长白山北坡暗针叶林群落特征
Community characteristics of dark coniferous forest on north slope of Changbai Mountain
摘要
Abstract
The dark coniferous forest was distributed between 1100m and 1850m in the subalpine of Changbai Mountain,and the distribution pattern of species composition along elevation gradient in dark coniferous forest on north slope was sampled and analyzed in this research.The α and β diversity were used to measure the community diversity of the forests,and community coefficient,which was one kind of β diversity in essence,was used to analyze the similarity of species composition between the communities or plots.Based on these analyses,communities were classified according to Euclidean distance by Ward's method.The results showed that the dominant tree species Picea jezoensis and Abies nephrolepis were distributed nearly over the whole transect,and the companion trees and most of shrubs were found in certain fragments respectively.The total number of species of the plot varied slightly,but species composition among the plots varied greatly along with the elevation variation.This trend reflected the high habitat diversity of this forest zone.The dark coniferous forest could be divided into 2 or 3 types by the classification analysis,and this result was similar to that coming from calculating community coefficient between plots in the same side with different elevations.关键词
