关于森林分类问题的探讨

<正>本文探讨了森林分类的原则、依据和方法,提出两个分类方案:(1)森林的群落分类法,以森林的群落学特征为依据;分类系统分五级,即森林型、森林群系组、森林群系、森林群丛组及森林群丛。(2)森林的综合分类法,分类系统为两级,即第一级以森林的主要用途为依据;第二级以群落建群种为依据。通过讨论比较,认为综合分类法较为合适。

In this paper, the writers discuss the principle bases and metheds for classifying forests. Two methods for classifying forests are suggested as follows ( 1 )The classifying method according to forest communities. This kind of classification of forests are based on the characteristics of forest communities. A typological system of five categories is proposed which, in sequence, are forest type, group of forest formation, forest formation, group of forest association and forest association. ( 2 )The classifying method according to synthetic factors. This kind of classification of forests are based on both the use and constructive species of forests. A tentative typological system for 64 forest types in Jiangsu Province is suggested. A comparison between these two classifying methods shows that the synthetic method is superior to the other one.
