摘要: 研究了吉林西部地下水的主要类型及水文地质特征,新构造运动对第四纪环境和地下水赋存的影响,分析了不同地貌区地下水元素地球化学分异性,元素迁移地球化学过程的转化,探讨了潜水埋深、矿化度、组成、径流条件等对内陆盐渍化土壤形成的影响,潜水向上迁移速率与水位的关系,提出了潜水埋深及矿化度与土壤盐渍化程度的定量指标.

Abstract: The salt-affected soil is closely related to groundwater,specially to shallow groundwater with high contains of Na+,HCO3- and larger total mineralization degree in the west of Jilin provience, the upward movement of saline groundwater ant it subsequent evaporation at the suface of the soil adds to the salinization soils.There are different hydrogeologic and geochemical feature in different geomorphic cell affected by Quaternary geology development and Neutecton Movement, the salinization soil types is associated with the different geochemical types of shallow groundwater. The paper analyzed the influence of hydrogeologic and geochemical environment on the soils and the close relationship between salinization soil and shallow table and mineralize degree, and discussed the rate of upward flow relates with the depth to the water table, and the geochemical differentitation in different geomorphic cell,this study offered the quantitative mark between intensity of salinization and water table and mineralization degree.
