摘　　要：在分析内蒙古自治区通辽市南部地区的水文地质情况的基础上,利用航空电磁法在该区的实测结果及数据转换结果,推断了水质分布特征,圈定了土壤盐渍化范围。结果表明:研究区内重盐渍化地区极少,多为非盐渍化区;北部平原区的地下水资源较丰富,其第四系含水层是一个具有自由水面且相互连通的地下水的巨大赋存空间。Based on an analysis of hydrogelogical conditions in southern Tongliao of Inner Mongolia, the authors inferred the distribu- tion characteristics of the water quality and delineated the limits of soil salinization by using the airborne electromagnetic method （ AEM ） and the results of data conversion. The results of AEM exploration indicate that the re-salinized area is very insignificantI whereas the non-salinizati0n area is very extensive; the groundwater resources of the northern plain area are rich and the Quaternary aquifer is a huge hosting space of interconnected groundwater with free surface.
