摘　　要： 在广州市南沙区水域采集地表水和水生生物样品,对水质主要理化指标、叶绿素a含量和初级生产力以及水生生物(浮游植物和浮游动物)的种类、数量、多样性和均匀度指数等进行调查,综合评价了南沙区水域水生生态环境质量。结果表明,利用不同指标对南沙区水域进行评价获得的结果基本一致,介于贫营养化至中营养化状态之间,水生生态环境质量状况较好。 Surface water and hydrobiontes in Nansha district were sampled to investigate and assess the current status of aquatic eeo-environment in Nansha district. The physicoehemieal characteristics, the chlorophyll a and primary productivity of surface water were determined and the type, number, diversity and evenness index of hydrohiontes （phytoplankton and zooplankton） were studied. Consistent evaluation results were obtained from these indicators. Results showed that aquatic eco-environment of Nansha district was good; it was in the stage of oligotrophication to mid-eutrophication.
