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.
