Abstract: he problems of the soil degradation including the content of soil nutrients, humus properties, soil enzyme activity and soil microorganism in pure larch plantations were studied. Mainwhile, the researches of affection of the soil fertility properties in cutting stand, the second rotation stand, and mixture planting were also carried out. Based on analysis of the reasons of causing soil degradation in the pure larch plantations, some appropriate countermeasures of prevention were put forward.
