| 摘 要： | 本文应用DCA排序分析研究阔叶红松林的分布和林型分异与环境梯度变化的相关性，指出随海拔高度的升高而引起的诸如水分、温度等因子的综合变化，是影响阔叶红松林群落多样性的主要的复合环境梯度，其次是局部地型或微地型条件的变化。在群落分类过程中，应用了次级排序技术，并给出一个阔叶红松林的分类系统。

| Abstract: | Detrended Correspondence Analysis is used to analyse the distribution of Korean Pine-broadleaved forest along the environmental gradients and the relation between varities of forest types and environmental changes. The results show that the integrated changes of various factors, such as water temperature and humidity in response to increasing altitudes in Changbai mountain, are the main gradient which decides the diversity of Korean Pine-broadleaved forest, the next is the changes of local topography and micro-topography. The technique of secondary ordination is applied to classify the Korean Pine-broadleaved forest and a classification system is given at the end of the paper. |
