人工林伐区木材运输作业模式选优

对南方人工林伐区的常用4种木材运输作业模式进行综合效益分析与评价.结果表明:在相同的作业条件下,不同木材运输作业模式,其经济效益、生态效益和社会效益以及综合效益均不同.建议林业生产决策部门在选择人工林伐区运材作业模式时应综合考虑其经济、生态和社会效益,在有水路运输条件的伐区,应优先选择船运木材或排运木材;在无水路运输条件的伐区,则应优先选择农用车运材.

Selecting on the Optimum Operation Model of Transportation in Artificial Forest Area

Through analysis and evaluation on four kinds of wood transportation models commonly used in our country's southern artificial forest area,the result shows that under the same operation conditions,the economic benefits,ecologic benefits,social benefits and comprehensive benefits of different operation models of different wood transportation are different.It is proposed that the production decision department of the forestry should consider the economic,ecologic and social benefit synthetically in choosing the model of wood transportation for artificial forest cutting area.Wood transportation by boat or by rafting should have priority to be selected in the cutting area with the condition of waterway transportation.Wood transportation by farm truck should have priority to be selected in the cutting area without the condition of waterway transportation.
