摘要: 以内蒙古大兴安岭兴安落叶松林火烧迹地为研究对象,采用空间代替时间研究方法,分析比较了不同火烧强度、不同林型、不同更新方式下兴安落叶松林群落恢复过程中乔木更新状况的差异。结果表明:火干扰对乔木的天然更新有一定的促进作用;恢复过程中很长一段时间,白桦更新苗的年龄、高度、基径等指标在群落中都处于优势地位;3种不同更新方式下,乔木更新密度均大于对照样地,并呈现出天然更新>人工更新>人工促进更新的趋势。

关键词: 兴安落叶松林, 火烧迹地, 植被更新

Abstract: The Larix gmelinii forest burned areas were studied in terms of different fire years,different fire intensities,different forest types and different update modes.The natural regeneration conditions were observed and researched in 2013.The results showed that fire disturbance has a promoting effect on the natural regeneration of trees.In the stage of restoration,the age,height,basal diameter and other indicators of birch seedlings are in a dominant position in the community.The density of seedlings in three different update modes in burned areas are greater than unburned area and showed a ranking of 2003S-N>2003S-A>2003S-M.

Key words: Larix gmelini forest, burned area, plant regeneration
