| Abstract: | Three kinds of secondary forest population structiure and succession syndynamics of Shennongjia of Hubei province are analyzed, which used the methods of importance value,tree stratifical frequency and tree stand class. Conclusions show. the communities of Abies fargesii, pinus armandii are stable community types. They have rational structure of conmmunity,they are terminal communities under their bioclimate. But, Betula albo-sinensis community is not stable community, it is a stage of community succession. It will be replaced by theropencedrymion in which pinus armandii is constructive speeies . |
