摘　　要：利用海南省1998年、2003年和2008年森林资源连续清查中复查的759株马占相思保留木、42个马占相思实测样地资料,研究建立了马占相思胸径生长率、材积生长率和林分材积生长率模型。结果表明:研建的模型拟合效果良好,无明显系统偏差;建立的马占相思胸径生长率模型预估精度达91%以上,一元和二元林分材积生长率模型预估精度均在98%以上,可为以后海南开展各类森林资源调查估算马占相思生长量提供参考依据。Based on the data of 759 Acacia mangium reserved trees and 42 Acacia mangium sampled plots from CFI in 1998, 2003 and 2008 in Hainan Province, the models of DBH （ diameter at breast height） growth rate, volume growth rate and stand volume growth rate of Acacia mangium were established. The results showed that the model fitted well, and no obvious systematic deviation obtained. Established Acacia mangium DBH growth rate model has.a prediction accuracy of more than 91%, and single and binary stand volume growth rate models have a prediction accuracy of more than 98%. The established models in this paper could provide a reference for the future forest resources investigation and estimation of Acacia mangium growth in Hainan.
