摘　　要：以邓恩桉(Eucalyptus dunnii)和杉木(Cunninghamia lanceolata)为混交树种,对不同混交模式下邓恩桉与杉木的林木生长情况进行分析。研究表明:混交模式下,邓恩桉的树高、胸径生长量明显高于纯林,其中以7∶3 (杉木∶邓恩桉)的配置模式效果最好;混交模式杉木的胸径生长量也明显高于纯林。Growth situation of Eucalyptus dunnii and Cunninghamia lanceolata in different mixed patterns was analyzed by using E. dunnii and C. lanceolataas as mixed tree species. Results showed that tree height and diameter at breast height （DBH） of E. dunnii were obviously higher than those of pure forest in the mixed modes, and the ratio of 7 ： 3 （C. lanceolata ： E.dunnii） in the pattern was the best; the increment of DBH of C. lanceolata in the mixed modes was obviously higher than that of pure forest.
