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 ,采用集对分析法对各伐区作业模式的综合效益 (经济效益和生态效益 )进行计算和评价 ,为确定伐区生产工艺提供科学的决策依据。计算结果表明 ,“皆伐作业 -全悬索道集材”是目前伐区采集作业的优化作业模式 ,但对常绿阔叶林经营的基本方针是保护 ,生态效益为主 ,从长远利益考虑 ,则“择伐作业 -人力集材”为最优作业模式。
Based on the calulation of economical benefits and ecological benefits of different operational models,which include economical benefits and ecological benefits,wer calulated and evaluated in this paper,which provides the scientific scheme for detemining the prodective etchnology in cutting area.The results showed that the clear cutting operation by suspended cableway sidding is presently the optimum mldol,which is suitable to be used in the north of Fujina province and other areas.But the selection cutting with manual skidding is the opeimum model for long range advantage.
