我之所以提出这个论点,是有个前提。一是必须走以内含扩大再生产的道路;二是以35亿立方米能采伐利用的森林资源为基数。主要目的是要实现高质量、高蓄积量、高生长量,一反过去的只重视数量,忽视质量的指导思想。这除了改变由粗放经营向集约化经营转变的同时,也请林学家在技术措施上,例如:透光伐、除伐、修枝、间伐等给予研究,使之培育出的林木尖削度最小,圆满度最大,上下一样粗的铅笔型的立木。也请育种学家予以研究,使生长慢,但材质优良,适应性强的树种,能加速生长,例如
The reason I made this argument is that there is a premise. First, we must take to include the road to expanding reproduction; the second is to 3.5 billion cubic meters of forest resources can be harvested from the base. The main purpose is to achieve high quality, high volume, high growth, an anti-past emphasis on quantity, ignoring the quality of the guiding ideology. In addition to changing the transition from extensive management to intensive management, it also requires that forest scientists make researches on technical measures, such as translucent cutting, deforestation, pruning and thinning, so as to minimize the degree of forest tapping , The highest degree of completeness, up and down the same thick pencil-type legislation wood. Breeders are also asked to study to slow growth, but good material, adaptable species, can accelerate growth, for example
