A Study on the Aquatic Environment in Dongguan Reach of the Dongjiang River

东江是珠江水系的主要干流之一 ,是广东东部至关重要的水系 ,文中详细分析了东江东莞段 90年代中后期的水质状况 ,在此基础上研究和探讨了东江东莞段水质的季节变化规律及其水质变化趋势。

The Dongjiang River,as one of main streams of the Pearl River system,is the important water system in eastern Guangdong Province.This paper analyzes the water quality of Dongguan Reach in the Dongjiang River in mid and late 1990 (1994～1999) and,on the basis of this,studies the rule of seasonal change of the water quality and discusses the developing tendency of the water quailty.
