| Research Abstract |
Most of multi-function forest machines are operated as they travel in forested sites. So, in researching logging operation by them in considerations of forest environments protection of logged sites, it is very important to find out suitable logging method by them to minimize the influence to forest soils. Then firstly, the effects of a layr of limbs left on the working trails were investigated in logging sites and experimental field in forests. It became clear that a cover of limbs held down the damage of the physical properties of forest soils. Secondly logging operation by harvester that is a representative multi-function forest machines were discussed with simulation method. It became clear that if the felling operation by one-man chain saw was combined with logging by harvester in order to decrease the percent of area working trails of harvesters ocupied to total forested area, logging operational efficiency deteriorated fairly in comparing logging only by harvester and the logging method combined with the chain saw operation have problems. When the work of harvester to cover limbs on working trails were added, the deterioration of efficiency was about 30 percent in comparing with the usual logging operation by harvester its work is not performed.
