摘　　要：对福州地区台湾相思次生林林隙进行实地调查,共调查10个林隙中的130株边缘木,用威布尔分布模型和正态分布模型分别拟合林隙边缘木的胸径级和高度级分布,并进行柯尔莫哥洛夫和卡方检验,结果表明:福州地区台湾相思次生林林隙边缘木胸径级的多度分布符合W eibull分布和正态分布;高度级的多度分布符合W eibull分布,但不符合正态分布。A field survey was conducted on 130 edged trees selected from 10 gaps of Acacia confusa secondary forests in Fuzhou area,the distribution characteristics of DBH and tree height for the gap edged trees were individually simulated with Weibull and Normal distribution models,and then checked by Kolmogorov and Chi-square tests.The results showed that the distribution of DBH classes of gap edged trees in the A.confusa secondary forests in Fuzhou area followed both the Weibull and Normal distribution models,whereas the distribution of tree height classes only followed Weibull distribution model,but it did not follow the Normal distribution model.
