长春市6种绿化树种固碳释氧价值核算

Valuation of Photosynthetic Carbon Sequestration and Oxygen Production of the 6 tree species in Changchun city,China

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。

Net photosynthetic rate and greenmT quantity of the 6 tree species in Changehun city, China,was determined,and take this as the loundatlon, caleulated the ability of photosynthetic carbon sequestration and oxygen production of the 6 tree species,followed by the valuation of photosynthetic carbon sequestratiou and oxygen production of the 6 tree species,using the Carbon ＇Fax and Industrial oxygen generation cost metbod.The result showed：lhe wduation of photosynthetie ~arbon sequestration and oxygen production of each tree specie are as tollow Prunus persica f. rubro-plena γ198.00, Poplus alba ＂Bemlinensis L. γ199.20, Prunus armeniaca γ127.80, Pinus sylvestris var. mongolicaLitv g115.40, .Rhus typhina Nutt γ67.52, Salixmatsudana γ13.50. Among each species, Pmnus persiea f. ruhro-plena and Poplus alba ＂Berolinensis. L. was highest, and the others are lower.
