通过测定长春市6种常见绿化植物净光合速率及绿量,计算出其固碳释氧能力,并运用碳税法及工业制氧成本法计算此6种树木日固碳释氧价值。结果表明:所选6种植物中,京桃(Prunus persica f.rubro-plena)、银中杨(Poplusalba’Berolinensis’L.)固碳释氧能力最强,其日固碳释氧价值最高,火炬树(Rhus typhina Nutt)、杏(Prunus armeniaca)、樟子松(Pinus sylvestris var.mongolicaLitv.)、旱柳(Salixmatsudana)固碳释氧能力较弱,日固碳释氧价值最低。
The net photosynthetic rate and the amount of green photosynthesis of six common green plants in Changchun were calculated, and their carbon sequestration and oxygen release capacities were calculated. The carbon sequestration and oxygen release values of these six trees were calculated by the carbon tax method and the industrial oxygen production cost method. The results showed that Prunus persica f. Rubro-plena and Poplus alba’Berolinensis’L. Had the highest ability of carbon fixation and oxygen release, the highest values of carbon fixation and oxygen release, Rhus typhina Nutt, Prunus armeniaca, Pinus sylvestris var. Mongolica Litv. And Salix matsudana were weak in carbon sequestration and releasing oxygen, and had the lowest values of carbon fixation and oxygen release.
