摘要：基于野外实测数据和碳税法对若尔盖高原泥炭地的固碳价值进行了定量评价。结果表明:若尔盖高原泥炭地总体表现为CO_2的汇和CH_4的源,年净固定CO_2的量为2 922 kg CO_2/hm^2,年CH_4排放量约为48 kg CH_4/hm^2,换算成CO_2当量约为1 163 kg CO_2/hm^2。若尔盖高原泥炭地总CO_2的排放量为23 375.6 kg CO_2/hm^2,其中CH_4排放的CO_2当量仅占到了总CO_2排放的5%。将若尔盖高原泥炭地吸收CO_2的正效应减去CH_4排放的负效应,得到若尔盖高原泥炭地的年净固碳量为1759.4 kg CO_2/hm^2,总体表现出较强的碳汇功能。若尔盖高原泥炭地净吸收CO_2的价值为11.50亿元(正效应价值),净排放CH_4的价值为4.58亿元(负效应价值)。将正负效应进行整合,得到整个若尔盖高原泥炭地的总固碳价值为6.92亿元。
Based on field data and carbon tax method,the value of carbon sequestration of Zoige alpine peatland was quantitatively evaluated.The results showed that the targeted alpine peatland was a CO2 sink and CH4 source.The net annul sequestration of carbon dioxide(CO2)of Zoige alpine peatland was 2 922 kg CO2/hm2,and the annual CH4 emission was about 48 kg CH4/hm2,equivalent to about 1 163 kg CO2/hm2 in terms of CO2 equivalent.The total CO2 emissions from the Zoige alpine peatlands were 23 375.6 kg CO2/hm2,where the CO2 equivalent of CH4 emissions accounted for only 5%of the total CO2 emissions.Subtracting the negative effect of CH4 emission,the net carbon fixation capacity of the Zoige alpine peatland is 1 759.4 kg CO2/hm2,showing a strong carbon sink.The values of net CO2 uptake(positive value)and CH4 emission(negative value)were 11.50 and 4.58 billion yuan,respectively.Combing the positive and negative value,the total value of carbon sequestration in Zoige alpine peatland was 6.92 billion yuan.
