| 摘 要： | 利用聚集指数、树种多样性混交度、大小比数等3个林分空间结构参数对滇中地区滇油杉混交林空间结构进行分析，结果表明：林木空间分布格局表现出以最近邻木3株及以上为均匀分布；林分树种多样性混交度为0．2322，混交程度较低，以弱度混交为主，阔叶树种混交程度高于针叶树，滇油杉零度混交明显；林木大小比数平均为0．52，变动小较为稳定，竞争处于中庸状态，滇油杉大小比数分布较均匀，其他组成树种分化程度差异较大，华山松和旱冬瓜处于竞争优势。

| Abstract: | The stand spatial structure of Keteleeria evelyniana mixed forests in central part of Yunnan Province was studied by means of three parameters including the aggregation index,tree species diversity mingling degree and the tree neighborhood comparison ratio.The results showed that the stand spatial distribution pattern for more than three nearest neighbor trees was uniform.The average species diversity mingling degree of the stands was 0.232 2,indicating the low mixing degree.The mingling degree of deciduous... |
