摘要: 为了解浙江省大陈洋产卵场保护区甲壳类的群落结构特征,于2018年春季(4月)和秋季(11月)对甲壳类生物资源进行了底拖网调查,应用相对重要性指数(IRI)、生物多样性指数和典范对应分析(CCA)等方法对其群落结构及其与环境因子的关系进行了综合分析。结果表明: 共鉴定出甲壳类38种,隶属14科25属,其中口虾蛄、三疣梭子蟹、双斑蟳和哈氏仿对虾为优势种。春季甲壳类资源密度在50 m以浅海域较高;秋季在50 m以深海域较高,且保护区内南部甲壳类资源密度高于北部。关于多样性特征,春季甲壳类丰富度指数(D)、多样性指数(H)和均匀度指数(J)均高于秋季,空间分布上50 m以深海域甲壳类的H最高。根据生物量进行等级聚类分析(CLUSTER)和非度量多维标度排序(NMDS)分析,春季可将甲壳类划分为3个群落,秋季划分为4个群落,春季甲壳类群落结构组内差异性较秋季显著。典范对应分析结果表明,水深、底温、盐度和溶解氧为影响甲壳类种类组成和时空变化的主要环境因子。

Abstract: To elucidate the characteristics of fishery resources structure in the Dachenyang Spaw-ning Ground Reserve, the index of relative importance (IRI), biodiversity index and canonical correspondence analysis (CCA) were used to explore the relationship between crustaceans community and marine environment based on the bottom trawl survey data collected from April and November in 2018. A total of 38 crustaceans species were recorded, belonged to 25 genera in 14 families. The dominant species were Oratosquilla oratoria, Portunus trituberculatus, Charybdis bimaculata, and Parapenaeopsis hardwickii. The resource density of crustaceans was generally high in depths below 50 m in spring and in depths above 50 m in autumn. The density in the southern area was higher than nouthern area. The Margalef species richness index (D), Shannon diversity index (H) and Pielou evenness index (J) of crustaceans in spring was higher than that in autumn. The H of crustaceans in depths above 50 m was the highest. Based on cluster analysis and non-matrix multidimentional scaling analysis, the crustaceans could be classified into three groups in spring and four groups in autumn. The differences in crustacean community structure in spring were more significant than in autumn. The results of canonical correspondence analysis (CCA) showed that water depth, bottom temperature, salinity and dissolved oxygen were the main environmental factors affecting species composition and spatial structure of crustaceans in the surveyed area.
