| 摘 要： | 利用混交度、大小比数、角尺度3个林分空间结构参数对浙江泰顺天然米槠林进行了分析，结果表明，该林分混交度平均值为0.75，混交程度在中度至强度之间；林分大小比数平均值为0.58，多数林木处于中庸状态，处于优势状态林木多为第I林层林木；林分角尺度平均值为0.65，林木分布格局表现为聚集分布。

| Abstract: | Natural evergreen broad-leaved forest in southern China has important ecological and economic values. To provide reference for forest sustainable management by stand spatial structural adjustments, three parameters, namely mingling index, neighborhood comparison, and uniform angle index, were used to analyze the spatial structure characteristics of natural Castanopsis carlesii forest in Taishun of Zhejiang. The results indicated ted that the average stand mingling index was 0.75 that was between middle degree and intensity degree. The average stand neighborhood comparison value was 0.58, which showed that the majority of woods were in a moderate state. Most woods in dominating state were in I tree layer. The average stand uniform angle index was 0.65, and the trees exhibited a clustered distribution pattern. |
