Geochemical Mechanisms Controlling Basic Chemical Compositions of Lake Water Mass

This paper discusses main mechanisms contrilling or affacting chemical compositions of lake water mass such as atomsphere precipitation,sediment and water interaction,biological process,soil chemical weathering,crystal zation and evaporation within the lake,describes some methods of source analysis of some chemical components in lake water,and presents some typical problems in environ-mental geochemistry in lakes to be needed to study in the further.
