Abstract: Based on a 2×2 of contingency table,using of variance ratio (VR),x² and the association coefficient (AC),the interspecific association of 10 major tree populations in the community of Cerasus subhirtella var.ascendens were analyzed.The result showed negative correlation of the association among 10 dominant tree populations in the C.subhirtella var.ascendens community; 4 species-pair and 3 species-pair were obviously positive association and slightly association respectively; the value of VR,x² test and AC were similar,which proved that the characteristic of interspecific association was obvious independency and weak correlation all over the community.The interspecific association was friable or negative,which indicated that on the one hand the community was in the stage of secondary forest and on the other hand it may be related to the ecological characteristic of investigated species.Based on the results,it can provide scientific information for design of an appropriate conservation strategy andutilization plan for C.subhirtella var.ascendens.
