摘　　要：该研究应用数理化理论模型Ⅰ的方法,对福建明溪闽楠林窗更新培育基地进行样地调查与数据收集,分析探讨不同立地因子对林下闽楠生长效应的影响。结果表明,影响林窗更新闽楠生长的主要因素依次是坡位、坡向、坡度,且对闽楠生长影响均达到极显著。在闽楠林窗更新过程中,进行坡位、坡向和坡度选择十分必要。By using the quantitative theory Ⅰ model,sample plots investigation and data collection were conducted on the forestation base of gap regeneration Phoebe bournei in Mingxi,Fujian.The growth effect of different kinds of site factors on growth effect of P.bournei was analyzed.The results showed that the dominant factors affecting the P.bournei growth were slope position,aspect,slope.The factors had extremely significant effect on P.bournei growth.In the gaps update process,selections of slope position,aspect and slope are necessary.
