摘　　要：采用水质综合标识指数法对东江惠州段2011年全年水质污染特征进行分析。结果表明,东江干流惠州段各断面水质基本达标,支流西枝江以及淡水河污染严重;空间分布上东江干流惠州段水质从上游到下游呈下降趋势,时间分布上干流水质丰水期比枯水期污染严重,而支流在枯水期污染严重;NH4+-N是东江惠州段的主要特征污染物,点源是主要污染来源,在此基础上提出相关污染防治建议。The water quality of Dongjiang River in Huizhou was evaluated by comprehensive water quality identification index in the year of 2011. Results showed that water quality of the mainstream reached the standard,and water of Xizhijiang River and Danshui River were seriously polluted. The water quality decreased from the upper to the lower mainstream. In comparison of dry season,water quality of the mainstream of the River was more severely contaminated in flood season.However,the tributary was the opposite. The point sources of pollution were the main source of pollution in which ammonia nitrogen was the characteristic pollutant in the River. Based on the results,some comprehensive countermeasures would be proposed to protect the water environment.
