本文较全面地探讨了除河口地区外,长江水系河水的物理化学条件,计算获得了河水的化学稳定性,酸和碱缓冲容量,表征了河水化学条件的区域分异特征,并对影响河水物理化学条件的因素进行了分析。

The temperature of the water in the Changjiang River System (except the mouth region), as well as DO, pH, COD, total salts, hardness, chemical types, chemical stability, alkali capa-city and acid capacity are studied in this paper.
