| 摘 要： | 为完善新疆博尔塔拉河流域的渔业生态评估及体系养护,2016年11月在博尔塔拉河流域展开资源调查,于干流设置4个监测断面,对该水域鱼类群落结构进行研究。本调查共采集鱼类1515尾,隶属于3目5科14属,共计15种,均为硬骨鱼类;通过相对重要性指数(IRI指数)获得的博尔塔拉河干流的鱼类优势种共计3种,分别为麦穗鱼(Pseudorasbora parva)、棒花鱼(Abbottina rivularis)和新疆高原鳅(Triplophysastrauchii)。基于Bray-Curtis相似性指数的二维聚类分析结果显示,在60%相似水平上空间聚类,可将博尔塔拉河分为上游及下游2组,物种聚类在50%相似水平上可分为Ⅰ～Ⅳ共计4组。典范对应分析(CCA)表明,影响冬季鱼类群落空间结构的主要环境因子为海拔、温度和溶氧。对照历史资料结果表明,博尔塔拉河流域的土著鱼类种类减少;外来鱼类种类逐年增加;经济鱼种减少;鱼类群落小型化明显。本研究可为该流域生态环境评估、水资源开发利用及渔业资源养护提供基础数据,具有一定的参考价值。
