利用混交度、大小比数和角尺度3种结构参数，结合树种组成，对湖北桂花林场4块苦槠混交林样地的林分空间结构进行分析。结果表明，苦槠为优势树种，多单种聚集生长，其他树种强度混交、极强度混交的比例大；枫香在大小分化上占有一定的优势，其他树种则分化严重；从林木水平空间格局上来看．该试验地树种分布格局以团状分布为主。

Abstyact： Stand spatial structure of four Castanopsis sclerophylla mixed forest plots in Guihua forest farm was investigated by using three structure parameters （mingling, neighborhood comparison, and uniform angle index -- neighboring tree distribution pattern）. The results showed that Castanopsis sclerophylla was the dominant spe- cies in mixed forest, which exhibited aggregation of single species, and the rest tree species were more or most intensive in mingling. When using neighborhood comparison method to characterize the size differentiation of trees,Liquidambarformosana Hance had an advantage over other species which differentiated seriously both in dominant species and suppressed species. Considering tree distribution pattern using uniform angle index, the stands in this community was found to be a clumped distribution.
