Development history, conception and research method of forest biomass were explained. The impacts of forest management, mixed plantation, tree density were summarized: the forest biomass of successive plantation decreases generation after generation; forest is intermediately cut, its total biomass will be decreased, but the forest quality will be raised; mixed plantation is favorable for total forest biomass; forest biomass increases with increasing forest density in a certain density range, and the biomasses of different density forests will finally be closed to a constant with the forests sufficiently grow. Finally, authors pointed out the research tendency of forest biomass.
