The Giant panda is an ancient animal. Its food habit is nearly monophagous that tends to lead it to be endangered. For increasing its population, it is necessary to stu-dy its food base and habitat environment. Based on food researches of Giant panda , this article discussed sysmatically the living environment and utilization of different types of food base in Qinling mountain. The results show:

本文从研究大熊猫食物基地的角度出发,比较系统地讨论了秦岭大熊猫分布区的自然环境和竹林的基本概况。研究结果表明:1、秦岭大熊猫分布区的竹种资源丰富,有6属14种,竹林面积约8.43万公顷。2、构成大熊猫食物基地的竹种有3属3种,面积约占该区竹林总面积的99.7%。3、根据竹林类型、环境及大熊猫的利用状况,秦岭大熊猫的食物基地可以划分为3个小区。4、在正常情况下秦岭大熊猫食物基地至少可供7倍于今数量的大熊猫生存。

Giant pandas in middle and second high hill′s theropencedrymion or aciculisilvae take food from bamboo and get shelter from forests. Bamboos are remarkaly capable of vegetative propagation and restrain the growth of tree seedlings with a bamboo′s cover ratio of over 50%.But with the dieback of bamboo after the periodic flowering, it takes over ten years from the seed germination to seedling growth into dense forest.

Giant pandas in middle and second high hill′s theropencedrymion or aciculisilvae take food from bamboo and get shelter from forests. Bamboos are remarkaly capable of vegetative propagation and restrain the growth of tree seedlings with a bamboo′s cover ratio of over 50%.But with the dieback of bamboo after the periodic flowering, it takes over ten years from the seed germination to seedling growth into dense forest. This period is the most favourable time for the restoration of the giant panda′s habitat through reforestation. So in giant panda′s distributive areas it is highly advisable to plant forests of mixed trees and bamboos on clear -cut slashes, and to plant the same kind of trees that once were in the area but now cut to restore the forest community structure, raise the survival rate of bamboo seedlings, and creatd a favourable environment for the growth of the giant panda. All mentioned above is an imortant maasure to protect giant pandas.

分布于中山和亚高山针阔叶混交林和针叶林下的大熊猫以竹为食,以森林为隐蔽。竹子无性繁殖力强,若是竹盖度达50%以上,就会抑制乔木层树种幼苗的生长发育。但竹子周期性开花枯死后,从种子萌发到幼苗生长成林需要10年以上的时间,这是恢复大熊猫生境的林木更新的最佳时期。因此可在大熊猫分布区被皆伐后的迹地上营造竹树混交林;在择伐后的林区种植被择伐后的树种,恢复森林的群落结构,提高竹子幼苗的成活率,创造适宜大熊猫生存发展的生态环境,是保护大熊猫的重要措施。

According,to the natural differential law of the giant panda distribution areas and the theories of systematic ecology and eec-economics,an analysis is given to the main factors which affects the ealstence and habitat of aunt pandas,and the differential law of giant panda distribution area and the division principles are also explained.

本研究以大熊猫分布区域的自然分异规律为基础,应用发生学观点,结合系统生态学和生态经济学理论,对大熊猫分布区的自然地理和社会经济条件,以及影响大熊猫生存和栖息地的主要因素进行了综合分析论证,阐明大熊猫分布区的地域分并规律及分区的原则依据,并拟定分类系统、单位,初步将大熊猫分区的立地类型分为5个立地区,9个立地亚区,27个立地小区。并对各立地区的立地特征进行了阐述,提出了自然保护管理、林业经营的发展方向和宏观战略措施.同时,指出了大熊猫分布区立地的低级分类尚待深入调查研究和完善。
