摘要
动物空间分布格局在昆虫中研究较多 ,而在大型脊椎动物中研究却较少 ,这主要是受研究方法的限制。为此 ,作者对此方法进行了改进 ,提出了一种新的研究方法 ,临时空间样方法 ,并将其应用到冶勒自然保护区大熊猫的调查研究中去。结果表明 :( 1 )大熊猫粪团在野外的分布属于聚集分布 ,并与负二项分布拟合较好 ;( 2 )在冶勒自然保护区 ,生活有 8只左右的大熊猫 ,其密度为 0 0 32 5只 km2 ,如只考虑竹林内的生态密度 ,也只能达到 0 3395～ 0 5340只 km2 。
Because of the limitation of the spatial plots method, the study of the spatial distributional pattern of wildlife focused on hexapods, there was very few research on large vertebrate with the method In order to overcome those limitation, on the base of the old one, a new method——temporary spatial plots method, was developed and used on the study of giant panda in Yele Natural Reserve The result showed: (1) The distribution of giant panda's feces is a aggregative distribution and belongs to begative-binomial distribution (2) In Yele Natural Reserve,8 individuals of giant panda were estimated surviving, with the density 0 032 5 ind/km 2 In the bamboo forests, the ecological density was 0 339 5-0 534 0 ind/km 2, The future of the giant panda in Yele Natural Reserve is pessimistic
