Tiller renewal rate ( rr ) was used to describe the population growth rate on modular level 提出以分蘖更新率r _这一指标来表示无性系构件水平的种群增长率。
2.
The temporal and spatial dynamics of a single species metapopulation is modelled by a model . the stability of spatial distribution of the population and relationships between the stable patchy distribution and migration rates and finite rate of growth of subpopulations are also investigated . finally measures to boost the growth of total population are presented through the model and analysis of the model 通过模型模拟了呈一般缀块分布的单种种群的时空动态.讨论了种群空间分布的稳定性及稳定缀块分布与种群在缀块间迁移率和子种群增长率之间的关系，并由此提出了促进全局种群增长的措施
