摘　　要：下辽河平原南部自上世纪七十年代以来陆续开采了上第三系明化镇组深层地下水,开采至今暴露出一系列的问题,如区域地下水头下降较快形成大面积水头降落、局部出现咸水体扩张及淡水咸化问题,严重威胁该地区居民的淡水资源安全。通过对下辽河平原南部上第三系地下水明化镇组含水层咸水体赋存的地质地貌、补迳排条件、动态特征等进行研究,掌握其赋存条件及分布特征,并提出了防止咸水体进一步扩散的防治措施。The deep groundwater of Neogene Minghuazhen Formations in the southern xiaolioahe plain was exploited in succession since the 1970s.,the Minghuazhen Formations has exposed a series of problems,such as the regional groundwater head down faster form large head landing,local appear salty water body expanding and freshwater salify problem,serious threat to the residents of the area of freshwater resources security.This article is based on study of aquifer salt-water occurrence of geological and geomorphic,filling directly discharge conditions,dynamic characteristic,etc.in the Southern Xialiaohe Plain tertiary groundwater of Minghuazhen.It graspa its occurrence condition and distribution,and puts forward the preventing salty water body proliferation prevention measures.
