毛竹林能量分配的研究

STUDY ON ENERGY DISTRIBUTION OF PHYLLOSTACHYS HETEROCYCLA CV. PUBESCENS FOREST

对毛竹丰产林中标准竹各组分样品如秆、枝、叶等的干重热值测定 ,获得能量现存量 ,建立了“金字塔形”和“倒金字塔形”的能量结构 ,预测和控制能量流动过程 ,指导生产经营 ,充分挖掘毛竹林生态系统潜力。

t\; By analyzing the biomass and the energy of the bamboo forest and their mutual relation, the results show that the energy storage is 161603.1 kJ/m 2,amounting for 99.3 percent of the Phyllostachys heterocycla cv. pubescens community. The layer-distributed structure of the energy shaped in the pyramid and reverse pyramid are established. With the use of the energy structure, the energy flow can be predicted and controlled to guide production management and to tap the potential of bamboo forest ecosystem fully.
