培育速生丰产用材林是加速林业现代化建设,扩大森林资源,尽快解决木材供需矛盾的一项战略措施。为保证造林总体规划设计质量,实行科学造林、集约经营、缩短木材生产周期、提高经济效益,因此,在速生丰产用材林造林总体规划设计中,通过土壤、植被专业调查来划分适宜营造速生丰产用材林的立地类型是这项工作的关键项目。 Cultivating fast-growing and high-yield timber forest is a strategic measure to accelerate the modernization of forestry, expand forest resources and solve the contradiction between supply and demand of timber as soon as possible. In order to ensure the overall planning and design of afforestation, afforestation and intensive management should be carried out to shorten the period of wood production and increase economic benefits. Therefore, in the overall planning and design of fast-growing and high-yield timber plantation, Site type is the key item of this work.
