摘  要:
根据2016年5、10月在琼州海峡进行底拖网生物资源调查所获得的22个站位资料,分析了琼州海峡虾类种类组成、优势种、生物多样性、群落结构的相似性、相异性等群落结构特征。结果表明,调查样品共鉴定出虾类19种,隶属于6科13属,其中优势种为葛氏长臂虾和哈氏仿对虾2种。分布在水深小于20 m区域的虾类种数最多,随水深增加虾类种类数呈递减趋势。丰富度指数(D)、均匀度指数(J')和多样性指数(H')秋季均高于春季。凡纳滨对虾和周氏新对虾对春季群落结构影响较大,哈氏仿对虾对秋季群落结构影响较大。

摘  要:
Based on the data acquired use bottom trawl in seasonal comprehensive surveys of 22 marine ecosystem of Qiongzhou strait in May and October,2016,the species composition,dominant species and diver-sity of shrimp were analyzed.Quantitative analysis was used to identify the similarity and dissimilarity of com-munity structure.A total of 19 species were identified,which belonged to 13 generas in 6 families.Parapenaeopsis hardwickii and Palaemon gravieri were the dominant species.The shrimp species had the highest diversity in the water(depth less than 20 m).With the increase of the depth,the shrimp species showed a declin-ing trend.The richness index(D),evenness index(J') and diversity index(H') in autumn were higher than in spring.Litopenaeus vannamei and Metapenaeus joyneri showed significant influence on the spring community structure,while P.hardwickii showed great influence on the spring community structure.
