轻型索道集材与开路集材三大效益对比分析

为了研究科学合理的生态采运技术,在邵武二都林业采育场开展轻型索道集材与传统盘山开路集材方式的对照试验。以122-1-3伐区972m3的出材量计算,人工费按每工每日100元计,则索道集材的单位成本为104.65元·m-3,可比开路集材单位成本148.44元·m-3节约29.50%。随着人工费的增加,按每工每日80～140元计,开路集材成本增加明显,单位成本差额为34.47～67.03元·m-3。通过生态、经济与社会效益的比较分析,轻型索道集材优势明显,是一种有利于资源、环境、经济和社会可持续协调发展的生态集材作业模式,在当前劳动力成本剧增情况下,展望轻型索道集材在木材生产技术中的广阔应用前景。

Three Benefits Comparison on Skidding Methods of Light-Duty Cableway and Road-Cutting

In order to study scientific and reasonable ecological skidding technology,the control experiment including light-duty cableway and tranditional winding road-cutting methods were implemented in Shaowu Erdu Forestry Farm.The unit cost of cableway skidding is 104.65 yuan·m-3,which is calculated base on the labour’s hourly fee of 100 yuan and the material quantity of 972 m3 in cutting area of 122-1-3,compared with 148.44 yuan·m-3 in traditional road-cutting skidding,the cost can be saved about 29.50%.With the increase of labor charges from 80 yuan to 140 yuan per day,the variance of unit cost will rise obviously from 34.47 yuan to 67.03 yuan.Through analysis and comparison between ecological benefits,economic benefits and social benefits,the light-duty cableway skidding method has obvious advantages,which is a ecological harvesting operation mode benefit to resources,environment,economy and social sustainable development.With the increase of labour charges in current,the wide application prospect of light-duty cableway skidding method in timber production technology is prospected.
