四川王朗国家级自然保护区大熊猫与家畜竞争关系

Competition Relationship Between Giant Panda and Livestock in Wanglang National Nature Reserve,Sichuan

基于四川王朗国家级自然保护区2009年的野生动物生境监测数据,利用列联表法、生态位重叠法和分布频率法,研究了大熊猫与家畜的竞争关系。结果表明:四川王朗国家级自然保护区的大熊猫与家畜竞争的主要环境条件是,海拔(A)为2 500 m≤A<3 000 m的针阔混交林中,乔木特征是高度(D)为20 m≤D<30 m、郁闭度(E)为0.25≤E<0.50、乔木胸径(F)为20 cm≤F<30 cm;灌木特征是高度(G)为2 m≤G<3 m、盖度(H)为25%≤H<50%;竹子特征是高度(I)为2 m≤I<3 m,缺苞箭竹(Fargesia denudate)生长状况良好。此研究可以为大熊猫生境恢复、保护和管理提供科学依据。

Frequency distribution method, erosstab method and niche overlap method were used to assess the competition relationship between giant panda and livestock based on the inventory data in 2009 in Wanglang National Nature Reserve, Pingwu County of Siehuan Province. The competitive environment conditions between giant panda and livestock in Wanglang National Nature Reserve were obtained as the elevation 2 500-3 O00 m, the mixed conifer and broad-leaved forest, the mean height of trees 20-30 m, the crown density 0.25-0.50, the mean diameter at breast height 20-30 cm, mean height of shrubs 2-3 m, and shrub coverage 25%-50%. As for the bamboo, Fargesia denudate which grew well was the favorite habitat for both giant panda and livestock, with the mean height of 2-3 m.
