东北阔叶红松林区,为我国重要的林区之一。以红松为主所组成的针阔混交林,每年为国家生产着大量的木材及其他林产品,供应社会主义建设的需要。由于木材生产量的不断增加,采伐迹地不断扩大,森林更新任务逐年上升,出现了更新赶不上采伐的现象。怎样解决阔叶红松林区采伐与更新之间的矛盾,迅速地扩大森林资源,保证永续利用,并充分发挥其水利及防护作用,是我国林业科学工作者当前重大的研究课题之一。 阔叶红松林应该采用怎样的采伐与更新方式,在我国林学界中,曾根据红松(Pinus
Broad-leaved Korean pine forest area, one of China’s major forest areas. Coniferous and broad-leaved mixed forest composed mainly of Korean pine trees produces a large amount of timber and other forest products for the country each year and serves the needs of socialist construction. Owing to the continuous increase in the production of timber, the scale of deforestation has been continuously expanded and the tasks of forest renewal have been on the rise year by year. There has been an update on the phenomenon of logging failure. How to solve the contradiction between cutting and regeneration in broad-leaved Korean pine forest, rapidly expanding forest resources, ensuring sustainable use and giving full play to its water conservancy and protection are one of the major research topics for forestry scientists in our country at present. Broad-leaved Korean pine forest should be used what kind of logging and regeneration methods, in China’s forestry sector, according to Pinus thunbergii (Pinus
