【摘要】 在计算各伐区作业模式的经济效益指标和定位测定由诸作业造成的土壤肥力和蓄水保土等指标变化量的基础上 ,采用多目标决策和层次分析等方法 ,定量计算各伐区作业模式的综合效益 (经济效益和生态效益 ) ,为确定伐区生产工艺提供科学的方案。计算结果表明 ,“皆伐作业 -全悬索道集材”作业模式是伐区采集作业的优化作业模式 ,这一结论适合类似试验条件的林区借鉴。更多还原

【Abstract】 Based on the calculation of economical benefits and ecological benefits of different operational models,and used of Multi-objectives Decision and Analytic Hierarchy Process,the comprehensive benefits of different operational models,which include economical benefits and ecological benefits,were calculated in this paper,which provides the scientific scheme for determining the productive technology in cutting area.The results showed that the clear cutting operation by suspended cableway skidding is the optimum model,which is suitable to be used in the north of Fujian province and other areas.更多还原
