摘要
简述汉江水质总体优于长江水质这一自然现象，分析产生这一现象的原因。认为其原因极可能是由两江的地质构造、土壤化学成份、河道坡度、河面宽度等的不同而引起。人类可用环境水利工程改造河流，使河流自然地为人类“制造”洁净饮水，从而克服现有净化处理技术在净化微污染水方面的局限。
In this article,the author discusses the reason why water quality of the Hanjiang River is better than that of the Yangtze River. It is shown that it is because of the differences of geological structures,soil constitution,riverside slopes and river widths,and so on. The author suggests that environment-hydaulic engineering projects should be constructed to regulate rivers, so water in the river will naturally be clear and the limitation of the water purification technology for slight-polluted water process can be conquered.
