چکیده
information on the productivity, costs and applications of the logging system is a key component in the evaluation of management plans for the rehabilitation and utilization of caspian forests. skidding and road construction costs are expensive forest operations. determining the optimum forest road network density is one of the most important factors in sustainable forest management. logging method is an important factor to determine the optimum road network density. in this research, in order to determine the optimum road network density, skidding cost and road construction cost were calculated. linear programming model was used in order to reduce the skidding costs and to determine the optimal forest road network density. our aim was to determine the minimum skidding cost for timber jack and clark skidders for different average skidding distance. the results showed that it is less costly if clark skidder is used for skidding. then the optimal road network density at this manner was 8 m/ha.

The optimum road spacing has been studied by many researches. It is an important step of forest road network planning. The goals of this study are determining the optimum road spacing in Kheiroudkenar forest of Nowshahr in Northern Iran and study of effect of kind of skidder on skidding cost and road spacing. Continues time study method was used to determine the production rate of TAF and Timbe...
متن کاملDetermining the Optimum Road Density for Ground Skidding System in Dalak Kheyl Forest-Hyrcanian Zone
Determining the efficient density for forest roads is essential to decrease the costs of skidding and road constructing in forestry plans. In order to estimate the optimal density for road network in Dalak kheyl forest district (Mazandaran Wood and Paper Industries), we calculated the roading costs and hourly costs of Timber jack 450C and HSM 904 skidders. The length of skid trails was measured...
