| 摘 要： | 杉木球果瘿蚊虫果空间分布经３类分析方法检验均显示为聚集；杉木树冠部位对虫果率无显著影响，虫果率调查抽样方式以平行线抽样较适合；抽样数据的统计代换可采用对数代换［Ｘ＇＝Ｉｎ（Ｘ＋１）］或Ｔａｙｌｏｒ的方法（Ｘ＇＝Ｘ－０．２５８５）。

| Abstract: | Analysis with 3 different methods on spatial distribution of cone of Cunninghamia lanceolata infected by gau midge(Cecidomyidae sp.) demonstrated aggregative;crown of Cunninghamia,lanceolata had no evident effect on diseased strobile rate;sampling of diseased strobile rate with parallel lines method was relative better;statistical conversion could adapt logarithmic X'=In(x 1)] or Taylor method (X'=X-0.2585). |
