摘　　要：为探索森林群落乔木层与林下大熊猫取食竹的相关关系,利用样线法和样方法,对大相岭大熊猫栖息地森林群落乔木层结构特征与林下冷箭竹(Bashania faberi)生长指标进行调查,构建线性混合模型(LMM)和广义线性混合模型(GLMM)进行分析。结果表明:(1)乔木郁闭度对冷箭竹平均高度影响显著,乔木株数对冷箭竹株数影响显著,乔木平均高度和平均胸径对冷箭竹发笋量、平均基径和平均高度影响显著。(2)冷箭竹发笋量、平均高度和平均基径均随乔木平均高度和乔木平均胸径增加而增加;冷箭竹株数随乔木株数增加而减少;冷箭竹平均高度随乔木层郁闭度增加而减少。本研究以期为该区域大熊猫栖息地的恢复提供量化依据。This paper aims at exploring the correlation between the tree layer and understory feeding bamboo of forest community.Line transects and quadrats are employed to investigate the structural characteristics of tree layer and growth index of understory Bashania faberi of forest community in the giant panda habitat of Daxiangling mountain.The Liear Mixed Model(LMM) and generalized linear mixed model(GLMM) are constructed for making analysis.The results show as follows:(1) the canopy density of trees layer have significant effects on the average height of bamboo;the number of bamboo shoots is obviously affected by the number of trees while the number of bamboo shoots, average basal diameter and average height of bamboo are significantly affected by the average height and diameter at breast height of trees;(2) as the average height and the average DBH of trees increase, the number of bamboo shoots, average height and the average basal diameter will rise;when the number of trees increase, the number of bamboo plants will be reduced and the average height of bamboo plants will decrease with the increase of canopy density of tree layer.This study has provided a quantitative basis for the restoration of the giant panda habitat in this region.
