摘　　要： 通过分析研究中山市高平镇洪奇沥潮间带的底栖动物的种类、生物量、优势度等各种生态指标得出该河道水体污染达到较轻的富营养化水平。并从底质、水体有机物等方面分析了污染原因,根据实际情况提出了对策和建议。 The water pollution can be detected by using the species composition,density and construction of zoobenthos. The species composition,biomass,dominance and the ecological indexes of zoobenthos in the intertidal zones in Gaoping Hongqili in Zhongshan city were investigated and studied. The results showed that the water quality of the intertidal zone were belonged to mesotrophic type. The rea- sons were analyzed from the aspects of sediment and organisms in water in the sampling areas and some suggestions were proposed in this paper.
