摘要： 对我国四大水系-长江、黄河、松花江和珠江50年代末至80年代中期河水中主要离子含量与流域降水量、区域地质岩性等自然条件进行了统计研究.研究表明:区域地质岩性对河水离子含量和组成有显著影响;河水离子总量与相应区域的降水量存在显著负相关关系.

Abstract: According to major ion content data of the Yangtze River, Yellow River, Songhua River and Preal River systems from 1959 to 1985, regional rainfall data and lithology data, the relationship between the characteristics of major ion chemistry and natural factors such as regional climate and lithology has been analyzed through statistics methods. The conclusions reached are as follows. The ion content of river water and the composition of river water are remarkably controlled by rational rock dissolution. The total ion contents of river water are remarkably negatively correlated with regional rainfall.
