Growth and Ecological Reflection of Mixed Forest of Pinus Massoniana

Growth,biodiversity of stand,physical chemical properties of soil of mixed forest of Pinus massoniana Elaeocarpus sylvestris,mixed forest of Pinus massoniana Castanopsis fissa,pure forest of Pinus massoniana were studied.Result shows that growth increment of tree height,DBH volume increase significantly after mixing of Pinus massoniana,Elaeocarpus sylvestris Castanopsis fissar;species and numbers of plant of mixed forest of Pinus massoniana all increase;biodiversity is richer than that of pure forest of Pinus massoniana;soil physical chemical properties of pure forest of Pinus massoniana improve significantly.
