栓皮栎种群的生命进程与稳定性研究

A Study on the Life Process and Stability of Quercus variabilis (Fagaceae) Population

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。

To discuss the numeric stability and recovery ability of Quercus variabilis Population, this paper analyzed the population's process and numeric stability at different disturbed degrees in He'nan province, using the stationary life table and Leslie matrix. The results showed that disturbance had affected the population's life process. But the Q.vareabilis population could maintain its stability depending on the changes of mortality rate and forest gap; and could have certain recovery ability through the strong asexual generation. The results also show that the Leslie matrix must be further studied including asexual generation data.
