【摘要】：為了更好地了解城市的碳氧平衡狀況,利用NDVI數(shù)據(jù)、能源消費(fèi)數(shù)據(jù),基于NPP模型,碳排放與氧消耗估算模型以及箱式模型計(jì)算北京市及各區(qū)的碳氧收支狀況。結(jié)果表明:(1)研究區(qū)11年平均固碳釋氧量由城市中心區(qū)向外圍逐漸降低;(2)碳排放量與氧消耗量2010年較2000年增加幅度較大,碳排放量11年增加了2284.1161×104 t;氧消耗量增加了4334.59×104 t。2010年各區(qū)碳排放量與氧消耗量所占比重差別較大,城市拓展區(qū)與發(fā)展區(qū)分別占到總量的41.67%、40.27%;城市中心區(qū)與涵養(yǎng)區(qū)比重較小分別為10.19%、7.87%。(3)從研究區(qū)年碳氧收支狀況來看,2010年碳氧失衡較2000年嚴(yán)重;分區(qū)來看,城市拓展區(qū)在總量與單位面積上失衡最嚴(yán)重,涵養(yǎng)區(qū)失衡最弱;其他區(qū)域在總量與單位面積失衡方面有一定差別。
[Abstract]:In order to better understand the carbon and oxygen balance of cities, using NDVI data, energy consumption data, based on NPP model, The carbon emission and oxygen consumption estimation model and the box model were used to calculate the carbon and oxygen budget in Beijing and various districts. The results showed that the average carbon sequestration and oxygen release in the study area decreased gradually from the central area to the periphery of the city. The increase in consumption in 2010 was greater than that in 2000, Carbon emissions increased by 2284.1161 脳 104t in 11 years, and oxygen consumption increased by 4334.59 脳 104t.2010. The proportion of urban development area and development area is 41.67 and 40.27, respectively; the proportion of urban center area and conserved area is 10.197.87.3.According to the annual carbon and oxygen budget in the study area, the carbon-oxygen imbalance in 2010 is more serious than that in 2000. The imbalance between the total amount and the unit area is the most serious in the urban development area, and the imbalance between the total amount and the unit area is the weakest in the conservation area, while there are certain differences between the total amount and the unit area imbalance in the other regions.
