Abstract

In order to better understand the interspecific relationships of dominant tree species in Cerasus subhirtella var. ascendens community and better protect and develop this precious ornamental plant，the research methods of phytocoenology are utilized to study its community in Mount Wuyi，Fujian Province. In the community，the dominant populations are Cerasus subhirtella var. ascendens，Schima superba and Cyclobalanopsis glauca. Taking the dominance as the environmental carrying capacity，calculating the interspecies competition coefficient by percentage of relative dominance values，the interspecies competition among them was studied，and the Lotka-Volterra equation was also used to discussed the competition relationship in the paper. The results showed that after several years’ community succession，the relative dominance of Cerasus subhirtella var. ascendens，Schima superba and Cyclobalanopsis glauca would be 28.65％，62.17％ and 9.18％ respectively，which indicated that Cerasus subhirtella var. ascendens，Schima superba and Cyclobalanopsis glauca should be the dominant population in this community in the future. But Schima superba would replace the Cerasus subhirtella var. ascendens as the dominant population and control the whole community. It was suggested that moderate disturbance and artificial forest gaps be beneficial to the reproduction of Cerasus subhirtella var. ascendens.［Ch，4 tab. 18 ref.］
