摘 要: 采用生态学理论与方法分析广州市"万亩果园"的群落特征,介绍了估算固碳制氧量的生物量法,估算出了果园果树的生物量为54 353.7 t,固定CO2的量为88 596.531 t,释放的O2为65 224.44 t,年单位面积固碳量为3.2 t/hm2,年单位面积制氧量为2.38 t/hm2。果园的固碳制氧的经济价值为21 873.02元/hm2。 In this paper, the author adopts the sample survey method to estimate that the biomass of all fruit trees is 54 353.7t, the total quantity of the fixed CO2 is 88596.531t by orchard community in Guangzhou "ten thousand acres orchards", the total quantity of the produced oxygen is 6 5224.44 t, annual carbon fixation yield of per unit area is 3.2 t/hm^2, annual yield of oxygen production is 2.38 t/hm^2, and its economic value is 21 873.02 yuan/hm^2.
