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 700~1 300m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 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.
