抄録

We estimated the amount of forest resources available from Nagano Prefecture from the number of forestry machinery that is social constraints. Firstly, the utilization rate and the productivity of the bucking machinery were calculated from the survey of the number of forestry machines owned. Based on the results, we estimated the number of forestry machinery needed to produce future target of 750,000 m3. In order to achieve the goal, it is necessary to increase more than 60 machines and it became clear that it is a very difficult goal. In addition, it was difficult to produce even if the operation rate was improved. Therefore, it was suggested that the limitation of the available amount by the number of forestry machines is very large
