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, according to the characteristics of large secondary forest area and abundant and diverse resources in our province, the paper proposes to use the edge effect theory to rationally develop and utilize secondary forest resources. The transformation of the secondary forest by means of planting conifers and other economic plants in the effect zone and the effect island not only adjusted the structure of the secondary forest but also improved the function of the secondary forest and achieved fast growing, high quality and high yield, thus shortening the coniferous and broadleaf The formation of mixed forest, improve the survival rate and survival rate of afforestation and forest growth, and achieved significant economic and social benefits.
