摘　　要：通过秃杉与光皮桦2∶1和4∶1比例及秃杉与杉木1∶1比例行状混交,与营造秃杉纯林进行造林效果对比,结果表明:不同类型林分中秃杉生长量顺序为秃杉+光皮桦2∶1混交林>秃杉+光皮桦4∶1混交林>秃杉+杉木1∶1混交林>秃杉纯林;混交林土壤>0.25 mm的团聚体含量、有机质含量、速效磷含量和速效钾含量等高于纯林,而混交林土壤结构体破坏率低于纯林。秃杉与光皮桦2∶1的比例行状混交的效果最佳。This study compared the mixed effect of 2∶1 and 4∶1 of Taiwania cryptomerioides and Betula luminifera and 1∶1 of Taiwania cryptomerioides and Cunninghamia lanceolata with the effect of Taiwania cryptomerioides afforestation.The results showed that the order of the growth in the different types of stands was mixed forests of 2∶1 of Taiwania cryptomerioides and Betula luminifera,4∶1 of Taiwania cryptomerioides and Betula luminifera,1∶1 of Taiwania cryptomerioides and Cunninghamia lanceolata,pure forests of Taiwania cryptomerioides from more to less.Aggregate content,organic matter content,quick phosphorus content and quick potassium content of the mixed forest soil more than 0.25 mm were higher than pure forests,while the destruction rate of mixed forest soil structure was lower than that of pure forests.The mixed effect of 2∶1 of Taiwania cryptomerioides and Betula luminifera was the best.
