The community biomass and its allocations in each of the DBH class in tree layer of five forest types,including Pinus massoniana forest(PM),Pine and broad-leaved mixed forest(PBM),Subtropical evergreen broad-leaved forest(SSEB),Ravine evergreen broad-leaved forest(REB) and Montane evergreen broad-leaved forest(MTEB),were studied in Dinghushan Nature Reserve(DNR).Based on biomass regression model,community biomass was estimated by measuring all trees with DBH≥1cm.The results showed that standing biomass density in REB,MTEB,SSEB,PBM and PM in the latest investigations were 472.9 t.hm-2,165.1 t.hm-2,290.4 t.hm-2,164.1t.hm-2 and 22.5 t.hm-2,respectively.The allocation of community biomass in each DBH class in the different forest investigation presented three distribution trends,which were the decreasing distribution,the inverse bell distribution and increasing distribution.The characteristics of biomass allocation in each DBH class in DNR were similar to those in other regions.
