系统研究了吉林省境内松花江、辽河、图们江、鸭绿江、绥芬河等 5大水系河源区地表水地球化学特征 ,并以中部大黑山为界分东部山地和西部平原两大地貌单元对其地域差异进行比较。探讨了 K、Na、Ca、Mg、Cu、Zn、Fe、Mn等 16种元素的分布特征 ,并对 p H、Eh、溶解氧等主要影响因素进行了分析。为河源区水资源保护及退化机理研究奠定了基础。
The geochemical characteristics of surface water in the Heyuan area of Songhua River, Liaohe River, Tumen River, Yalu River and Suifenhe River in Jilin Province were systematically studied. The geomorphic characteristics of surface water in the Heyuan area of the five major river systems, including the eastern mountainous area and the western plain, Differences are compared. The distribution characteristics of 16 elements such as K, Na, Ca, Mg, Cu, Zn, Fe and Mn were discussed. The main influencing factors such as p H, Eh and dissolved oxygen were also analyzed. Laying a foundation for the study of water resources protection and degradation mechanism in Heyuan area.
