原始林不断采伐利用,次生林面积随之增加,(仅黑龙江省占50％以上),充分发挥次生林的生长潜力,对维持和改善自然环境同时对增加木材产量都具有重要意义、理论研究是科学决策的物质基础,从事森林经营的理论研究本身具有指导实践意义。笔者试图用现代生态学观点,分析次生林经营中的几个理论问题,下面将从三个水平:个体、种群和群落水平加以分析。
The use of virgin forest continuously increases the area of secondary forest (only 50% of Heilongjiang Province), and gives full play to the growth potential of the secondary forest. It is of great significance to maintaining and improving the natural environment and increasing the output of wood. The theoretical research is a scientific decision The material basis, the theory of forest management in itself has practical significance. The author attempts to analyze several theoretical issues in the management of the secondary forest from the perspective of modern ecology. The following three levels will be analyzed: individual, population and community level.
