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。
The harvesting method was used to calculate the biomass of nine newly-established stands after the revamping of Baiyun Mountain in Guangzhou. Based on this, the photosynthetic carbon fixation and oxygen release values of these stands were evaluated. The total value of photosynthetic carbon sequestration and oxygen release of various forest stands were: Schiphol 851 477.17 USD / hm2, Lithocarpus 244 597.27 USD / hm2, Sauvignon Eucalyptus 603 695.00 USD / hm2, Acacia 372 768.99 USD / hm2 , Chenopodiaceae 289 537.77USD / hm2, Sinocape 437 500.48 USD / hm2, reduced real Xiang 109 758.10 USD / hm2, sharp leaves Du Ying 146 324.94 USD / hm2, Caribbean pine 138 039.68 USD / hm2. With Schima superba and Acacia photosynthetic carbon and oxygen highest value.
