| Abstract: | This paper describes the natunal forest characteristics of Fraxinus mandshurica, and based on the theory of population variation stand selection of colony is conducted by the selective method of phenotype, and Analysis is conducted by number theory I and sets up mathematical model. The relationship among facters which effects stand productivity and yield, and quantity indexes of colony productivity of different stand is made. |
