Abstract: The composition,diameter structure and productivity of the secondary Castanopsis carlesii forest were discussed in this paper. Within the C. carlesii communities,there are 37 families,61 genera and 76 species of vascular bundle plant,of which,24 families,44 genera and 59 species of arbor and shrub,8 families,10 genera and 10 species of herb,and 5 families,7 genera and 7 species of liana. The stand diameter distribution of juvenile stand appears an inversed “J”form,and that of the half mature forest approximately a normal distribution. The diameter distribution of stand or tree population can be predicted in logistic equation, F =1/(1+ Me-RX), R =2.197 22/(1.989 72 Dg0.852 05 -0.534 29 Dg1.177 47), M =eR0.534 29 Dg1.177 47. The secondary C.carlesii forest has higher productivity.For the 40 years stand,the mean diameter can reach 27.1 cm,the mean tree height 17.0 m,and the tree volume 389.26 m3/hm2.
