摘　　要：从水质、沉积物、生物3个层次,分析永定新河河口周围水域环境质量现状,对水质进行有机污染评价,有些站位甚至出现重度污染。同时对沉积物进行单因子评价,沉积物质量状况较好。采用生物多样性指数法分析浮游植物、浮游动物和底栖生物,生物生存环境较差,底栖生物的尤其明显。The status quo of environmental quality around the outlet of Yongding New River was analyzed from three layers,namely water quality,sediment and creatures.The organic pollution was evaluated and it was concluded that there even exists severe pollution.The quality of sediment is good using single factor index method.The biological living environment of plankton,benthon and hydophyte were analyzed via biological diversity index,and it was concluded that biological habitat is poor especially benthos.
