摘　　要：利用综合营养状态指数评价东江富营养化状况。结果表明,东江富营养化程度较轻,干流绝大部分区域(96%)为中营养及中营养以下水平,只有少数区域(4%)达到富营养水平。同时,东江干流富营养化程度区域差异性明显,从上游至下游河口富营养化程度逐渐加重。针对东江水质污染现状,建议东江水体管理应以保护为主,同时采取有效措施,改善下游部分区域污染严重的现状。The eutrophication state in Dongjiang was comprehensively evaluated by using trophic status indices.Results showed that the eutrophocation status of Dongjiang was in a low level for 96% of mainstream water was between oligotrophic and mesotrophic,only 4% of mainstream water reached the eutrophication.Furthermore,the eutrophication state in Dongjiang mainstream presented obvious regional differences;the degree of eutrophication becomes deepen from upstream to estuaries.Base on actual pollution condition of Dongjiang,the water management should be give prominence to the water protection;meanwhile some effective measures should be taken to improve water quality in serious polluted areas of downstream.
