Logging the right way to update or not, is to achieve more and more forest resources, more and more good, green mountains and sustainable use of the key. The western slope of Daxinganling forest area, flat terrain, shallow soil, short plant growth, low growth rate of trees, natural regeneration is good, these are different from other prominent features of the forest area.
