Study on interspecific association of main populations in arborous layer of a Tsuga tchekiangensis community in Wuyishan National Nature Reserve of Fujian Province
The interspecific association of main populations in arborous layer of a Tsuga tchekiangensis community in Wuyishan National Nature Reserve, Fujian Province was analyzed by means of χ2-test and some indexes including association coefficient (AC) , Ochiai index (OI) , Jaccard index (JI) and Dice index (DI). The results showed that the overall association of the 10 main populations of this community was not significantly correlated. The interspecific associations between most of species-pairs were also not obviously correlation. But a few species-pairs had significant association, such as T. tchekiangensis-Illiciun minwanense, T. tchekiangensis-Eurya brevistyla, E. brevisiyla-Enkianthus quinqueflorus, E. hrevistyla-Illicium minwanense and so on.
