摘　　要：首先分析了北京八达岭林场元宝枫人工林林分的直径分布;然后利用Weibull分布进行直径拟合,并对拟合结果进行X2检验;最后用角尺度方法分析林木分布格局。结果表明:该林分直径分布呈现不对称的双峰山状曲线,且不符合Weibull分布,林分内林木的分布格局为团状分布。The Acer truncatum plantation structure in Badaling Forest Farm in Beijing was studied in this paper. First, stand diameter distribution was analysed. Second, we fitted the stand diameter distribution using Weibull distribution, and did Chi- square test. Last, the uniform angle index was used toanalyse distribution pattern of the stand. The result showed that the stand diameter distribution shows a bimodal hill - shape curve, and does not accord with Weibull distribution. The distribution pattern of the forest is reunion distribution.
