摘　　要：本文利用生态位理论，对水磨河6个站点，讨论了14个优势种的群落结构与水体污染之间的关系，在r—k连续统中进行种的生态位排序，通过聚类分析绘出底栖动物群落树状图，将水磨河底栖动物群落分成四个集群类型和一个边缘种，并叙述了其污染生态学特性和生态对策。By using niche analysis for 14 dominant species at the six station in Shuimo River,Urumqi, the reationships between community structure and water pollution were discussed.The niche ordinahon from the overlap matrix resulted in a r-k continuum of successional gradients, and based on it the commnity dendrogram was also made by cluster analysis.The commnity was separated into four guilds and one fringe species. The author described the polluted characteristies of each guilds of benthic animals and ecological strategy of successional species.
