摘要/Abstract

摘要： 针对大兴安岭地区塔河林业局不同林型下，不同火烧强度的火烧迹地的森林植被更新及恢复情况进行了调查研究。结果表明：（1）针叶林过火迹地上，落叶松幼苗较少，阔叶树萌条更新强度同火烧程度成正比；火烧前生长有白桦、赤杨的林地上，火烧后阔叶树成为主导树种，林相完全发生变化。（2）重度火烧下有利于天然更新，促使白桦、山杨萌生。中度火烧最初形成以杨桦为优势树种的阔叶林，后逐渐演变为针阔混交林。轻度火烧有利于针叶林的更新。（3）火烧后不同林型下灌木草本植被种类变化不同。从盖度方面来看，杜鹃落叶松林型中林下灌木草本更新最为良好。

Abstract: This paper studied the regeneration and restoration of vegetation in the burned area of different forest types and fire intensities. The results showed that there are few larch seedlings in the burned area of coniferous forest and the sprout of broad-leaved tree is positive related with burned intensity. In the burned area of birch and alder stand, the broad-leaved trees have become the dominant species. Severely burning is benefit for natural regeneration and promoting the sprout of birth and alder. The forest in moderately burned area is mainly composed by birch and alder at first and become mixed forest finally. The lightly burning is benefit for the regeneration of conifer forest. The kind of shrubbery and herbage is different in different forest after fire. The regeneration in the forest of Ass. Rhododendron dauricum，Larix gmelinii is the best.

Key words: vegetation restoration, burned area, natural regeneration
