A taxonomic study on the bamboo as the main food of giant panda from Mt.Qinling(II)

目的为理清秦岭地区大熊猫最集中分布的陕西佛坪国家级自然保护区及陕西周至县老县城自然保护区大熊猫主食竹的种类和分布区域。方法采用常规的植物分类学研究方法,通过大量的野外调查、室内标本鉴定、查阅有关标本室的标本及文献资料考证,对所采集的标本进行分类学研究。结果这两个保护区内共有野生禾本科竹亚科植物3属、5种,其中巴山木竹Bashaniafargesii和秦岭箭竹Fargesia q inlingensis为该区域内分布面积最大的竹种。结论在这两个保护区内,巴山木竹和秦岭箭竹是大熊猫最主要的主食竹种,龙头竹Fargesia dracocephala和华西箭竹Fargesia nitida次之。为进一步研究大熊猫主食竹种提供了基本的资料依据。
