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 to analyse 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.
