Based on lots of survey and testing, the effect of multifunction wheeled skidder on the physical and chemical properties of trail soil of artificial mixed broadleaf-conifer forest was analyzed quantitatively. The results show that the bulk density of soil increases, the property of keeping water of soil decline, the porosity of soil decreases; the value of soil PH and organic matter. For the nutrient elements, the quantity of nitrogen and potassium increase, and the quantity of phosphorus decrease. The effect of multifunction wheeled skidder on the physical and chemical properties of soil is small when compared to J-50 tractor. The results of study can be used for correctly selecting skidding operation, operation equipment, and reducing the effect of skidding operations on forest soil. At the last, based on the ecological harvesting operation, the corresponding technologies of reducing the damage of soil for timber skidding were put forward.
