摘　　要：本文从林分生长、空间分布格局、生物量及其与生态环境的相互作用等方面对14年生福建柏、杉木纯林及其混交林作了对比研究。结果表明,在南方丘陵营造福建柏、杉木混交林有利于维护地力和形成稳定的人工林生态系统,在经济、生态和美学方面均优于杉木纯林。混交林生物量比杉木、福建柏纯林高22.9％和4.7％,达79.58 t/ha,福建柏纯林比杉木纯林高17.4％。补植福建柏是改造杉木中低产林的有效措施之一。Successive cultivation of Chinese fir (Cunninghamia lanceolata) monoculture has resulted in site degradation, productivity decrease and widespread of diseases and pest in South China. Thus in 1977, we introduced a dozen of tree species to Zhuting, Hunan Province, in order to select the appropriate species for planting. This report is based on the research results from a part of the project. Data on growth, structure, biomass and ecological parameters of three stands were collected in 1989 and 1990. The results showed that Chinese fir interplanted with Fokienia hodginsii, (Fukien cypress) on poor sites helps maintain soil fertility and site productivity in long-term, promote its growth and establish a stable, man-made forest ecosystem, The total biomass of a 14-year-old mixed stand is 79.58t/ha, 22.9 percent higher than that of pure stand of Chinese fir. In the view of economics, ecology and aesthetics, the mixed stands have several advantages over the pure stands of either Chinese fir or of Fukien cypress.
