Abstract:

Taking Picea asperata plantation in Gansu province as the research object,680 representative sample trees of Picea asperata plantation were selected to study the binary volume equation in this area.The results showed that 12 kinds of volume alternative models by used had good fitting effect.Model 11 and Model 12 are finally determined as the binary volume equations of the artificial spruce forest in Gansu province.Through goodness-of-fit test,this volume model precision met the productive requirement,it can provide scientific basis for forestry investigation,accumulation estimation and scientific management of Picea asperata plantation in Gansu province.

Key words: volume equation, Picea asperata, plantation
