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范四川大學(xué)碩士學(xué)位論文圍內(nèi); 2 )主要利用植被類型中的針闊混交林,選擇有缺苞箭竹、而且缺苞箭竹生長良好的生境,對位置和森林起源這兩個生境因素的不同水平,都是隨機利用,沒有表現(xiàn)出明顯的偏好; 3 )大熊貓明顯回避那些人類干擾強度大的生境( xz二22 . 000 , df = 3 , p = 0 . 000 ) ;伐木和放牧對大熊貓食竹的生長狀態(tài)有明顯影響,對發(fā)生采藥和偷獵的生境沒有明顯回避;對于人類干擾強度大的生境,大熊貓利用頻度很低,干擾弱或中等時,表現(xiàn)出隨機利用;對于沒有干擾的生境,是高頻利用。
