| 摘 要： | 2016年3月—2017年11月对梓桐核心区水域的鱼类资源按季度进行采样调查,对该水域鱼类群落种类组成、生态类型、优势种、多样性指数和ABC曲线进行分析。共采集鱼类43种,隶属4目8科30属,其中,鲤科鱼类种类最多(65.12%);以中上层、杂食性、湖泊定居性鱼类为主;优势种为黄尾鲴(Xenocypris davidi)、银飘鱼(Pseudolaubuca sinensis)和鳙(Aristichthys nobilis);Margalef、 Simpson、 Shannon-Wiener和Pielou指数两年的变化范围分别为3.17～5.01、0.68～0.89、1.79～2.55和0.61～0.84;鱼类群落结构季节变化呈显著差异,且在多数情况下受到中度干扰。研究结果不仅有助于了解千岛湖保护区内的鱼类群落和资源的状况,而且可为兴建水利工程对鱼类群落结构影响提供参考的资料。

| Abstract: | A sampling survey was conducted on the fish resources in Zitong core area from March 2016 to November 2017, and the fish species composition,ecological type,dominant species, community diversity index, community structure, ABC curve were analyzed. A total of 43 species were collected, which belonged to 4 orders, 8 families and 30 genera, and Cyprinidae had the largest number of species, which constituted 65.12% of the total species number. The captured fish were mainly composed of middle uplayers, omnivorous and sedentary species. The dominant species were Xenocypris davidi, Pseudolaubuca sinensis and Aristichthys nobilis. Margalef diversity index, Simpson diversity index, Shannon-Wiener diversity index and Pielou diversity ranged from 3.17 to 5.01, from 0.68 to 0.89, from 1.79 to 2.55, and from 0.61 to 0.84, respectively.The seasonal variation of fish community structure was significantly different, and in most cases it was moderately disturbed. The results of the study will not only help to understand the status of fish communities and resources in the Qiandao Lake conservation area, but also provide reference data for the construction of water conservancy projects to influence the fish community structure. |
