摘　　要：分别对太湖流域苏锡常地区、杭嘉湖地区及上海市的地下水现状进行详细分析。指出,由于苏锡常地区从20世纪80年代开始超采地下水,逐步形成了以苏锡常3市为中心的大型地下水水位降落漏斗,深达80m,面积广达5483km2;杭嘉湖地区有漏斗区8个;上海市开采井深已达200m左右。基本划定3个地区的地面沉降范围和沉降值,并分别针对上述地区的不同地质条件,提出地下水资源保护的对策与措施。The present situation of the groundwater of the Taihu Lake Basin is expounded in detail. The groundwater quality is analyzed for the Suzhou Wuxi Changzhou region, the Hangjiahu region and Shanghai City. It is pointed out that the overmining of groundwater in the Suzhou Wuxi Changzhou region since 1980 has resulted in the formation of large depression cones centered at the three cities, the depth of them reaching 80?m, and the total area being above 5?483?km 2. Analysis also shows that there are 8 cone regions in the Hangjiahu region, and that the number of wells for groundwater mining in Shanghai City reaches 200. Furthermore, the range and amount of the groundwater mining induced ground settlement of the above three regions are classified, and countermeasures for protection of the groundwater of the regions are proposed based on their different geological conditions.
