太白山巴山冷杉林初步研究

在定性分析巴山冷杉林种类组成及生活型港基础上，根据法瑞（Ｂｒａｕｎ—Ｂｌａｎｑｕｅｔ）学派概念，以林下植物种类组成作为依据，用定量分类方法将巴山冷杉划分为：杜鹃──巴山冷杉林；藓类──巴山冷杉林；草类──巴山冷杉林；茶　子──巴山冷杉林；忍冬──巴山冷杉林５个类型，分别简述了各类型特点，并对巴山冷杉林更新状况及大小结构进行了分析研究，认为巴山冷杉林为稳定的异龄林。

A Primary Study on Farges Fir (Abies fargesii)Forests in the Taibai Mountains

Based on qualitative analysis of the species composition and life form spectrum,and by means of quantitative analysis the Abies fargesii forests could be divided into 5 types according to the theory of Braun-Blanquet School if species composition of plants in the forests was used as an index, which were:Abietum rhododendronosum, Abietum hylocomiosum, Abietum herbosum,Abietumd ribedosum, Abietum lonicerosum.Moreover, characteristics of different types of forests were discussed. After analyzing regeneration situation and structure of the forests, it was thought that the forests belonged to stable uneven-agedforests.
