摘　　要：对东北地区兴安落叶松林、阔叶红松林和山地云冷杉林三大地带性顶级群落衍生出的主要次生林的生态演替过程规律,以及干扰在次生林演替过程中的作用影响进行了综述。结果显示人为干扰对次生林演替的作用有利有弊,但大部分的自然干扰不利于次生林进展演替,利用好采伐、补植和火烧等人为干扰可以有效地促进次生林的演替进程,次生林演替全周期经营和复杂的自然干扰对东北次生林演替的作用机制是未来进一步的研究重点。Due to the excessive logging in the early stages,the natural forests in Northeast China were damaged to varying degrees,thus various types of secondary forests were formed.With the implementation of Natural Forest Protection Project,high-intensity commercial logging has been banned,so that most of the natural secondary forests in Northeast China have been restored to a certain content,but the whole process is slow.Understanding the succession law of secondary forest,using the ecological function of disturbance,and speeding up the succession process of the secondary forest through forest management measures has become the consensus of degraded secondary forest restoration.In this review,we introduce the ecological succession process of the main secondary forests derived from the three zonal top communities of Larix gmelinii forest,broadleaved Pinus koraiensis forest and Mountain spruce-fir forest in Northeast China,as well as the influence of interference on the succession process of secondary forests.It shows that artificial interferences may have both advantages and disadvantages on the succession of secondary forests,but most natural interferences are not conducive to the succession of secondary forests.Making good use of artificlal interferences such as logging,replanting and fire can effectively promote the succession process of secondary forests.Full cycle management of secondary forest successionandthe mechanism of natural disturbance on the succession of secondary forests in Northeast China is the focus of further research in the future.
