| 摘 要： | 根据2012年6月-2013年10月对汀江大刺鳅国家级水产种质资源保护区4个采样江段的鱼类资源季节调查数据,分析了该保护区的鱼类群落结构及影响因子。调查共采集鱼类38种,隶属4目、12科30属;其中福建省保护动物大刺鳅(Mastacembelus armatus)1种,福建省特有种拟腹吸鳅(Pseudogastromyzon fasciatus)、圆斑拟腹吸鳅(Pseudogastromyzon cheni)、斑纹缨口鳅(Crossostoma stigmata)3种。采用Pinkas的IRI指数进行分析,保护区鱼类优势种有宽鳍鱲(Zacco platypus)、黄颡鱼(Pelteobagrus fulvidraco)、鲇(Parasilurus asotus)、侧条厚唇鱼(Acrossoch eilus parallens)、泥鳅(Misgurnus anguillicaudatus)和大刺鳅等6种;鱼类生态类型以杂食性、底栖和山溪定居性为主。保护区上游鱼类多样性指数和物种丰富度指数高于下游。用pearson相关分析法,鱼类多样性指数与浮游动物多样性指数、河道变化、人类活动影响相关性显著。典范对应分析发现3个环境指标主要影响平鳍鳅科鱼类。

| Abstract: | According to the fisheries resource data collected from June 2012 to October 2013, the status of fish community structure and environmental indicators in 4 sampling stations in national fisheries resources protection zone in Tingjiang River were analyzed. The results showed that the captured 38 fish species belong to 4 orders, 12 families and 30 genera. Mastacembelus armatus is protected fish of Fujian Province and Pseudogastromyzon fasciatus, Pseudogastromyzon cheni, Crossostoma stigmata are endemic species in Fujian Province. Fish community through IRI indexes were analyzed, Zacco platypus, Pelteobagrus fulvidraco, Parasilurus asotus, Acrossoch eilus parallens, Misgurnus anguillicaudatus, Mastacembelus aculedtus were the dominant species .The ecological types of the fish consisted of benthic type, omnivorous type and adapting to stream settled. Three diversity indexes which are Shannon-Wiener diversity index(H), Margalef diversity index(D), Evenness index(E) are used to analyze the characteristics of species diversity. Shannon-Wiener diversity and Margalef diversity index in the upper river were higher than those in the lower river. Pearson correspondence analysis showed that the Shannon-Wiener diversity index of zooplankton, channel-change and human activity had the significant correlation with fish diversity index . Canonical correspondence analysis found that three main environmental indicators mainly influence Pseudogastromyzon fasciatus, Pseudogastromyzon cheni and Crossostoma tinkhami. |
