本文从林分结构、生物量、群落特征、生产力、培肥土壤、涵养水源及林内小气候等方面对不同混交模式的杉木拟赤杨混交林及其纯林进行的研究结果表明:杉木拟赤杨是具有较高生产力和协调种间关系能力的针阔混交树种。7年生31带状混交林蓄积量和生物量分别比杉木纯林提高7.24%和18.22%,同时混交林还表现出比杉木纯林更好的培肥土壤、涵养水源、改善林内小气候等生态功能。应用AHP法进行不同混交模式的综合选择结果表明:31杉木拟赤杨带状混交模式是值得南方林区大力推广的杉阔混交模式。
In this paper, the research on the mixed forest of Alnus cremastogyne and Cunninghamia lanceolata with different mixed modes from the aspects of stand structure, biomass, community characteristics, productivity, soil fertility, water conservation and microclimate in forest showed that: It is a coniferous and broad-leaved mixed tree with higher productivity and ability to coordinate interspecific relationships. The volume and biomass of the 7-year-old mixed forest in 31 years increased by 7.24% and 18.22%, respectively, compared with pure Chinese fir plantation, while the mixed forest also showed better soil fertility than the pure Chinese fir plantation, Microclimate and other ecological functions. The results of comprehensive selection of different mixed mode by AHP show that the mixed model of Fir (Cunninghamia lanceolata) Cunninghamia lanceolata is worthy of the mode of Chinese fir and broad-leaf mixed vigorously promoted in the southern forest region.
