摘要/Abstract

摘要： 根据37块标准地的调查资料,系统研究了太白红杉林的群落学特征,并通过K-means聚类分析对群落进行了分类。秦岭太白红杉林可划分为3个林型组,即灌木太白红杉林、草类太白红杉林、藓类太白红杉林,和16个林分类型。应用NMDS排序技术,分析了太白红杉林下草本植物生态种组的特点,探讨了各林分类型与环境因子的关系,从而为保护经营这一珍稀植物群落提供了科学依据。

Abstract: Based on data obtained from 37 sampled plots, the phytoxoenological features of the forests of Larix chinensis in Qinling Range were systematically analysed. The natural forests were classidied into 3 forest-type groups,i. e. Lariceta fruticosa, Lariceta herbosa, Lariceta bryophyteta, and 16 stand types by means of K-means clustering. The ground-flora was analysed with NMDS ordination to understand the relationship between the stand types and environmental factors, which procided a scientific basis for conservation of this rare phytocommunity.

Key words: Larix chinensis, K-means clustering, Phytocoenological feature, Stand type, NMDS ordination
