摘　　要：本文针对我省次生林面积大、资源较为丰富多样等特点,提出了以边缘效应理论来合理经营开发利用次生林资源。采用在效应带、效应岛内栽植针叶树和其它经济植物的方法改造次生林,不仅使次生林的结构得到了调整,功能得到了改善,而且林分达到了速生、优质、高产,从而缩短了针阔叶混交林的形成过程,提高了造林成活率与保存率及林木生长量,取得了显著的经济效益和社会效益。In this paper, the authors advanced the theory of edge effect to manage and utilize the secondary forest resources rationally, in accordance with great area secondary forests and rich resources in our province. Adopted the method for planting conifer and other economic plant in effect zone and effect island to transform secondary forests, in this way, not only regulated the structure and improved the function of secondary forests, but also made the forest stand fast-growth and high-yield, so shorten the time form mixed conifer-broad- leaved forest, increased the survial rate and Preservation rate in forest culture and forest increment, gained remarkable economic and social benefits.
