| 中文摘要: |
| 龙羊峡上游是黄河重要的鱼类资源分布区，是目前黄河上游仅有的几个鱼类生态保护相对完好的区域，基本未受到人为活动的影响。基于2009－2013年连续多次调查，研究了黄河龙羊峡上游鱼类资源现状及群落多样性特征。结果表明，黄河龙羊峡上游调查到土著鱼类10种，隶属于1目、2科、7属，全部为中层和底栖鱼类，其中洄游性鱼类5种、定居性鱼类5种。各采样点渔获物组成存在一定差异，渔获产量和规格以扎陵湖较高，多样性以羊曲和班多较高；并提出了相应的保护对策。 |
| 英文摘要: |
| The upstream of Longyang Valley is a very important area of fish resources of the Yellow River，which is one of the few relatively intact fish ecological protection areas in the upper reaches of the Yellow River for not affected by human activities. From 2009 to 2013, the constant surveys were made on the situation of fish resources and community diversity characteristics of this area. The Results showed that total of 10 species of native fishes were collected, falling into 1 order, 2 families and 7 genera , which all belonged to the middle and bottom-dwelling fish ; among which 5 species were migratory fish, 5 species were sedentary fish; the composition of catches presented some difference for each sampling point ; in Zhaling Lake the fish production and fish size were much higher and larger, while the fish biodiversity of Banduo and Yangqu was much higher. The protection measures were also provided based on the situations of fish resources. |
