Based on the detailed water quality monitoring data of about 317 hydrometric stations from 1960 to 2000 and water quantity data of 20 hydrometric stations between 1919 and 2000 included in the Hydrological Yearbooks, which were all published by Yellow River Conservancy Commission, and socio-economic data related to the Yellow River, the characteristics of water quantity, major ion chemistry, organic contamination and their mechanisms, and integrated watershed management issues of the Yellow River have been systematically studied in this work.

本文在全面分析黄河流域300余水文站过去40年（1960—2000）水质资料和干支流20余水文站过去近50年（1950—2000）径流量资料的基础上，研究了：（1）、黄河水量的基本特征和近40年来的变化，重点讨论了黄河下游&断流&现象的发展及原因：（2）、黄河天然水质的基本特征、区域分布和影响因素；（3）、黄河天然水质40年来的变化趋势及原因；（4）、黄河水系氮污染和有机污染的特征、近40年来的发展，及其与社会经济发展的关系；（5）、黄河下游水质变化与水量变化的关系；以及，（6）、黄河水质水量管理中的制度安排问题。

This hollow ball not only has the function of adsorption filtration depuration of water but also reduce the acidity of water to activation decomposition lessening of hydrone through piezoelectricity and activation of releasing negative ion and sending far infrared. These processes can balance people's PH and make water tasted well and became alkalescence.
