摘  要：
根据2006年6、8、10月长江口及邻近海域缺氧区底拖网定点捕捞调查资料,分析了长江口及邻近海域大型无脊椎动物群落结构组成及数量分布。结果表明,长江口大型无脊椎动物种类共49种,隶属2纲5目25科37属;生物量组成以蟹类为主,占大型无脊椎动物总生物量的58.20%;个体数密度组成以虾类为主,占大型无脊椎动物总密度的92.41%;不同航次大型无脊椎动物生物量分布变化较大,个体数密度分布与水温、盐度、水深、pH及溶解氧等单因子相关性均不显著,但受水温及盐度影响相对较大。

Changjiang River estuary Macroinvertebrate Distribution Environmental factors
摘  要：
Based on the data from bottom trawl surveys in June, August,and October, 2006, the structure and distribution of macroinvertebrate resources in the Changjiang River estuary and its adjacent waters were analyzed. Totally 49 species of macroinvertebrate were caught, belonging to 2 classes, 5 orders, 25 families, and 37 genus. Crabs accounted for 58.20% in biomass, and shrimps accounted for 92.41% in individual number. Biomass distribution of macroinvertebrate differed by survey time. The relationship was not significant between the density distribution and single environmental factor, such as water temperature, salinity, water depth, pH, dissolved oxygen etc. Relatively, water temperature and salinity have more influence on the density distribution of macroinvertebrate than other environmental factors.
