| 摘 要： | 雷州半岛地表水资源缺乏 ,地下水资源较丰富 ,近年开采量剧增 ,局部已形成大面积降落漏斗 ,面临海水入侵的威胁。通过对研究区内地下水流的数值模拟 ,建立了一个以预防海水入侵为目的的地下水资源管理模型 ,并以管理区为单元给出了不同区域地下水资源的最优开采量。认为在防止海水入侵的前提下 ,区内地下水总体上尚有开采潜力 ,但要适当分散开采区域 ,滨岸地区基本维持现状 ,内陆可不同程度地增大开采量。

| Abstract: | The groundwater resources are abundant while surface water resources are relatively poor in the Leizhou Peninsula. In recent years, with the rapid increase in the groundwater exploitation, the regional depression cones have being occurred in some coastal areas. Cities near the coast are facing the threat of seawater intrusion due to groundwater overexploitation. Based on numerical simulation of the groundwater system, a groundwater resource management model has been established to prevent seawater intrusion. Optimal groundwater withdrawal rates were obtained for every management cells in this area. It is indicated that the groundwater could be exploited in a scattered well pattern. The recent withdrawal may be maintained in the coastal area and increased to some extent in the inland area. |
