Abstract: Stand volume growth was different in different regions due to the variations of tree species,stand condition,forest age,density and forest management etc.Single wood growth models and growth and yield projection models focused on a special plot or small area,and were limited in application of spatial scale extension due to tree species composition,stand quality and competition.Stand volumes of different tree species and stand ages in different regions were the key factor in forest carbon estimation.This paper simulated the stand volume growth curves of five primary forests in China,based on the sampling plot data of national forest resource inventory.The results showed that the best applicable theoretical growth equation for Oak is Richards,Logistic for Larix,Richards and Korf for Masson pine,Birch and Chinese fir;the stand volume of Birch,Oak and Chinese fir at high latitude showed higher value than lower altitude obviously;the stand volume of Masson pine at lower altitude showed higher value;and there was not significant difference with elevation for Larix.The Oak in central China,Masson pine in southwestern region,Chinese fir in Southern China,Birch in northwestern region and Larix in northeastern region showed higher stand volume than other regions.Furthermore,average stand volume and volume growth rate of natural forest of Oak,Masson pine and Larix were higher than the plantations,which was contrary for Chinese fir.These results could be applied to the accurate estimation of forest carbon sequestration and the projection of future potential carbon sequestration.

Key words: stand volume growth, theoretical growth model, Larix, Masson pine, Oak, Birch, Chinese fir
