摘　　要：根据木荷人工林样木的材积V、胸径D和地径D0测定值,采用多模型选优法并配合改进单纯形法研制了木荷人工林一元材积方程V=0.000357D2.18617和地径材积方程V=0.000277D02.115752,据此编制了一元材积表和地径材积表。经检验,这2种数表能够满足生产上的精度要求,可在森林调查中推广应用。Based on the determination of the volume （V）, DBH （D） and ground diameter （Do） of Schima superba, the multiple model selection with the improved simplex method was used to single volume equation （ V=0.000357D^2.18617 and ground diameter volume equation （V=0.000277D0^2.115752, which was applied to establish single entry volume table and ground diameter volume table. The test of the two equation showed they matched the accuracy requirements in production, therefore could be applied in forest survey.
