摘　　要：以湖北省泡桐人工林为对象,利用674块泡桐人工林样地数据,通过8种生长模型的拟合对比,选择Logistic方程曲线作为胸径地位级导向曲线的最优模型,并对所建模型和地位级表进行适用性和精度检验。结果表明:采用数式法编制的湖北省泡桐人工林胸径地位级表,精度高、实用性较强,适用于湖北地区泡桐人工林林分的客观评价。Taking Paulownia plantations in Hubei as the object, we used 674 plots data of Paulownia plantation from Hubei for- est inventory data, contrasted eight kinds of fitting growth model, and chose Logistic equation curve as the diameter of the optimal position Guiding Curve model： D= 23.675 5/（ 1＋2.722 9e^-0.0929A）. We established the DBH class table of Hubei Paulownia plantations, and the results were with high accuracy, and practicability for objective evaluation of Paulownia Plantation in Hubei.
