摘　　要：在JABOWA树木最优生长模型意义下,研究树木胸径与树高的经验公式h=137+αd-βd2,在无需求dmax和hmax的条件下,应用最小二乘法给出参数α、β的参数估计公式,应用于白桦优良种源的选择,建立了显著性的回归方程。According to the JABOWA forest growth model,the experimental formula of tree height and diameter at breast height （ h=137＋αd-βd^2） was studied. To avoid the derivation calculus of dmax and hmax,the parameter estimation formula was given by the least square procedure. Then the experimental formula was applied to the selection of superior provenance of Betula platyphylla,and a regression equation was established.
