根据2011年冬季（2月）、春季（5月）、夏季（8月）与秋季（11月）进行的共4个航次的定置刺网渔业资源调查资料，对浙江衢山岛南部近岸水域甲壳动物群落结构特征进行了分析。结果表明：四季共捕获甲壳动物15种，它们隶属于1纲2目9科15属；所有种类中除2种不确定外，其余分别为广温广盐种10种、广温低盐种2种、高温广盐种1种；夏季的重量密度、尾数密度与其余三个季节间均存在极显著差异（P<0.01）；口虾蛄为各季节的共同优势种；丰富度指数（D）与平均表温呈二次曲线相关（P<0.05），重量密度与平均表温呈幂函数曲线相关（P<0.05）。总体而言，春季、夏季与秋季衢山岛南部近岸水域甲壳动物均以广温广盐种为主。

The community characteristics of crustaceans in the coastal water off south Qushan island was analyzed based on the data collected from the investigations in winter(February), spring(May), summer(August) and autumn (November) in 2011 by set gillnets. The results showed that: A total of 15 crustacean species were caught, which belonged to 15 genera, in 9 families, 2 orders, 1 class. For all crustacean species, there were 10 eurythermal and eurysaline species, 2 eurythermal and hyposaline species and 1 hyperthermal and eurysaline species, with ecological type of 2 species uncertain. The weight density in summer was significantly different with that inthe other three seasons(P<0.01), and similar to the individual density(P<0.01). Oratosquilla oratoria was the common dominant species in all four seasons. The relationship between the Margalef richness index ( D) and average surface water temperature can be denoted by binary curve(P<0.05), and the relationship between the weight density and average surface water temperature can be denoted by power function curve (P<0.05). In general, the community of crustaceans in the coastal water off south Qushan island was mainly composed of eurythermal and eurysaline species in spring, summer and autumn.
