To get more informain about the impacl of lhe Grain for Green Program on soil organic carbon pol. ,soil samples were clele and ase also .from the fir forest in Snjingu lownship, Xingyi mnicipali .Guihou Province, icludin cmpland and six slands wih the difefen age . The resuht show that the soil buk densiy dereses wih stand age by an anmal raule of4. 27% in 0 ~ 60cm layer. The soil bulk density icrerses wih the deep of sol layer. The soil onganic cabhon suornge in fir foretis decraes wih sand age by an amal rate of9.27% in the first 5 years afer afortatio and icrses by an anmual rate of8. 44% from 6 lo 11 years. Bu the soil organie carhon suonge in he fir forest has nol egained that level in frmland at the 11 yer afer aorertitro The soil organice carbhon stornge in fir forets deres with the deep ouf soil layer.
