摘要:

本文以东北过伐林区汪清林业局为案例,模拟仿真了分类经营、重点生态公益林面积比例对其资源、产业结构的影响;并对择伐面积比例、重点生态公益林所占面积比例进行了灵敏度分析,提出了产业结构调整的优选方案。研究结果表明,木材采运目前仍然是汪清林业局的主导产业;实施分类经营,提高重点生态公益林比例,有利于林分蓄积的增长。

关键词: 产业结构, 森林资源, 分类经营

Abstract:

In this paper, the Wangqing Forestry Bureau was taken as a case of overcutting forestry area in northeast China. Not only the influence of the classified management and proportion of special public area on forest resources and industrial structure were simulated ,but also the sensibility analyses of proportion of selective area and proportion of special public area we carried out and the desirable project of structure regulation was given. Results are as followed: by now, wood logging & transportation still has been the dominant industry of Wangqing Forestry Bureau. It is helpful to increase forest growing by implementing classified management and improving proportion of special public area.

Key words: Industrial structure, Forest resources, Classified management
