于2000年4月~12月对滇池区域的土著鱼类进行调查发现,滇池土著鱼类由20世纪60年代的26种减少到目前的11种。这11种滇池土著鱼类中,仅有4种生活于滇池湖体,其余7种均生活于滇池湖周一些溪流的上游或溶洞中。通过对土著鱼类及其栖息地的实地调查并结合文献资料,分析了滇池土著鱼类多样性的历史变化,各种类在空间上的变化方式以及滇池土著鱼类多样性迅速降低的原因,并就保护滇池土著鱼类提出具体的解决方法和途径。

Many factors , such as pollution , species int roduction and reclamation around the Lake , have made the indigenous fishes in Dianchi Lake tend to decline or bcome endangered. The results from a survey conducted in 2000 showed that there are only 11 indigenous fishes remaining , and seven of them disappeared for many years in Dianchi Lake but still live in the upper reach of the rivers that flow into Dianchi Lake. By field survey of the indigenous fishes and their habitats , integrated with literature records , the historical change of the indigenous fishes , the spatial change pattern of their habitat sand the factors cont ributing to the fast decline of endemic fish diversity have been analyzed. Measures and approaches have been proposed here to protect these indigenous fishes.
