| 摘 要： | 采用祁连山国家公园青海片区2017年的林地变更数据,乔木林和疏林地采用IPCC法,灌木林采用缺省值法,研究了祁连山国家公园青海片区森林植被的生物量、碳储量和碳汇价值。结果表明:(1)祁连山国家公园青海片区森林植被总生物量为339.71万t,总碳储量为170.23万t,单位面积生物量为19.73 t·hm-2,碳密度为9.89 t·hm-2,碳交易的潜在价值为2723.61万美元(JI)或4119.46万美元(CDM);(2)乔木林不同树种组的生物量总量、碳储量总量大小排序一致,均为青海云杉Picea crassifolia>祁连圆柏Sabina przewalskii>糙皮桦Betula utilis>白桦B.platyphylla>红桦B.albosinensis>杨树Populus spp.(山杨P.davidiana、青杨P.cathayana、其它杨树)。(3)乔木林不同树种组单位面积生物量和碳密度大小排序一致,均为青海云杉>红桦>白桦>糙皮桦>祁连圆柏>杨树。(4)片区内乔木林总生物量和碳储量中,幼、中龄林所占比例最大(分别为66.2%和66.1%),其原因是近些年青海省依托祁连山环境治理,在祁连山国家公园范围内加大了造林力度,使幼龄林和中龄林比例不断增加。

| Abstract: | Based on the data of forest land in Qinghai area of Qilian Mountain National Park in 2017,forest biomass,carbon reserve and sequestration were studied by IPCC and default value method.The results showed that the total biomass and total carbon reserve of forest was 3.3971 million ton and 1.7023 million ton,respectively.Unit area biomass was 19.73 t/ha,and the carbon density was 9.89 t/ha.The potential value of carbon trading reached to 27.2361 million US$(JI)or 41.1946 million US$(CDM).Total biomass and reserve of different arbor species was ordered by Picea crassifolia>Sabina przewalskii>Betula utilis>B.platyphylla>B.albosinensis>Populus spp.(P.davidiana,P.cathay,etc.).Unit area total biomass carbon density of different arbor tree species was ranked by P.crassifolia>B.albosinensis>B.platyphylla>B.utilis>S.przewalskii>Populus spp..Young and middle-aged forests occupied 66.2%and 66.1%of the total biomass and carbon reserve,which increased quickly in Qilian Mountains National Park in recent years.It was the result of afforestation. |
