本文利用相对生长法和样方收获法分剐调查了广西不同生态地理区域杉木近熟林中乔木层、灌木层、草本层和枯枝落叶层的生物量。根据调查数据,建立了不同区域估测乔木层单株林木各器官生物量的回归方程。研究结果表明,不同生态区域,杉木森林群落的生物量和生产力是宜山甘村>龙胜里骆>田林利周>岑溪七坪。生物量在群落中的分配是乔木层>枯枝落叶层>草本层>灌木层。广西东部、中部和西部,存在着发展杉木的生产潜力,宜作为培养中径用材林基地。
In this paper, relative growth method and quadrat harvesting method were used to investigate the biomass of arborous layer, shrub layer, herb layer and litter layer in nearly mature forest of Cunninghamia lanceolata in different ecological geographical regions of Guangxi. According to the survey data, the regression equations for estimating the biomass of individual organs of tree stand in different regions were established. The results showed that the biomass and productivity of Chinese fir community in different ecological regions were Yishan Gancun> Longshenglioluo> Tianlinlizhou> Cenxiqianping. Biomass distribution in the community is the arbor layer> litter layer> herb layer> shrub layer. Guangxi eastern, central and western, there is the potential for the development of Chinese fir production, should be used as training base for the timber forest.
