摘要:

基于微立地对雅鲁藏布江中游朗县巨柏种群立地类型进行划分,为探索微环境对巨柏生长的影响,以雅鲁藏布江中游朗县巨柏种群为研究对象,采用定性的经验总结和定量的数学分析相结合的方法,并参考中国森林立地分类、西藏地貌、西藏自然地理及各立地因子进行主成分分析后划分立地类型,共划分出5个立地类型组:岩石裸露地立地类型组、山麓坡地立地类型组、阶地立地类型组、河滩地(河漫滩)立地类型组和水线岸边立地类型组,以及15个立地类型。将雅鲁藏布江中游朗县巨柏种群立地类型与中国森林立地分类相结合,得到了朗县巨柏种群立地类型,可为进一步探索立地类型对巨柏生长的影响以及对西藏河谷地带立地类型划分的方法提供参考。

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
