Abstract:

In this paper, the aboveground biomass allocation ratio and regional distribution of three species of plantation tree species (Acacia mangium, Hevea brasiliensis and Eucalyptus spp.) were investigated in seven cities and counties in Hainan Island. The proportion of aboveground total biomass allocation of the three species of plantations was basically followed by dry wood > branches > leaves > dry bark, and the trunk dominates. Based on the consistent diameter of breast diameter, the total biomass of plantation trees in different regions of the tropics was significantly different. The total biomass of A. mangium was between 51.06-179.25 kg, and the value in Baisha was the largest. The total biomass of H. brasiliensis was between 48.42-173.15 kg, the value in Lingshui was the largest. The total biomass of Eucalyptus spp. was between 43.06-228.11 kg, and the value in Danzhou was the largest. The proportion of biomass allocation in the same tree species in different cities and counties was very different. The trunk biomass of A. mangium, H. brasiliensis and Eucalyptus spp. was 48%-78%, 35%-78% and 48%-85% of the aboveground biomass respectively. Greater contribution of tree trunk biomass resulted in higher aboveground biomass. The results of this study would provide basic data for rational management of plantation resources in tropical areas.
