THE ENERGY OF CYCLOBALANOPSIS ELEVATICOSTATA COMMUNITY IN SUBTROPICAL ZONE
亚热带山地突脉青冈群落能量的研究

Based on the measurement of biomass and the rate of its increase, caloric value ofrespective plant organs, energy of standing crop, annual net energy fixation and energyconversion efficiency in Cyclobalanopsis elevaticostata community in subtropical zone at950 m altitude in Fujian Province were determined in 1996. The results showed that thecaloric value of the bark was the highest and the microroot being the lowest among dryweight of plant organs in the community. Total energy of standing crop in the communitywas 852058 kJ m2, of which the aboveground part comprising 87.01%, and theunderground part 12.99%. Yearly net energy fixation was 28 273 kJ m, and energyconversion efficiency was 1 .35% for the community.
