The preferred habitat types of Cabot's tragopan in each season were: evergreen-deciduous forest and the broadleaf strips in spring; the broadleaf strips and shrubs in summer and evergreen-deciduous forest and shrubs in autumn; the habitat selected in winter was the same as that in spring but were more relied on by the birds.

黄腹角雉所偏好的栖息地类型，在春季为常绿阔叶--落叶混交林和人工针叶林中的阔叶林条带；夏季为阔叶林条带和灌草丛；秋季为常绿阔叶--落叶混交林和灌草丛；冬季与春季相同，但对这两种类型栖息地的依赖性比春季更强。

This thesis focus on the introduction and analysis of two advanced software in this field: Onyx Treemaker and Visual Nature Studio. This thesis studied topics about theory, application and programming of forest landscape visualization technique. Also a structure of forest landscape visualization system is issued. And the programming of image transparent, which is one of the key techniques of visualization, is carried out during the study of this thesis.

本论文的研究以引进国外行业内的先进软件为中心，包括理论、应用和开发三个方面，对 Onyx Treemaker 树木造型软件和Visual Nature Studio景观仿真软件的建模方法、绘制技术、使用方法等进行剖析，针对森林景观可视化的需求提出一个可视化系统的功能框架，并对系统中的一个关键技术一图像的透明消隐技术进行了开发。

The former' wave width is medium. It feeds mainly on aquatic small insects of order Diptera and Trichoptera, foraging in 5-20cm above water surface and midium- complicated forest by trawling and aerial feeding. The latter's wave width is shortest, which have disadvantage to discriminate targets from enviroment. It feeds mainly on even smaller insects of order Lepidoptera and Diptera, foraging in wide space or sparse-foliage forest by aerial feeding.

为小型蝙蝠，前者声波带宽中等，主要以水生小型的双翅目、毛翅目为食，在水面5—20cm和中等复杂的林中进行拖网和空中捕食，后者声波带宽最窄，主要以小型的鳞翅目、双翅目昆虫为食，在开阔空间内或稀疏林中进行空中捕食，视觉可能在捕食中具有重要的辅助作用。

The results showed that small-scale gaps were the predominant types of disturbance. The average gap density was 12.5 km^(-1). The distribution pattern of gaps was aggregated on south facing slopes and was approximately homogeneous on north facing slopes. Conifer trees were the primary gap-makers in this forest that was dominated by Abies faxoniana, Tsuga chinensis, Betida utilis, both in abundance and diameter rank. The decay class distribution of gap-makers indicated that the mode of gap formation and gap-maker species changed with age of the forest; the contribution of conifer species to gap formation decreased with time and broadleaf species increased.

结果表明：l本区以小型林隙干扰为主，林隙平均密度为12.5个km^(-1)，林隙的分布格局在阳坡和山脊为集聚分布，阴坡近均匀分布；林隙形成木以针叶树为主，岷江冷杉、铁杉和糙皮桦在形成木的数量和径级组成上均居前列。2林隙形成木的腐烂等级分布揭示出林隙形成木的形成方式和种类组成均随时间变化。
