Abstract:

In order to explore the impact of micro environment on the growth of Cupressus gigantean,this paper takes the Cupressus gigantean population of Nang County in the middle reaches of the Yarlung Zangbo as the research object,a method combining qualitative experience summary and quantitative mathematical analysis was used. Based on the principal component analysis of "Forest site classification in China","Land forms of Tibet","Natural geography of Tibet" and each site factor,the following five site types are classified:site type group of exposed rock,site type group of piedmont slope,terrace site type group,river beach(flood plain)site type group,waterfront site type group and 15 site types. Combining the site types of Cupressus gigantean population in Nang County in the middle reaches of Yarlung Zangbo River with the classification of China's forest sites,the site types of Cupressus gigantean population in Nang County were obtained. It can provide a reference for further exploring the influence of site types on the growth of Cupressus gigantean and for the method of site type division in Tibet River Valley.

Key words: forest site, site classification, Cupressus gigantean, Yarlung Zangbo River
