摘　　要：对云南海峰自然保护区鱼类区系调查,结果共获鱼类11种,隶属4目6科11属。其中引入种9种,土著种仅2种,无特有种类。海峰湿地间歇性干涸明显,是一较为封闭的高原水域生态系统。以湿地鱼类区系组成为线索,认为在湿地内无土著种,更未形成狭域分布的特有种。此事实强烈地暗示,海峰湿地的形成历史可能极近,只在数万年之内。海峰湿地属于内陆湿地中的时令湖生态系统,还兼有人工湿地中蓄水区湿地类型的特点。The ichthyofauna of Haifeng Nature Reserve was investigated. The results showed that there were 11 species of freshwater fishes subjected to 11 genera, 6 families and 4 orders, which included 9 invasive species, 2 aboriginal species and without endemic species among them. Water dried up seasonally in Haifeng wetland, whose ecosystem was an insular plateau lake. With the clew of iehthyofauna composition, it was considered that there was no aboriginal species as well as endemic species evolved in this insular system. The facts strongly implied that the forming history of Haifeng wetland was possibly very short and not beyond a few ten thousands years. Haifeng wetland was a seasonal inland wetland with the character of an artificial reservoir.
