黄腹角雉的栖息地研究

采用样方法对黄腹角雉栖息地的地理特征、植被组成、乔木层、灌木层以及地被植物的特点等方面进行了研究.以相似性指数分析、多样性分析、重要性分析等方法对冬、春、夏3季栖息地植被的特点作了分析.研究结果表明:黄腹角雉对栖息地坡度及坡向具有明显的选择性;栖息地植被层次结构明显,以壳斗科植物为优势的乔木层对决定栖息地植被的外貌和内部环境起着主导作用;冬、春、夏3季栖息地具有一定程度的相似性,同时又各具特点.

THE STUDY OF HABITAT USED BY CABOT'S TRAGOPAN

The habitat studied is in Wuyanling nature reserve of Zhejiang Province. Sample method is used to study the habitat used by Cabot's tragopan on geographical features, structure of vegetation, characteristic of every vegetation layer. The vegetation characteristics of habitats during winter, spring and summer are analized by similarity index analysis, diversity analysis and importance analysis. The results indicate that Cabot's tragopan has a obvious selection to the direction and slope of the habitat. Trees dominated with species of Fagaceae have an important effect to the appearance and inner circumstance of the vegetation. Habitats of winter, spring and summer have similarities to a certain extent, but every one has its own traits.
