摘　　要：树高曲线是林分生长与收获模型的重要组成部分,是森林经营管理中需要参考的重要统计模型。本研究以湖北省恩施土家族苗族自治州(以下简称恩施州)建始县国有长岭岗林场的日本落叶松人工林为研究对象,以8个应用广泛的树高曲线方程作为备选模型,以不同林龄、不同立地条件、不同密度的固定样地每木检尺数据为基础,基于拟合优度指标选取最优基础模型,构建鄂西山区日本落叶松人工林的单木树高曲线模型。结果表明,8个基础模型的拟合优度均在0.85以上,其中M3、M5模型拟合效果最优且较为接近(R^(2)=0.915),但M3模型对大径级树高预测偏差明显,故选取M5模型为鄂西山区日本落叶松人工林单木树高曲线模型,为其生长量调查及经营管理提供参考。Tree height curve is an important part of stand growth and harvest model and an important statistical model to be referred to forest management.In this study,the Larix kaempferi plantation in Changlinggang Forest Farm of Jianshi County of Hubei Province were taken as the research objects.Eight widely used tree height curve equations were used as alternative models,based on the measurement data of each tree in fixed plots with different stand ages,site conditions and densities.Based on the goodness of fit index,the optimum basic models were selected to construct the individual tree height curve model of L.Kaempferi plantation in western Hubei mountainous area.The research results indicated that,the goodness of fit of the eight basic models were all above 0.85,of which M3 and M5 models had the best fitting effect and were close to each other(R^(2)=0.915),but M3 model has obvious deviation in predicting the height of large diameter trees,so M5 model was selected as the single tree height curve model of L.Kaempferi plantation in the mountain area of western Hubei,providing reference for its growth survey and management.
