随着森林的开发利用,我国原始森林资源的保有量日趋减少。剩余的多处于难以开发的高山陡坡地带。据有关调查资料表明,目前我国黑龙江省木材蓄积量近三分之一处在高山陡坡上。我国东北林区,高山陡坡上生长的树木高大,材质优良,而且多为成熟林或过热林。因此,如何开发利用这部分森林资源,是一项追在眉睫的任务。 With the development and utilization of forests, the stock of primary forest resources in our country is decreasing day by day. Much of the remaining is in hard-to-reach mountain steep slopes. According to the survey data show that at present, nearly one-third of China’s timber stockpile in Heilongjiang Province in steep slopes. Trees in northeastern China and steep slopes of high mountains are tall and of good quality, mostly mature or overheated. Therefore, how to develop and utilize this part of forest resources is an urgent task.
