云丘山地区灌木群落优势种数量关系
Interspecific relationship of dominant shrub species in Yunqiu Mountain area
摘要
Abstract
With important value matrix and 2×2 list of 69 shrub samples as the foundation,with variance ratio meth-od,x2-test,Pearson correlation coefficient and Spearman rank correlation coefficient and real station,the relevance of 20 dominant species and 190 species pairs were studied in Yunqiu Mountain area.The results of variance ratio showed that 20 dominant species overall displayed significant positive correlation.The community structure and species com-position would gradually tend to perfect and stable.The x2-test,Pearson correlation coefficient and Spearman rank correlation coefficient showed that most of the species pairs association did not reach significant level,species correla-tion were relatively loose.And it showed that the shrub community was the stabile in Yunqiu mountain area.Accord-ing to the adaptation way of 20 dominant population to the environment and leading ecological factors aided by PCA sorting,they were divided into two ecological species group,which revealed the dominant species of the region’s ma-j or relationship with the environment.关键词
