摘要: 应用分形几何的原理和方法,研究不同光照条件下假俭草的生长格局。结果表明,假俭草具有自相似性的生长过程。不同光照条件下,假俭草具有不同的分形维数和相应的生物量积累规律。生物量积累速率随着分形维数的增大而增大。分形维数同时反映了假俭草的分枝能力和对空间的占据能力。假俭草种群具有依据外界条件而调节生长格局的生态适应能力。
关键词: 光照, 假俭草, 生长格局, 分形维数
Abstract: By using the principles and methods of fractal geometry theory, the growth pattern of Eremochloa ophiuroides was studied under different light conditions. The results showed that Eremochloa ophiuroides had a self-similarity growth process. It had different fractal dimensions and disciplinarian of biomass accumulation under different light conditions. The velocity of biomass accumulation increased with the increasing of fractal dimension value. And the ability of divarication and inhabiting space of Eremochloa ophiuroides was showed by fractal dimension. The clonal population of Eremochloa ophiuroides could adjust growth pattern according to the environment. This is a kind of adaptable ecological policy.
Key words: light, Eremochloa ophiuroides, growth pattern, fractal dimension
