摘　　要：采用收获法计算了广州白云山林分改造后9种新建林分的生物量,并在此基础上评估了这些林分的光合固碳和放氧价值。各种林分的光合固碳和放氧的总价值分别为:木荷851 477.17 USD/hm2,石栎244 597.27 USD/hm2,大叶相思603 695.00 USD/hm2,马占相思372 768.99 USD/hm2,藜蒴289 537.77USD/hm2,中华锥437 500.48 USD/hm2,降真香109 758.10 USD/hm2,尖叶杜英146 324.94 USD/hm2,加勒比松138 039.68 USD/hm2。以木荷和大叶相思的光合固碳和放氧价值最高。Biomass of 9 newly established forest stands in Baiyunshan Scenic Spot, Guangzhou, was gauged using harvest method, followed by the valuation of the photosynthetic carbon sequestration and oxygen production by each stand. The total value of carbon sequestration and oxygen production of each stand are as follows Schima su- perba 851 477.17 USD/hm2, Lithocarpus glaber 244 597.27 USD/hm^2, Acacia auriculaeformis 603 695. 00 USD/ hm^2, Acacia mangium 372 768.99 USD/hm^2, Castanopsis fissa 289 537.77 USD/hm^2, Castanopsis chinensis 437 500.48 USD/hm^2, Acronychia pedunculata 109 758.10 USD/hm^2, Elaeocarpus apiculatus 146 324.94 USD/hm^2 and Pinus caribaea 138 039.68 USD/hm^2. Among each stand , the total value of carbon sequestration and oxygen production , Schima superba is the highest, and Acacia auriculaeformis comes out the second
