摘要 在杉木纯林采伐迹地上分别营造杉木、马尾松、木荷纯林以及杉木×马尾松、杉木×木荷、杉木×马尾松×木荷的混交林,造林后16 a对比分析不同类型林分的生长量、生物量以及土壤理化性质等。结果表明,杉木×马尾松×木荷混交林在林木生长量、生物量、改良地力等方面均明显优于其它类型林分。3树种混交林林分结构合理,可在一定程度上改善林内生长环境和土壤质量,提高土壤肥力,促进林木生长,其林分蓄积量,比纯林提高45.13%-127.03%,比2树种的混交林分提高15.27%-30.63%。 Three types of mixed forest and three types of pure forest with Cunninghamia lanceglata, Pinus massoniana and Schima superba were afforested in the foresfland of C.lanceolta clear-cutted. The growth effect, stand biomass and soil chemical and physical properties of different forest stands were analyzed after 16 years afforestation. The results showed that the mixed forest with C.lanceolata, P. massoniana and S. superba is much better than other types in growth, stand biomass, stand structure and soil improvement. The stand structure of the mixed forest with the 3 tree species was reasonable and helpful to improve the inner environment, soil quality and fertility which promoted the forest growth. The stand volume of mixed forest with 3 species was higher than pure forest and mixed forest with 2 species, reached to 45.13% - 127.03% and 15.27% -30.63% respectively.
