【摘要】 对栖息在竹林内的濒危物种扁颅蝠的种群数量及其生活环境因子的关系进行了研究,结果表明:扁颅蝠种群数量在6月份有一个明显的低谷期;种群数量与相对湿度呈负相关,与温度相关性不显著;不同洞穴扁颅蝠的数量,受到竹子的自然死亡、风等外力对竹子的破坏作用、洞穴内小环境的变化等环境因素影响。通过对扁颅蝠进行标记研究显示,扁颅蝠并非固定在某一竹洞内居住,而是在不同的洞穴之间交换栖息,或者是一个扁颅蝠的家族拥有多个栖息的洞穴。更多还原

【Abstract】 The population quantity of bamboo bat (Tylonycteris pachypus) that inhabits in one park of Guangzhou and their ecological factors were observed. The result showed: The population quantity of bamboo bat decreased during June. And it was negative correlated with relative humidity and had no relation with air temperature.The population quantity of bamboo bat in different holes was affected by many other factors, such as natural death of Lingnania chungii McCluer(one kind of bamboo),the damage on bamboo, the change of small circumstance in hole and so on. According to study of banded bamboo bat, it does not always stay in same hole, but exchanges in some different holes instead. Perhaps one Tylonycteris pachypus family has several holes for inhabit.更多还原
