摘　　要：在马尾松1 a生纯林内补植福建柏、台湾相思,分别形成2树种和3树种的混交林。造林14 a后,对比分析各林分的林木生长量、林分生物量以及林分土壤理化性质。结果表明:马尾松、福建柏、台湾相思3树种的混交林,林分结构合理,林木生长较快,枯枝落叶物多,明显改善了土壤的理化性质及林分内的小环境。3树种混交林比马尾松纯林和2树种异龄混交林的林木蓄积量分别提高12.91%和6.06%、26.88%。Fokienia hodginsii and Acacia confusa were planted in 1-year-old pure Masson＇s pine （Pinus massoniana） plantation which developed into different mixed forests with two species or three species. Comparative analysis on the growth increment, stand biomass and soil physi-chemical properties of different forest stands were carried out after 14 years. The results show that the mixed forest with three species was reasonable stand structure with improved soil properties and better forest inner environment, which had faster forest growth and more forest litter by compared with the mixed forests with two species and pure masson＇s pine forest. The stand volume of mixed forest with three species was higher than pure masson＇s pine forest and mixed forest with two species （R massoniana and E hodginsii, P. massoniana and A. confusa）, accounting for 12.91%, 6.06% and 26.88%,respectively.
