摘要
In this paper,the quantitative approach is applied on the study of coniferous forestbased on the data which were collected by the field investigation in Daxinganling region.The mainpurpose is objectively to show the position of communities in the space and the relationship be-tween the community and environment.By means of ordination,it is found that dahurian larch for-est,mongolian scots pine forest and korean fir forest lie in different positions. Gradient analysis ofthree dominant types of conigerous forest has revealed the difference of ecological amplitude,thedifference is one of the important reasons that determine the different communities in the differentenvironment.
In this paper, the quantitative approach is applied on the study of coniferous forest based on the data which were collected by the field investigation in Daxinganling region. The main purpose is objectively to show the position of communities in the space and the relationship between the community and environment. By means of ordination, it is found that dahurian larch forest, mongolian scots pine forest and korean fir forest lie in different positions. Gradient analysis of three dominant types of coniferous forest has revealed the difference of ecological amplitude, the difference is one of the important reasons that determine the different communities in the different environment.
