湖南书院洲国家湿地公园鱼类资源调查

The investigation in fish resources of Hunan Shuyuanzhou National Wetland Park

通过对湖南书院洲国家湿地公园两个不同断面鱼类进行了连续监测,对其群落组成、生物多样性、优势种组成进行了比较分析。调查发现:有鱼类30种,隶属于5目9科。两个不同生境断面的鱼类小型鱼类均以鲤形目鲤科鱼类为主,且多为小型鱼类。在鱼类的群落结构多样性度量值差异不大:(1)断面Ⅰ鱼类分5目7科22种;断面Ⅱ有鱼类分4目7科19种;(2)断面Ⅰ和断面Ⅱ的多样性指数分别是2.58和2.67,均衡度指数是0.835和1.1,种类相似性指数是53.7%。本次调查还发现湿地公园鲤形目鲤科鱼类新记录5种:分别是银鮈、似鮈、达式鲌、飘鱼和红唇薄鳅。

This paper studied the comparative analysis of fish community composition,biodiversity,and dominant spe-cies composition by monitoring two different sections of fish in Hunan Shuyuanzhou National Wetland Park.The results showed there were a total of 30 species,belong to 5 orders,9 families,and the two different sections were dominant by small fish belong to Cypriniformes and Cyprinidae.The difference in the diversity of fish community structure measure-ment was very small：（1）22 species of fish were collected in section Ⅰ,which were comprised by 5 orders,7 families, and 19 species of fish were collected in section Ⅱ,which was consisted by 4 orders,7 families;（2）The diversity index （H ˊ）of section Ⅰ and section Ⅱ were 2.58 and 2.67,respectively,and the Pielou index （J）were 0.835 and 1.1, respectively.In addition,the category similarity index was 53.7%.In this survey we found 5 new record species Squali-dus argentatus,Pseudogobio vaillanti,Erythroculter dabryi,Pseudolaubuca sinensis and Leptobotia rubrilaris,which were all belong to Cypriniformes.
