Abstract: Different indices were used based on a 2?2 contingency table to determine the interconnection of the 15 main tree populations of Abies yuanbaoshanensis community in 25m2,50m2 and 100m2 size quadrates.The results showed that the quadrates of 100m2 could exactly display the character of connection between main tree populations and whole community.There was positive correlation among main tree populations in general.But most pairs of main tree populations displayed either positive or negative correlation.A few pairs displayed significant or more correlation.The interconnection of main tree populations was associated with the ecological character of the species.
