摘要
2018年7—8月份,对陕西黑河湿地省级自然保护区的鱼类资源现状进行调查研究。结果显示:保护区有鱼类4目7科19种,其中鲤形目CYRINIFORMES为主体,15种,占总种数的78.9%,鱼类种类、数量、个体重量等与过去相比呈明显下降趋势。保护区鱼类组成相对简单,多样性程度不高,群落结构脆弱,稀有种占保护区物种的26.3%,许多稀有种仅发现1尾,保护区重点保护物种秦岭细鳞鲑Brachymystax lenok仅发现2尾。保护区鱼类物种在黑河和渭河交汇区域分布最丰富,海拔梯度400~500m物种分布最多,物种分布基本与保护区所处位置相对应。
From July to August 2018,the fish resources of Shaanxi Heihe Wetland Nature Reserve were investigated.The results showed that there were 19 species of fish belong to 7 families,4 orders,15 species of these were introduced species is Cyriniformes which accounting for 78.9%of the total species.The total number,species and individual weight of fish decreased significantly compared with previous data.The relatively simple fish composition structure and low fish diversity were found in reserve,as well as,the community is fragile,the rare species account for 26.3%of the total species in reserve,only one fish individual was found in some rare species,and two Brachymystax lenok were found which is important fish species for reserve to protect.There are more fish species and higher biodiversity in the area where located at the junction of Heihe River and the Weihe River,height ranged distribution from 400 meters to 500 meters than other areas in the reserve region,the feature of species distribution in reserve is basically compatible with the location of zoogeographical division.
