| 摘 要： | 2009年6、11月和2010年4月共3个水情期（即丰、枯和平水期）对赣江流域一级支流袁河底栖动物群落结构进行了调查。结果表明袁河流域底栖动物17种,隶属于3门5纲12科,其中寡毛类4种,蛭类1种,腹足类5种,瓣鳃类4种,水生昆虫类3种。袁河底栖动物3期总密度和总生物量分别为1 762.29 ind./m2和982.37 g/m2,密度上摇蚊占优势,生物量上铜锈环棱螺占优势。不同水情期现存量也存在差异,平水期的密度和生物量均比丰水期、枯水期的大;丰水期的密度比枯水期的大,而生物量却比枯水期的小。袁河底栖动物优势种为摇蚊、铜锈环棱螺、河蚬和方格短沟蜷。Shannon-Wiener指数、Margalef指数表明袁河底栖动物多样性存在季节性变化,且下游多样性比上中游复杂;Shannon-Wiener指数和FBI指数的结果表明袁河水质已受到不同程度污染。

| Abstract: | The community structure of macrozoobenthos in Yuanhe River which was a first level tributary of Ganjiang River basin were investigated in June 2009,November 2009 and April 2010 for the high-water period,low-water period and normal-water period respectively.The results showed that 17 species of macrozoobenthos were identified,belonged to 3 phyla,5 classes and 12 families,were identified.There were 4 species of Oligochaeta,1 species of Hirudinca,5 species of Gastropoda,4 species of Lamellibramchia,and 13 spec... |
