鹦哥岭自然保护区鹦哥岭树蛙种群分布及数量调查

于2010年7月～2012年1月,采用在不同海拔梯度设置样带和样方的方法,对海南鹦哥岭省级自然保护区内鹦哥岭树蛙(Rhacophorus yinggelingensis)的分布和种群数量进行了调查。调查表明,鹦哥岭树蛙分布范围非常狭窄,栖息的生境类型较为单一,仅分布于海拔1 200 m以上的临时性水潭内,种群数量为(2 972±831)只。由于该物种的数量极其稀少,建议提高鹦哥岭树蛙保护等级以加强保护。

Field Survey on Population Size and Distribution of Rhacophorus yinggelingensis in Yinggeling Nature Reserve

We conducted a field survey on the estimated the population size and distribution of Rhacophorus yinggelingensis by using the quadrate method and line intercept method in Hainan Yinggeling Nature Reserve from Jul. 2010 to Jan. 2012, This species live in a specific environment and inhabit at few temporary ponds in very narrow areas at 1 200 m above sea level, and the population quantity is estimated only 2 972±831. Therefore, we recommend to strengthen the protection for this species by upgrade its protection rank.
