我省次生杂木林面积很广,约占现有林地总面积的50%,类型复杂,蓄积量低,亟待抚育改造。为发掘次生林的生产潜力,扩大森林资源,调整林种与树种的布局,发挥森林对环境的保护作用,从1963年起省林科所与建德县林场等单位协作进行大面积的次生杂木林抚育改造工作,设立固定标准地定期进行观察,时隔十年已显示出抚育改造的良好效果,现总结如下:
The secondary woodland of our province is very large in area, accounting for about 50% of the total area of the existing woodland, with complicated types and low stock volume, which needs to be nurtured and rebuilt urgently. In order to explore the potential of secondary forest production, expand forest resources, adjust the layout of forest species and tree species, and play a role in protecting the environment. Since 1963, the Provincial Forestry Bureau and the Jiande County Forest Farm collaborated to carry out large- Wood forest tending and reform work, set a fixed standard to regularly observe, after a lapse of ten years has shown the good effect of tending and reform, are summarized as follows:
