摘要

根据福建省建瓯市 40块毛竹〔Phyllostac hysheterocycla (Carr.) Mitford cv .Pubescens〕林标准地的能量测定资料 ,提出毛竹林生态系统能量动态分室新模型 ,进而对毛竹林各分室的能量进行模拟。结果表明 :所建立的新的分室模型更能反映毛竹林生态系统能量动态规律 ,从而为毛竹林的丰产与稳产提供理论依据。 

Abstract

Based on the energy data from 40 plots of Phyllostachys heterocycla ( Carr. )Mitford cv. Pubescens in Jian 'ou City, Fujian Province, a new compartment model of energy dynamics of P .heterocycla cv. Pubescens ecosystem was built, each compartment energy of above-ground part, litter, under-ground living root, under-ground dead root and total bamboo energy of stand was simulated by the new model. The results showed that the energy dynamic law of the ecosystem was reflected reasonably using the model. Theoretic basis for the high-stable yield of this species was provided.
