Skidding cost can be divided into fix and variable contents normally. Fix cost stays constant under the same operation conditions. But variable cost has a proportional relationship with skidding distance. in the case of opening-up, the first step in the planning stage is to optimize the forest road density. The optimum forest road density satisfies the minimum skidding cost with minimum forest road density(construction cost of forest road). Therfore the variable cost in skidding operation takes a definite role in caculating optimum forest road density. In this paper, the theoretical examine was carried out, to establish the method of calculating variable cost per unit in skidding operations.
