摘　　要：对南方人工林伐区常用8种采集运作业模式的综合效益进行分析与评价。结果表明:在相同的作业条件下,不同作业模式,其经济效益、生态效益、社会效益以及综合效益均不同。作业模式Ⅱ即油锯采伐手扶拖拉机集材船运木材为最优作业模式,作业模式Ⅲ(油锯采伐索道集材农用车运材)为次优作业模式,建议林业生产决策部门在选择人工林伐区采运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,应优先选择作业模式Ⅱ;在无水路运输条件的伐区,则应优先选择作业模式Ⅲ。Through analysis and evaluation on eight kinds of harvesting and 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 are different, the model Ⅱ has the best comprehensive benefit, being the optimum model for cutting area operation. The second best comprehensive benefit is achieved in model Ⅲ. 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 harvesting and transportation for artificial forest cutting area. The model Ⅱ should have priority to be selected in the cutting area with the condition of waterway transportation. The model Ill should have priority to be selected in the cutting area without the condition of waterway transportation.
