| 摘 要： | 为研究大熊猫对不同森林生境的利用情况,2012年和2013年在四川省王朗国家级自然保护区布设了30条调查线路开展了大熊猫生境调查,对49个大熊猫原始林利用样方和43个次生林利用样方中的16个变量进行了调查和统计分析。研究发现大熊猫可以利用采伐后自然恢复50多年的次生林,但原始林生境和次生林生境仍存在较大差异：与大熊猫所利用的原始林生境相比较,次生林生境的乔木胸径较小,灌木密度和灌木胸径较大,倒木较少。研究发现,加强对次生林的保护对大熊猫生境的保护工作有重要的意义。

| Abstract: | The habitat use of giant panda in Wanglang Nature Reserve was studied in 2012 and 2013 to investigate the habitat requirement and preference in primary and secondary forests. Sixteen ecological factors were chosen to be surveyed in 49 plots of primary forest and 43 plots of secondary forest. The results showed that the secondary forest has been used by giant panda,while the habitat of giant panda in primary and secondary forests differed significantly. Compared to the primary forest used by giant panda,the secondary forest had less fallen logs,the trees had smaller DBH,the shrubs had higher density and larger DBH. Predicted by the results,the suitable habitat for giant panda can be enlarged by protecting the secondary forest. |
