摘要
为了寻找适合大鲵生活的各类水体环境因子以利于大鲵的保护和人工养殖,对湖南省壶瓶山自然保护区进行了实地考察,并对保护区内9条溪流中的11个断面和室内大鲵饲养池进行了水质分析.分析结果表明,保护区内野生大鲵适宜于生存在清澈透明、水流速度缓慢、水温为9～25℃、pH值为中性或弱碱性、溶解氧含量高、硬度大、COD低于15 mg/L、TP低于0.02 mg/L的清洁水体中.
In order to enhance the protecting and artificial breeding of the Chinese giant salamanders and find favorable water living environment factors,investigations were carried on the natural reserve of Hupingshan in Hunan Province for analyzing water quality of eleven sections of the nine rivulets and indoor Chinese giant salamanders breeding ponds.The results show that most suitable living environment of the wild Chinese giant salamanders in the natural reserve is transparent,slow clean water flowing with characteristics of temperature belong 9～25 degrees,weak alkaline or neutral pH value,high dissolved oxygen content,higher hardness,COD less than 15 mg/L and TP less than 0.02 mg/L.
