浙江松阳安岱后常绿阔叶林的数量分类研究

The Study of Numerical Classification of Evergreen Broad-leaved Forest at An Dai-huo, Song Yang County, Zhejiang Province

本文运用法瑞学派的方法,对浙江松阳安岱后的常绿阔叶林进行了调查,共收集样地资料29个。利用二歧指示种分析法(TWINPAN程序)对乔、灌、草三层分别进行运算,得到三层的初步结果,然后把三层第一次分划的结果进行统一分析,最后确定了三个群丛。作者认为使用法瑞学派的方法。结合TWINSPAN数量分类程序对某一地区亚热带常绿阔叶林进行数量分类是一种快速可行的方法。

This study using Braun--Blanquet method investigated the evergreen broad--leaved forcst of An Dai--huo, Song Yang county, Zhejiang province and obtained 2 9 samples, Using TWINSPAN program we computed the tree layer, shrub layer and herb layer data and got three preliminary results. Then we divided the 2 9 samples to three association on the basis of the first divjsion results of the three layers. The authors think that combining Braun-Blanquet method with TWINSPAN program is fast and practical for numerical classification of evergreen broad- leaved forest in some subtropic arcas.
