摘　　要：吉林省松辽平原东部高平原第四系孔隙地下水由于缺少良好的含水层而比较贫乏。白垩系基岩孔隙裂隙水就成了本区地下水主要的供水开采层。在简要阐述白垩系区域水文地质条件的基础上,分析白垩系地下水水化学特征及其水化学成分在水平和垂直方向上的变化规律,从水质方面为地下水合理开发提供科学依据。There are a large population and close economic active area in the high east plain of Songliao plain, Jilin Province. The short of water resources is one of the main restrictive factors all the time for the economic and social development. Owing to the short of the Quaternary pore-space water, the Cretaceous bedrock fissured water forms a mainaquifer in this area. On the basis of the Cretaceous regional hydrogeological condition, analyzed hydrochemical characteristics of the Cretaceous ground water and change regularities of water chemical composition in horizontal and vertical directions. It provided a scientific basis for the reasonable development of ground water in water quality.
