瑶山鳄蜥洞穴的生态学初步研究

通过对广西昭平鳄蜥的洞穴采用封堵法和坐标法进行研究表明,植被盖度和洞穴之间呈现明显的正相关性.调查中共测量洞穴124个,其深度在18～132cm之间.在鳄蜥活动时间的分配上,洞穴占据了近1/3,故洞穴是其生命活动的一个重要条件.鳄蜥喜欢选择深邃弯曲的石缝、石洞或树洞居住或越冬,洞穴内湿度较大但不被水浸泡,隐蔽程度高、避光,洞口常有较密的植被.

Ecology of Chinese Crocodilian Lizard in Burrow

The research is about the ecology of crocodilian lizard in Zhaoping, Guangxi through plugging and coordinate methods The results indicated that vegetation coverage and burrow had conspicuous positive correlation. 124 burrows were measured in the investigation. The depth of the burrows ranged from 18cm to 132cm. On the distribution of the activity time, the time in burrow took up about one third, so burrows were the important condition in the life. Generally, crocodilian lizard selected serpentine and deep swallet, rock shelter or hollow tree to live and wintering. The burrows had large humidity but they were not soaked by water. The burrows were well evaded and the light could not directly touch it . There were often thick vegetation around cave openings.
