摘　　要：[目的]研究马蹄荷树种生长规律,为天然林保护和人工林培育提供理论支持。[方法]采用经典树干解析方法,研究马蹄荷树种胸径、树高、材积、形数的生长变化规律。[结果]幼龄期树高生长较快,10 a后开始下降;胸径生长快速期较长,20 a后开始下降;材积生长一直处于增长期,平均生长量和连年生长量没有相交,都保持快速生长。[结论]马蹄荷在风倒前生长状况良好,适宜在防城港自然环境中生长。[Objective] To research the growth rhythm of Exbucklandia populnea（ R. Br. ex Griff.） R. W. Brown,and to provide theoretical support for the natural forest protection and plantation cultivation.[Method] Stem analysis was carried out by classic trunk analysis method. Growth change rules of diameter at breast height,plant height,volume of timber and form factor were researched.[Result]Plant height grew rapidly at juvenile phase,declined after 10 a. Diameter at breast height was relatively great at rapid growth stage,and declined after 20 a. Golume of timber was at growth stage. Average increment did not associate with current annual increment,which both maintained at rapid growth.[Conclusion]E.populnea grows well before wind fall,and is suitable to grow in the environment of Fangchenggang.
