为探讨栓皮栎种群的数量稳定性及恢复能力,采用了静态生命表及Leslie 矩阵模型方法,研究了河南省不同干扰程度下栓皮栎种群的生命进程及其数量稳定性。结果表明干扰影响了其生命进程,但栓皮栎种群可以靠死亡率与林隙的改变维持其稳定性,并通过较强的萌芽特性达到一定的恢复能力。结果还表明应进一步完善Leslie 矩阵以使其能包容进无性繁殖的数据。
In order to explore the quantitative stability and the recovery ability of Quercus variabilis populations, the static life table and Leslie matrix model were used to study the life process and the quantitative stability of Quercus variabilis populations under different disturbance levels in Henan Province. The results showed that disturbance affected the course of their life, but the population of Quercus variabilis could maintain its stability by the change of mortality and gap, and achieve some resilience through strong germination characteristics. The results also indicate that the Leslie matrix should be further refined to make it tolerant of clonogenic data.
