First, from the status quo of forest resources to speed up the cultivation of backup resources urgently Heilongjiang Province, county forestry land area of 7.48 million hectares, 4.75 million hectares of forest, standing tree total volume of 240 million cubic meters. From the current situation of the forest, the use of natural resources is not sufficient.
