摘要:
根据2×2联列表,运用方差分析、χ2检验、AC指数、Ochiai指数等技术,对山西五鹿山白皮松群落50个样方内的26种乔木的种间总体联结关系以及各种对间关联显著性和关联系数进行分析与测定。结果表明:该地区26种乔木的总体联结关系以正关联为主,表明白皮松林与其外环境是相适应的;种对间以正、负关联两种形式存在,成对物种之间正负关联的出现,是该群落内环境的表现,也是由群落内环境异质性所致。
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.
