摘　　要：比较了河南省境内不同立地条件下栓皮栎人工林5个分布区生物量的分配特征。结果表明：黄棕壤上的栓皮栎林生物量最高，为138.63 kg／m2，棕壤其次，褐土上的栓皮栎人工林生物量最低，仅为黄棕壤的72.62％；不同坡向的栓皮栎林生物量平均值大小顺序为西南＞南＞东南＞东北＞北＞西北；不同的土层厚度对栓皮栎林的生物量影响显著，不同土壤厚度的生物量大小顺序为（60～80cm）＞（40～60cm）＞（20～40cm）＞（0～20cm），随着土层厚度的加深，林地生物量迅速增加；不同坡位生长的栓皮栎林生物量有所差异，林分生物量大小顺序为下坡＞上坡＞中坡，但差异不明显；海拔对栓皮栎人工林生物量没有显著的影响，栓皮栎林在海拔700～1300m之间生长状况最好，随着海拔的升高，生物量呈下降的趋势。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 vol-ume the lowest,only 72.62%of yellow brown soil of different slope aspects of Quercus variabilis forest bi-ological 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 bio-logical 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.
