山西五鹿山白皮松群落乔木层的种间关联性分析
An analysis of interspecific association of species in tree layer of Pinus bungeana community in Wulu Mountain of Shanxi
摘要
Abstract
A series of techniques including the analysis of variance,2-test, AC coefficient and Ochiai's coefficient were calculated based upon a 2×2 contingency table to analyze and determine the overall association,the statistical significance, and the coefficient of the each species-pair association of 26 arbor species from 50 quadrats in Pinus bungeana community of Wulu Mountain of Shanxi Province. The result indicated that the overall association of 26 kinds of trees in Wulu Mountain of Shanxi Province showed positive correlation, which showed that the P. bungeana was suitable with its external environment. These species pairs existed in two forms:positive correlation and negative correlation, the emergence of positive and negative association between these species pairs, which showed the inner environment of the community and was caused by the heterogeneity of the environment within the community.关键词
