摘要: 在2002年9月,分别利用洞穴深度法、标志重捕法和洞口计数法对分布在若尔盖草原荒漠中的青海沙蜥(Phrynocephalus vlangalii)的种群密度进行调查,所得的结果分别是190.4、76.8和250.7只·1000 m-2。通过对3种结果的比较与分析,证明洞穴深度法有较高的可靠性,这种方法的理论依据是:沙蜥(Phrynocep halus)是一种变温动物,不能长时间处在温度低于致死低温(-2.5℃)以下的环境中,为了能够成功地度过漫长而寒冷的冬季,它必须居住在深度达到最大冻土层之下的洞穴中。这是沙蜥躲避低温伤害的一种行为机制。该方法可以适用于分布在中国的沙蜥属的其它物种密度调查。

Abstract: By the methods of burrow depth,mark-recapture and burrow account,this paper investigated the Phrynocephalus vlangalii population density on zoige desert in September 2002.The results showed that the population density obtained by these methods was 190.4,76.8 and 250.7 ind·1 000 m-2,respectively.Burrow depth method was proved to be highly reliable after comparing and analyzing the results,because Phrynocephalus is a kind of cold-blood animal not able to live in the environment where temperature is below the lethal temperature(-2.5℃) for a long time but inhabit in the burrows deeper than the maximum depth of frozen earth to live through the long cold winter,which is a behavior mechanism of P.vlangalii to protect itself from low temperature.It's suggested that burrow depth method could be applicable to other species of Phryhnocephalus distributed in China.
