摘要： 本文根据黄河流域69个水化学测站500个站年资料分析了水化学特征及其区域分异。

Abstract: The paper dealing with water quality analysis is based on long series of data which consists of 69 representative hydrochemistry stations in the Huanghe Basin.These statistical data in eludes 500 station-years.The component and pattern of natural hydrochemistry in the Huanghe Basin are rather complex. The mineralization degree of river water varies from 200 to 5000 mg/L, the mineralization degree of river water in upper and lower reaches is adequate, but the characterastics of water quality (mineralization degree, total hardness and main ions) have obvious zonal distribution in its middle reaches, and they basically conform with natural conditions and distribution trend of water and heat.

Key words: mineralization degree, total hardness, total alkalization degree, main ions
