Abstract:
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.
Key words: comprehensive benefits, light-duty cableway skidding, road-cutting skidding, control experiment
