如何提高森林总生产量,达到本世纪末林业产值翻两番的目标,是当前我国林业建设、也是林业调查规划工作面临的一个重要课题。有人认为通过抚育间伐可达到此目的;也有人认为适度的抚育间伐能够提高木材形质,缩短培育大径材的轮伐期,但不能大幅度增加单位面积木材总净生产量。我们将陆续选登几篇论点不尽一致的文章供大家分析讨论。 How to increase the total forest output and reach the goal of quadrupling the output value of forestry by the end of this century is an important issue facing forestry investigation and planning in our country nowadays. Some people think that this can be done by tending thinning. Some people think that proper tending thinning can improve wood quality and shorten the rotation period for cultivating large diameter timber, but it can not significantly increase the total net timber production per unit area. We will continue to vote for several articles that have different arguments for your analysis and discussion.
