摘要
利用样点法对裕河园区鱼类物种多样性和区系进行调查,并对受威胁因素进行分析。结果表明:大团鱼河优势种为宽鳍鱲(Zacco platypus),裕河为多鳞白甲鱼(Onychostoma macrolepis)和红尾荷马条鳅(Homatula variegata),让水河为尖头鱥(Rhynchocypris oxycephalus),白马河和岷堡沟分别为短体荷马条鳅(Homatula potanini)和粗壮高原鳅(Triplophysa robusta)。裕河园区分布有国家二级重点保护鱼类5种,长江特有鱼类20种,外来种1种。钝吻棒花鱼(Abbottina obtusirostris)、半■(Hemiculterella sauvagei)、银鮈(Squalidus argentatus)、黑鳍鳈(Sarcocheilichthys nigripinnis)和斑鳜(Siniperca scherzeri)为5种甘肃省新记录。鱼类区系属华西区且与华东区和华南区相邻。受威胁因素包括水利设施、水质污染、河床挖沙等。本研究为裕河园区鱼类资源多样性提供基础型数据。
Species diversity and fish fauna in Yuhe Park were investigated with point sampling method,and threatened factors were also analyzed.The results showed that the dominant species in Datuanyu river was Zacco platypus,Onychostoma macrolepis and Homatula variegata in Yuhe river,Rhynchocypris oxycephalus in Rangshui river,Homatula potanini and Triplophysa robusta in Baima and Minbaogou rivers,respectively.There were 5 species of national second-level protected wild animals,20 species of Yangtze river endemic fish,and 1 species of invasive fish in Yuhe Park.Abbottina obtusirostris,Hemiculterella sauvagei,Squalidus argentatus,Sarcocheilichthys nigripinnis,and Siniperca scherzeri were five new records in Gansu province.The fish fauna belonged to West China and was adjacent to East China and South China.Threatened factors included water conservancy facilities,water pollution and dredging.This study provides fundamental data for the diversity of fish resources in Yuhe Park.
