| Abstract: | Through testing and analyzing the growth conditions,physical indexes,soil factors and meteorological factors of the pure forest of Pinus tabulaeformis and the mixed forest of Pinus tabulaeformis and Quercus mongolica,the results show that the mixed forest of Pinus tabulaeformis and Quercus mongolica has more growth advantage and ecological benefit than the pure forest of Pinus tabulaeformis.The mixed forest can effectively improve the soil water and fertility condition,increase the relative humity of stands and decrease the temperature,so as to enhance the photosynthetic capacity of trees and increase the growth of trees. |
