在野外调查和查阅历史资料的基础上,运用濒危系数、遗传价值系数和物种价值系数对哈巴河15种土著特有鱼类进行优先保护顺序的定量研究。结果表明:达到一级急切保护的有哲罗鱼和细鳞鱼2种,占所研究物种总数的13.3%;达到二级急切保护的有北极茴鱼和阿勒泰杜父鱼2种,占所研究物种总数的13.3%;达到三级急切保护的有贝加尔雅罗鱼、北方花鳅、小体高原鳅、江鳕、河鲈5种,占所研究物种总数的33.3%;尚未达到急切保护的有阿勒泰鱼岁、尖鳍鮈、银鲫、北方须鳅、新疆高原鳅、粘鲈6种,占所研究物种总数的40.0%。该研究结果较为真实地反映了哈巴河地区鱼类的受威胁状态和优先保护顺序。
On the basis of field investigation and historical data access, the quantitative study of the order of priority conservation of 15 indigenous endemic fish species in Habahe River was conducted using the endangerment coefficient, genetic value coefficient and species value coefficient. The results showed that there were two species of philosophorus and two species of carolina that reached the first level of urgent protection, accounting for 13.3% of the total species studied; two species of amphibian and Aristophax reached two levels of ecumenical protection, 13.3% of the total number of species; there are five species of Baikaliluo, northern loach, small plateau loach, codfish, perch, 33.3% of the total species studied to reach the three urgent protection; Altay fish age, tip fin 鮈, silver crucian carp, northern loach, loach Xinjiang Plateau, sticky perch 6, accounting for 40.0% of the total species studied. The results of the study more accurately reflect the threatened status of Habahe fish and the order of priority protection.
