摘要: 构建上海1 km CO2排放网格,分析市域(UB1)、市辖区(UB2)、建成区(UB3)和城区(UB4)4个城市范围的CO2排放特征。上海市域CO2排放空间格局是以中心城区为核心,排放水平向外递减,形成了3个梯度。空间自相关分析表明,排放在空间上存在显著的集聚效应,部分地区高强度的经济活动和能源活动对周边区域的排放有显著影响。UB4是上海城市的最佳表征,2007年UB4内CO2排放达到1.89亿t,人均排放12.04 t;UB4排放占UB1排放的75.40%,UB1人均排放比UB4人均排放高12%。上海城市化和工业化在空间上的高度重合,导致高排放源集聚于UB4内,形成UB4的高排放特征。个别网格的排放量已经占到区域或者城市总排放量的10%~20%;前10高和前100高排放网格,其累积排放总量分别占据了3个城市范围(UB1、UB3和UB4)总排放量的60%和80%以上。

Abstract: Based on the 1 km CO2 emission gridded dataset, the CO2 emissions of Shanghai’s four urban boundaries, namely city administrative boundary (UB1), city district boundary (UB2), city built-up area (UB3) and urban proper (UB4) respectively, were analyzed and compared. The spatial characteristics of CO2 emissions of UB1 showed three gradient distribution patterns with city center as the hotspot and emissions of grids gradually decreasing outward. There was spatially clustering phenomenon in CO2 emissions in UB1, and emissions of some local areas may have significant positive effect on its surrounding area, which indicated by spatial autocorrelation analysis. The UB4 is the appropriate boundary for city of Shanghai. The CO2 emissions in UB4 totaled to 189 million t, and per capita emissions reached 12.04 t in 2007. The emissions of UB4 accounted for 75.40% of the emissions of UB1. The per capita emissions of UB1 were 12% higher than that of UB4. The industrial area and urban area were spatially coincided in a high degree in Shanghai, which led to high emission sources concentrated in UB4. Emissions of top one grid accounted roughly for 10%-20% of total emissions in 3 correspondent urban boundaries. The emission sum of top 10 and top 100 grids accounted for more than 60% and 80% respectively, of the total emissions in 3 correspondent urban boundaries.

Key words: Shanghai, urban boundaries, CO2 emissions
