摘　　要：根据2004～2007年8月象山港乌沙山电厂附近海域底栖生物的调查资料，对该海域底栖生物的种类组成、数量分布、生态群落多样性及其变化趋势进行了研究。结果表明，电厂附近海域底栖生物种类贫乏，栖息密度和生物量均较低，尤其是电厂试运行后，该海域底栖生物种类、数量均明显降低，优势种亦发生了明显变化；生物多样性指数、丰富度、均匀度较低，且呈明显下降趋势，底栖群落结构已相当脆弱和不稳定。这表明电厂附近海域底栖生态系统已受到明显扰动。Basted upon the investigation data from Aug. 2004 to Aug. 2007, the specific composition, the distribution of quantities and the diversity of ecological community including some changes of benthos in the seaarea near the WuSha Mountain Power Station were studied. The results showed that the species was poor and the biomass, the inhabited density were lower, and that the species, the biomass and the inhabited density of benthos were obviously failed and the donimant species was markedly changed especially after the test run of the Power Sstation. It was also showed that the diversity index, the abundance and the uniformity were lower and obvi- ously reduced. The benthic community near the Power Station was very frlal and unstable. Therefor, it showed that the ecosystem of benthos in the region where the power station was buihed,has been disturbed.
