Abstract:
Based on the spatial series of the shrubby grassland,coniferous forest,coniferous broad leaved mixed forest and monsoon evergreen broad leaved forest in Dinghushan forest,the characteristics of ecological energetics in succesional processes of Monsoon evergreen broadleaved forest have been studied.The layers,leaf area index,the acceptance of radiation energy,gross primary productivity,net primary productivity,leaf biomass,biomass,the amount of litterfall,the standing crop of fallen tree and stand pole,the annual biomass of tree mortality,annual herbivory,annual growth and the standing crop of energy are increasing continuously during the process of succession with an uneven rate.All the indexes of ecological energetics grow faster in the early stage and they are slower in the late stage.A detailed biomass accumulating curve in the monsoon evergreen broad leaved forest succession process is proposed by spatial replacing temporal method.
