摘　　要：对河南省不同立地条件下的栓皮栎天然次生林群落生物量进行研究。结果表明,不同土壤类型林分生物量表现为:黄棕壤>棕壤>褐土;不同土层厚度林分生物量表现为:随着土层厚度的加深,林地生物量迅速增加;不同坡向林分生物量表现为:阳坡>半阳坡>半阴坡>阴坡;不同坡位林分生物量表现为:下坡>中坡>上坡。在抚育措施相同或相似的情况下,林分以生长在土壤类型为黄棕壤、土层厚度较深、坡向为阳坡、坡位处于下坡时栓皮栎天然次生林林分生物量最高。Studies were conducted on Quercus variabilis natural secondary forest community biomass under different site conditions in Henan province. The results showed that： Quercus variabilis is resistant barren tree species, but under different site conditions, there is a big difference in biomass. Different soil types stand biomass for them： yellow brown soil 〉 brown soil 〉 cinnamon soil;Different soil layer thickness of the stand biomass is shown as： with the deepening of soil layer thickness forest biomass increased rapidly ; For different slope forest the stand biomass is shown as： sunny slope 〉 halfsunny slope 〉 half shaded slopes 〉 shady slope;For different slope positions the stand biomass is shown as： lower slope 〉 middle slope 〉 upslope. It is shown that, under the same or semblable living conditions, Quercus variabilis natural secondary forest biomass is the highest with the following precomditions： yellow brown soil type, deeper soil thickness, sunny slope, and lower slope positions.
