近年来,为了恢复和振兴黑龙江省林业,各林业局在营林、多种经营和综合利用等方面都作出了巨大努力,已开始出现好势头。但由于木材产量过高,尤其是计划外采伐量过大,林业危困的状况很难在短期内扭转过来。为了改变这种状况,为采取相应对策提供依据,本文以森工系统赖以生存的森林资源为基础,采用系统动态学的方法模拟不同采伐量下的资源变动规律,从而提出合理的采伐量,并指出超计划采伐可能造成的恶
In recent years, in order to restore and rejuvenate the forestry in Heilongjiang Province, various forestry bureaus have made great efforts in silviculture, diversified management and comprehensive utilization, and have started to enjoy good momentum. However, due to overmuch timber production, especially unplanned harvesting, it is difficult to reverse the situation of forestry crisis in a short period of time. In order to change the situation and provide the basis for the corresponding countermeasures, this paper, based on the forest resources on which the forest engineering system depends, uses the system dynamic method to simulate the resource variation under different harvesting levels, And pointed out that over-planned logging may cause evil
