摘    要:本文根据1985-1990年在天然羊草种群无性系的观测与统分析,在研究羊草种群性系生活周期的基础上,探讨了其种群动态,建立了用转移概率矩阵表示的种群动态模型。通过用两种营养繁殖系数Rv1和Rv2模拟种群密度变化,发现用转移概率矩陈种群动态模型和现存种群营养繁殖系数Rv2预测羊草种群密度。

关 键 词:羊草  种群  无性系  种群动态  生活史

Abstract:The paper, a synthesis based on data generated by an investigation in a clonal Leymus chinensis population for the period 1985-1990,deals with the development patterns and life - cycle behaviour of individual tiller, and the patterns of vegetative reproduction and tiller death, or population dynamics, within clone, The model of population dynamics of the clone was structured in terms of the transition probality matrix. Population deasity was also predicted with Rv1 from past population and Rv2 from present one.
Keywords:clonal Leymus chinensis population  life cycle  population dynamics  population model
