Abstract:The energy storage and distribution were studied in the 11-year-old Chinese fir plantations in Huitong, the central production area and Zhuting, the expanded cultivation area based on the biomass and thermal value of try matter. The result showed that the the amount of existing energy in Chinese fir plantation of Huitong area (12406×108-14733×108J/hm2) was significantly higher than that in Zhuting (9294×108-10894×108J/hm2), suggesting the stand condition and climate play a critical role on the energy accumulation in Chinese fir plantations. Besides, the amount of existing energy in both Chinese fir plantation areas decreased with increasing density in a certain range of stand density, mainly due to the reduced existing energy of the trunk capacity, whereas the amount of existing energy of branches and leaves maintains at a stable state. The allocation of the energy to the different componentsof the tree was different, ranked with decreasing order: stem, roots, leaves, and branches. The energy distribution ratio in Huitong is different from that in Zhuting, e.g. the for both planations, for energy allocated into stem was 56.8%-61.2% in Huitong plantation, which was higher than that of 47.0%-53.5% in Zhuting, while in leaves, the allocation ratio is much lower in Huitong (22.2%-25.9%) than that in Zhuting (28.3%-34.2%). For the spatial distribution of the amount of existing energy at the stand level, most of existing energy was distributed at the soil surface and 2/3 height of the canopy above the ground, where was regarded the most important places for the exchange of substances and energy including water, light, gas and heat in the surrounding environment in forest. Results indicated that: (1) where there is the most urgency in supply of water and nutrients, there is the largest gathering of energy flows at the ecosystem level, and (2) for the 11a stand, there were some factors not suited to the growth of Chinese fir plantation in Zhuting area, in terms of micrometeorologic factors and stand conditions compared with Huitong area, the central area of China fir plantation.
