我国特有种滇螈的绝灭及其原因分析

滇螈是中国特有的两栖类，是云南省二级保护珍稀动物，生活于云南高原淡水湖泊滇池。已于20世纪70年代末绝迹。绝迹原因主要是“围湖造田”，湖水严重污染，大搞建筑设施，水生生物严重减少以及外来引种，使它们的栖息环境、食物、繁殖都受到严重影响，导致最后绝种。它的绝种却为我国珍稀野生动物，特别是两栖爬行动物的保护，提供十分有益的经验教训。

CYNOPS WOLTERSTORFFI, AN ANALYSIS OF THE FACTORS CAUSED ITS EXTINCTION

The Yunnan salamander, Cynops wolterstorffi (Boulenger, 1905), is endemic to China and had been found only in Kunming Lake, a freshwater lake in Yunnan Plateau. It extincted in the wild in the end of the 1970s. The factors caused its extinction were mainly due to "reclaim land from the lake" in 1970, seriously water pollution, constrion of buildings, reduction of aquatic plants, and introduction of foreign species. The reasons mentioned above deeply affected habitat, food,and reproduction of Yunnan salamander. The extinction of Yunnan salaneder provides a good experience and lesson in protection of wildlife,especially amphibians and reptiles.
