摘要: 从种群生态学和干扰生态学的角度出发,采用火史重建的方法,研究了大兴安岭北部兴安落叶松种群的稳定性与火干扰的关系。结果表明:研究区内历史上火干扰频繁,平均间隔期为28.9年,火烧强度较低。兴安落叶松依靠较强的耐火力、火后恢复力及自我恢复力具一定的稳定性。种群耐火力与长期火状况密切相关,表现为:低频类< 中频类< 高频类,高强类< 中强类< 低强类。火后恢复力与自我恢复力和最近一次火烧强度及距今时间密切相关:火后恢复力以高强类 >中强类 >低强类;自我恢复力以中强类 >高强类 >低强类。两种火后恢复力都以短期类 >中期类 >长期类。最后指出:兴安落叶松种群稳定持续发展需要适宜的火干扰。

Abstract: This paper, which is from the view of Disturbance and Population Ecology, studies the relation between the stability of Larix gmelini population and the fire disturbance in the northern DaXing AnLing mountain with the method of reconstructing fire disturbance history from live and dead material.The result reveals that:fire disturbance is frequent in the history, and average interval is 28.9 years.Larix gmelini is stable depending on its stronger fire resistance, post-fire resilience and self-resilience.The fire resistance of population is related to the fire disturbance regime, the ranks of different fire regime type are listed follows:low frequency middle severity> low severity, and the rank of self-resilience is that:middle severity> high severity> low severity.Both the sequences of the two resilences are that:short period> middle period> long period.This research concludes that:Larix gmelini needs suitable fire disturbance to keep stability.

Key words: Larix gmelini, Stability, Fire disturbance regime
