The results show that the soil animal number and diversity are the highest in tsuga stand , followed by yusania and miscanthus stands 林相中土壤动物数量及类群数以铁杉林为最多，其次为箭竹林及高山芒。

Giant pandas live in broadleaf and coniferous forests with a dense understory of bamboo , at elevations between 5 , 000 and 10 , 000 feet 大熊猫生活在长有茂密箭竹的阔叶与针叶混交林里，海拔在5 , 000和10 , 000英尺之间。

Collembola is dominant in tsuga stand , enchytraeidae is dominant in yusania stand , but there was no particularly dominant tax on in miscanthus type 优势类群上铁杉林为跳虫类、玉山箭竹林为线蚓类，高山芒则无明显之优势类群。

Most of the pandas are distributed between 2 600 - 2 800 m ; 2 ) the pandas more often exploit the conifer - and - broadleaf - mixed forests and prefer to feed fargesia denudafa and more of their activities happen in forests where arrow bamboo grows better ; 3 ) the pandas avoid habitats where human disturbance is intensive ( x2 = 22 . 000 , df - 3 , p = 0 . 000 ) ; logging and livestock grazing significantly influence feeding habitats of pandas , while herb collecting and poaching has not . the giant pandas prefer the habitats where no human disturbance occurs . in conclusion , human activitires have intensively influenced feeding and other activities of the giant panda and its habitats 垂直主要分布在海拔2600 - 2800m范四川大学硕士学位论文围内; 2 )主要利用植被类型中的针阔混交林，选择有缺苞箭竹、而且缺苞箭竹生长良好的生境，对位置和森林起源这两个生境因素的不同水平，都是随机利用，没有表现出明显的偏好; 3 )大熊猫明显回避那些人类干扰强度大的生境( xz二22 . 000 ， df = 3 ， p = 0 . 000 ) ;伐木和放牧对大熊猫食竹的生长状态有明显影响，对发生采药和偷猎的生境没有明显回避;对于人类干扰强度大的生境，大熊猫利用频度很低，干扰弱或中等时，表现出随机利用;对于没有干扰的生境，是高频利用。

It was found that : ( 1 ) the vegetation type of xiaozhaizigou nature reservation are broad leaved forest and coniferous deciduous forest , subalpine coniferous forests ; ( 2 ) there are " fargesia rufa , f . denudata , f . nitida , bashania fangiana " in various vegetation type in xiaozhaizigou nature reserve , especially mixed coniferous and broad - leaved forests and subalpine coniferous forests ; ( 3 ) in xiaozhaizigou , the broad - leaved forest , mixed coniferous and broad - leaved forests , and subalpine coniferous forests were suitable habitat for pandas ; ( 4 ) with the ascension of altitude , the vegetation type alters naturally and takes on natural state 结果表明： ( 1 )小寨子沟大熊猫生境的植被类型有2种：阔叶林和针叶林； ( 2 )小寨子沟自然保护区内分布有青川箭竹、缺苞箭竹、华西箭竹、冷箭竹等多种箭竹，这些作为大熊猫食料的箭竹广布在各种植被类型中，尤其是针阔混交林和亚高山针叶林； ( 3 )大熊猫对生境的群落结构有较广的适宜性，阔叶林、针阔混交林、亚高山针叶林均可作为它的适宜生境； ( 4 )小寨子沟自然保护区内的植被类型是随海拔的升高而自然过渡的，呈现出受人类活动影响较小的自然状态。
