摘要
以”空间推时间，横向导纵向”方法，建立了格氏栲种群标准生命表、生殖力表，在此基础上运用Ｌｅｓｌｉｅ种群增长模型，预测了格氏栲种群的动态增长过程，揭示了格氏栲各龄级植株的动态规律；同时采用特征根理论方法，分析格氏栲种群稳定性，并模拟格氏栲种群的可能变化．结果表明：该区格氏栲为缓慢增长型种群，总体上保持相对稳定状态，老龄阶段对干扰不敏感，种子和生长阶段对干扰有较大敏感．讨论认为。
In this paper,the standard life table of Castanopsis kawakamii population is founded according to premise of 'space deducing time” method.Based on the static life table,fecundity schedule of C.kawakamii population and the dynamic process of the population was predicted using Leslie population model.The dynamics of plants of each age class was expounded.Moreover,population stability of C.kawakamii was analyzed by the theory of characteristic root and the probable changes in C.kawakamii population were stimulated.The results show that the C.kawakamii population in the natural reserve is of low increasing type and the population is relative stable.The seeds and growth period are more sensitive to disturbance and old age tree stages are less sensitive to disturbance in the population life cycle,which can provide theoretical basis and information for C.kawakamii population protection and management.
