Abstract：In order to know the succession and renovation process of C.carlessii forest community at cut-over land,based on community investigation of three sample plots in field and calculation key value,the community structure characteristics of C.carlessii Forest under different regeneration patterns at Sanming in Fujian Province are analyzed.The results showed that 13 families,16 genera and 20 trees species were natural regeneration(N.R.),5 families,6 genera and 6 trees species were artificial measures promoting regeneration(A.M.P.R.),1 family,1 genera and 1 specie are artificial generation(A.R.).The effects of DBH of different regeneration patterns of C.carlessii forest are as following: trees of small DBH are more than trees of big DBH in N.R.stand;trees of big DBH are more than trees of small DBH in A.M.P.R.stand;trees of small and big DBH are less than trees of middle DBH in A.R.stand.Spatial distribution of different regeneration patterns C.carlessii N.R.stand has a tendency increasing progressively from the upper to the lower.A.M.P.R.stand tends to normal distribution.N.R.stand is subject to normal distribution.The species richness in different regeneration patterns of C.carlessii forest is N.R.stand>A.M.P.R.stand>A.R.stand in turn.
