Abstract: The distribution characteristics of biomass of 5 distribution areas under different site conditions in Henan province were compared.The results showed that in yellow brown soil Quercus variabilis forest biological volume is the highest at 138.63 kg/m²,lower in brown soil variabilis plantation biological volume the lowest,only 72.62% of yellow brown soil of different slope aspects of Quercus variabilis forest biological volume average size order present such an as Southwest>South>Southeast>Northeast>North>Northwest;different soil layer thickness has significant effects of Quercus variabilis forest biomass,biomass of different soil thickness size order:(60~80cm)>(40~60cm)>(20~40cm)>(0~20cm),with the deepening of soil layer thickness forest biomass increased rapidly;different slope bit growth of Quercus variabilis forest forest points biological volume has differences,The stand biomass size order:lower slope>middle slope>upper slope,but differences are not obvious;elevation on Quercus variabilis plantation biological volume has no significantl effect,variabilis forest at elevation of 700～1 300m growth status is best with elevation increase,biological volume has a declining of trend.
