Analysis of the CO2 Emission Performance of Urban Areas in Yangtze River Delta Region
摘要
Abstract
The CO2 emission performance of urban areas in Yangtze River Delta region are analyzed based on 1 km gridded CO2 emission data which is built bottom-up by point emission sources and urban boundaries defined by the Fifth National Population Census. The spatial feature of CO2 emissions in Yangtze River Delta region were driven and affected by certain key urban areas. Shanghai is the emission center of this Delta region, and its urban area boundary and emission structure are basically consistent with Shanghai administrative region. The direct emissions of urban areas in Jiangsu and Zhejiang provinces accounted for 47. 05% and 36. 96% of the direct emissions of their respective provinces. The per capita emissions of urban areas in these two provinces were lower than rural and regional level of their provinces respectively. The emission comparison results are consistent with what have been found in the developed countries, and indicated that the emission performance in urban areas will be better than that in non-urban areas when urban and economic condition are well developed. There were emerged double emission centers in some prefecture-level regions ( e. g. , Suzhou region and Ningbo region), while some urban areas (e. g. , Shanghai and Kunshan, Wuxi and Zhangjiagang) belonging to different prefecture-level regions have merged together. The growth rate of CO2 emission were quicker than the growth rate of population in the urban areas of the Yangtze River Delta region, where a 1% increase in population size is associated with a nearly proportional increase in CO2 emission of 1. 35%. This generally implies that the CO2 emission performance will degrade with the size of urban area increase. The main reason is the high variations of population size and development level of urban areas. The per capita emissions varied widely among urban areas when their population size is lower than 1 million, and keep stable and below 10. 00 t/person when population size is larger than 1 million.关键词
