Abstract:

In this study we collected data of the acreage and tree species of plantation according to the Grain for Green Programs(GGP) in Yunnan Province from 2000 to 2006, and designed the six different schemes for planting and havesting the annual area of forests in GGP from 2007 to 2010. Furthermore, the empirical growth curves for the different planted tree species were developed based on data from national forestry inventory, and they predicted the average growth rate of plantations under various climates and site anditions. These curves were used for the estimating the carbon stock in the living biomass of the forests, in combination of wood density (WD), biomass expansion factors (BEF) and carbon fraction (CF). The prediction shows that the carbon stock in the biomass of forests in GGP in Yunnan will reach to 8.1～8.8, 19.6～25.7, 18.4～33.0, 20.3～34.9 and 23.6～35.4 TgC by the year 2010, 2020, 2030, 2040 and 2050, respectively, and the carbon stock in the biomass in the previous cropland accounts for 33%～41% of all GGPland in Yunnan.
