摘要
林业机械化是实现林业现代化的基础,采运机械化是林业机械化的重要组成部分。黑龙江省是我国的重点国有林区和主要木材生产地之一,研究黑龙江省的采运机械化发展对于实现我国林业现代化具有重要意义。以黑龙江省森林工业统计资料为基础,对其采运机械化的发展变化进行分析。采用主成分分析法,在SPSS软件中定量计算,找出采运机械化发展的5个驱动因素,并认为驱动采运机械化发展的直接原因是生产成本等经济因素,而根本原因在于森林资源状况的变化。最后预测,未来几年黑龙江省采运机械化水平不会发生显著变化。
Forestry mechanization is the foundation of achieving forestry modernization, among which forest harvesting mechani- zation is a key component. As a key forest region of our country, Heilongjiang Province is a major timber producer. It is significant to study the development of forest harvesting mechanization in Heilongjiang for achieving the forestry modernization. In this paper, the development of forest harvesting mechanization in Heilongjiang was analyzed based on the statistics of forest industry. Then five driving factors of forest harvesting mechanization were determined by SPSS software using principal component analysis method. The result showed that production costs led directly to the changes of forest harvesting mechanization, while the fundamental reason is the change of forest resource. At last, the trend of forest harvesting mechanization in Heilongjiang province was predicted that the level of harves- ting mechanization would not change significantly in a few years.
