摘　　要：次生林多为幼壮林,常以阔叶树种居多,林相混杂,乔木、灌木混生,生长率较低,材质不良,利用价值受到一定影响。随着造林规模的不断增加,速度的加快,人工林面积逐步扩大,次生林面积逐渐减少,森林资源结构发生了很大变化。在人工林资源中红松占有一定比例,如何保障红松的正常生长,是个亟待解决的问题。文章针对退化次生林诱导恢复红松阔叶混交林的技法进行分析和总结,具体内容包括诱导恢复原则、诱导恢复技法和严格质量监管等,以期为加速相关技法的推广应用提供借鉴。Most of the secondary forests are young and strong forests,which are often dominated by broad-leaved trees.The forests are mixed,and the trees and shrubs are mixed.The growth rate is low,the material is poor,and the use value is affected to a certain extent.With the increasing scale and speed of afforestation,the area of planted forests has gradually expanded,the area of secondary forests has gradually decreased,and the structure of forest resources has undergone great changes.Pinus Koraiensis accounts for a certain proportion of plantation resources.How to ensure the normal growth of Korean pine is an urgent problem to be solved.This article analyzes and summarizes the techniques of induced restoration of Pinus koraiensis broad-leaved mixed forests in degraded secondary forests.The specific contents include the principles of induced restoration,induced restoration techniques and strict quality supervision,etc.,with a view to providing a reference for accelerating the application of related techniques.
