Studies on Stand Structure of Castanea mollissima and Edgeworthia chrysantha

Cai Hua (Forestry District of Jinzhai County,Jinzhai 237300)  
Observations and measurements in fixed position on Castanea mollissima and Edgeworthia chrysantha were carried out in three successive years.The results showed that the ecological structure of forest in mixed stand was more complicated and resonable than that in pure stand and the ability to use environment resources in mixed stand was also stronger than that in pure stand.The physical and chemical properties of soil in mixed stand were improved greatly.The photosynthetic rate of Edyeworthia chrysantha in mixed stand was higher than that in pure stand but the transpiration raate was lower which was good for the tree to grow well under stress of drought.
