| 摘 要： | 以滇中地区磨盘山华山松次生林为研究对象,在3种林龄(15、30、40 a)华山松林分中分别设置1 hm2的样地,利用混交度、角尺度和大小比数等空间结构参数研究其林分结构特征,并对林分胸径曲线进行拟合.结果表明:不同林龄华山松次生林的径级分布特征不同,其中15 a华山松林为"单峰型"的径级分布,而30、40 a华山松林乔...

| Abstract: | With Pinus armandii forest in Mopan Mountain in central Yunnan as the research object,three types of forest age(15a,30a and 40a)were set samples with 1hm 2 respectively,and the structural characteristics of forest stand were studied by using the spatial structure parameters such as mingling,uniform angle index and dominance,the DBH curve was fitted.The results showed that the diameter classes distribution of P.armandii secondary forest of different stand ages presented different characteristics,among which the diameter distribution of the 15-year-old P.armandii forest was“single-peak type”,while the diameter distribution of the 30-year-old P.armandii forest and the 40-year-old P.armandii forest layer was“double-peak type”.The common indices were used to fit the DBH distribution,and the fitting results showed significant correlation.The unitary structural parameters and binary structural parameters of P.armandii plantation can describe the succession of forests.The binary structural parameters can indicate the process of community succession. |
