水流及溶质运移模型耦合起来,对沿海地区地下水模拟优化管理模型进行求解。以山东省威海市节水示范区为例,验证模型的有效性和可靠性。结果表明,10、11、12月份抽水量最大,以后至第2年5月份依次是减少的;从区域分布上看,在临海区域1号井处抽水量是3500～1120m3/月,在其它井处是6540～2920m3/月;与现行方案相比,增加总有效供水1990m3,地下水平均水位升高0.29m,海水入侵问题能够得到解决。计算结果合理可行,为沿海地区地下水资源的科学管理和持续利用提供可靠依据。

| Abstract: | To counter the issues of groundwater overdraft and seawater intrusion,a smiulation-optimization model,coupled with recharge,pumpage and groundwater level,is established for the optimization groundwater management.The artificial fish-swarm algorithm is coupled with MODFLOW 2000,which is used to solve the management model.The management model is used in water saving irrigation region,Weihai city,Shandong province,to demonstrate the effectiveness and robustness of the management model. The result shows that the amount of groundwater pumpage reaches maxmium during October through December.From the point of maxmium,there will be a reduction in the pumping activity until next May.It is found that the permissible pumpage ranges from 3500 to 1120m3/month at well 1 in the coastal area,and 6540 to 2920m3/month in the non-coastal area.Comparing to the current plan for g roundwater operation,there will be increases in the total effective water supply of 1990 m3 and in the groundwater level of 0.29 m.The result is reasonable and feasible.The management model is applicable for optimizing groundwater management strategies in coastal areas. |
