Assessment of animal skidding and ground machine skidding under mountain conditions

The proportion of animal skidding in forest operations in Heilongjiang forest region increased significantly in recent years. This paper at first demonstrated and analyzed the development of the animal skidding and machine skidding, then, evaluated these two means of ground. skidding currently running in this region both individually and comprehensively under the following criteria: operation efficiency or operation cost, degree of damage to soil and residual stands, accident rate, and natural regeneration. Finally, according to the results of synthetic assessments, classifications of operation conditions suitable to each of skidding measures were recommended quantitatively with considerations of multiple evaluation criteria.
