甘肃省大熊猫生境分析

根据2000～2001年甘肃省第3次大熊猫调查资料,利用SPSS和SAS软件,对甘肃省大熊猫Ailuropoda melanoleuca的生境进行了统计分析.结果表明:甘肃省大熊猫主要栖息在以缺苞箭竹Fargesia.denudata为优势的下木种群森林群落中,其垂直活动范围主要在海拔1 600～2 800 m间,水平分布在文县和迭部一带;竹类种群的特性、地理环境和森林群落的完整性是大熊猫栖息生存的三个主要综合要素;甘肃省大熊猫的生境特征基本上稳定,但该区竹类种群的正态性分布和人为干扰强度是构成其生境不稳定的潜在因素.

Analysis of Giant Panda Habitat in Gansu Province

According to the third survey on giant panda in Gansu from 2000 to 2001 and utilizing the software of SPSS and SAS, authors of this paper conducted a statistic analysis of the giant panda habitat. The result shows that the giant panda habitat in Gansu is an under-plant population of forest communities with F.denudate as the dominant species; that giant pandas make movements at the altitudes ranging from 1 600 m to 2 800 m in Wenxian county and Diebu county; that the characteristics of bamboo population, geographical environment, along with the integrity of forest communities, are taken as the three dominant factors in influencing the life of panda; and that the features of the habitat are basically stable but reasonable distribution together with strong artificial disturbance is considered as the potential factor resulting in the habitat unstable.
