摘　　要：在广东省范围内收集了254块样地资料,建立了广东省马尾松、杉木、湿地松、尾叶桉、藜蒴、软阔类、硬阔类等7个树种(组)的相对树高曲线模型。经检验,7个树种(组)的相对树高模型预估精度相当高, 用于材积估计的总相对误差和平均相对误差均在±1％以内,平均相对误差绝对值都在3％以内,最大误差也不超过±5％。用7个树种资料合并建立多树种混合相对树高曲线模型,分树种进行材积估计检验,效果也相当理想。所建模型可广泛应用于广东各类森林资源调查。The relative tree height curve models of main seven tree species groups in Guangdong Province, that is Pinus massoniana, Chinese fir, Pinus elliottii, Eucalyptus urophylla, Castanopsis fissa, Soft broadleves, Hard broadleves are established by using 254 sample plots in this paper. All models of seven groups have high precision, the total and the mean relative errors for stand volume estimation are between ＋ 1% , the mean absolute relative errors are lower than 3 %. In addition, a species - mixed model is established which works well for stand volume estimation of all seven species groups. All models and be used in various kinds of forest inventions in Guangdong Province.
