摘要
依据Harper(1977)提出的构件生物(modularorganism)种群理论,将源于同一地下根茎的每一竹子视为一个构件。把斑苦竹竹子构件无性系种群的生活史小循环划分为8个阶段,用Leslie矩阵表述和预测了四川缙云山该种群的数量和年龄结构变化趋势。结果表明,用Leslie矩阵来预测靠无性繁殖来扩大种群数量的竹类植物的年龄结构和数量动态。
Based on the theory of Harper’s (1977) modular organism population, we considered each bamboo origining the same rhizome as a module, in this paper. The small cycle of life history of Pleioblastus maculata clone population was divided to 8 stages. The dynamics of size and age structure of P. maculata clone population on Mt. Jinyun, Sichuan, were studied by leslie matrix. The results showed that the number of the clone population (in 1992) would increase gradually 8 years later and their age structure would stablize 16 years later. In addition, it was reliable to predict the size change and age structure in the P.maculata population that reproduced by a vegetative propagation methed.
