| 摘 要： | 森林的定量模型研究一直是许多林业工作者感兴趣的问题.该文通过建立林分平均高与平均胸径、林分平均株数与平均胸径的一般空间分布模型,导出了一般林分蓄积量的求算公式.而这一过程没有把经营管理措施,如择伐作业这一限制因子进行综合考虑.该研究首次提出了基于林木生长量的限制因子与基于市场需求为约束条件的模型,使择伐不仅改善了林分的空间结构,同时也满足了市场的需求,产生了最大的经济效益,使森林实现可持续经营.

| Abstract: | Research on forest quantitative models is always focused on by forest professionals.A common formula of stand volume was deduced by establishing spatial distribution models of average diameter with average height of a stand,and tree number of a stand with average diameter,with no consideration of management practices such as the limiting factor of selective cutting.A model with constraint conditions based on limiting factors of stand increment and market demand was put forward in this paper.This model can not only make the method of selective cutting improve stand spatial distribution,but also meet the market demand,and therefore bring maximal economic benefits and realize forest sustainable management. |

| Keywords: | forest management optimal selective cutting spatial distribution model systematic engineering systematic model |
