Research and Development on the Growth Environment of the Young Tree of Pinus koraiensis in Pinus koraiensis-Broadleaved Mixed Forest

Many studies have been conducted on recovering and developing Pinus koraiensisbroadleaved mixed forest, the typical zonality forest on the northern of northeast China. In this paper, the development of the growth environment of Pinus koraiensis young tree on Pinus koraiensisbroadleaved mixed forest is reviewed, which include the effect of some factors, such as stand structure, light, associated tree species, site condition, on the growth of Pinus koraiensis young tree.The authors also put forward some suggestions on futures study.
