| 为了解南盘江鱼类资源现状,保护和恢复南盘江鱼类多样性,2008年6月至2010年3月,对云南省境内南盘江鱼类现状进行实地考察,结合中国科学院昆明动物研究所馆藏标本和历年相关记录,分析南盘江鱼类种质资源现状。结果表明,云南境内南盘江及其附属湖泊共有鱼类8目、20科、71属、160种;其中,土著种137种,特有种93种,外来种23种。鲤科鱼类最多,有94种,占鱼类总数的58.8%,其次为条鳅科32种,占总数的20.0%,爬鳅科7种,占总数的4.4%。南盘江鱼类种类众多,但由于人为影响,河流污染比较严重,目前已有24种鱼类被列为濒危种类。分析南盘江近两年的鱼类种质资源现状,发现土著种类的数量大幅下降,这与南盘江河流环境恶化和水电开发力度增大密切相关。 |

| Fish surveys of Nanpanjiang River System of Yunnan were conducted from June 2008 to March 2010. Based on field surveys and history records，there were a total of 160 species belonging to 8 orders，20 families and 71 genera in Nanpanjiang River System of Yunnan，China. Among 160 species，137 were indigenous，93 were endemic，23 were introduced. The species of Cypriniade was dominant，including 94 species，accounting for 58.8% of all species，Nemacheilidae ranked the second including 32 species，accounting for 20.0% and Balitoridae ranked the third，including 7 species，accounting for 4. 4%.There were rich fish species in Nanpanjiang RiverSystem，however, because of the serious pollution，24 indigenous species were proved to be endangered or even extinct. This paper analyzed the current situation of fish resources of Nanpanjiang，and revealed that indigenous fish species was decreasing rapidly，as a result of pollution and dams construction on the river. This paper also provided suggestions on the improvement of fish diversity of the river.
