中文摘要：

对不同山系大熊猫生境选择横向比较迄今未有报道．笔者等以大熊猫在生境利用过程中留下的粪便等为依据，通过设置大小不同的3种样方，对岷山山系唐家河自然保护区和邛崃山系蜂桶寨自然保护区大熊猫的生境选择进行了初步比较．在研究的13个生境变量中，两地大熊猫在竹子密度、竹子高度、竹子基茎、灌木密度和灌木距离等5个生境变量的选择上存在极显著差异，而对其它生境变量的选择差异不明显．两地大熊猫对生境平均利用时间的长短与生境质量高低相一致．大熊猫在唐家河与蜂桶寨两地生境选择上的异同反映了不同区域大熊猫对生境的选择既有物种的相似性，又有适应局部环境差异的可塑性．分析认为两地竹子、灌木种类的不同及唐家河自然保护区1991年发生的特大洪水可能是导致这种差异的外在原因．

英文摘要：

Giant panda＇s habitat choice of different mountains has not been reported. Thus, we set sizes of three different kinds of squares in Tangjiahe Nature Reserve located in the Min Mountains, and in Fengtongzhan Nature Reserve located in the Qionglai Mountains, respectively. We identified habitats selected and utilized by giant pandas through droppings left. Among thirteen habitat variables, five of them, namely bamboo height, density and basal diameter, shrub density and distance differed significantly between in Tangjiahe and in Fengtongzhai Nature Reserves, and for the others, the differences were not significant. The giant panda＇s habitat selections in the two places reflected the similarity of the giant pandas in different regions, but＇also their plastic adaption to local environmental differences. For the giant panda, two reasons perhaps resulted in the difference in habitat selection between the two reserves. One was that different species of bamboos and shrubs existed in these two reserves; the other was the flood occurred in 1991 in Tangjiahe Nature Reserve, which resulted in the development difference of communities between in Tangjiahe and in Fengtongzhai Nature Reserve. Average dropping groups left in habitat in general indicated average utilization of habitats by giant pandas.
