摘　　要：首先确定了7种不同的生境格局以及植物的生长规则,并基于此提出分株扩散网络模型,模拟数字克隆植物的分株动态生长的过程。揭示了在分株的不同生长阶段,生境异质性、植物自身的结构特征对分株种群扩散过程的影响,得到分株网络,并对不同处理下的分株种群生长扩散过程进行定量描述,结果表明生境中的斑块分布越密集则分株种群增长速度越快,且不同植物对环境的适应性不同,在富养分斑块产生更长间隔子的基因型探索新生境的能力会更强,而在贫养分斑块产生更长间隔子的基因型更容易获取生境中的有利资源,由此揭示了克隆植物的生态复杂性。The paper determines seven habitat patterns and plant growth rules,and propose ramets distribution network model to simulate the dynamic growth of digitally cloned plants.The effects of habitat heterogeneity and the structural characteristics of the plants on the diffusion process of ramets at different growth stages were revealed.Besides,we obtain ramet network and quantitatively describe the growth and diffusion process of ramet population under different treatments.The results show that the denser the patch distribution in the habitat,the faster the ramets population will grow.Different plants adaptability to the environment differently,and genotypes that produce longer spacers in resource-rich patchesprefer to explore the habitat while the genotypes with longer spacer in the resource-poor patches are more likely to obtain favorable resources in the habitat.
