摘要
基于常规可获取的能源、交通、人口等统计资料,利用"自上而下"的能源清单法,研究了2010年长江三角洲(以下简称"长三角")城市群地区各类人为热排放量及其时空分布特征.结果表明:该地区人为热排放总量为1.4×1019J/a,其中工业、交通、建筑、新陈代谢分别占75.1%、12.5%、9.9%和2.5%.上海、苏州、无锡、杭州和南京五个城市的人为热排放总量约占研究区域总量的71%.长三角城市群的人为热年平均排放通量为5.3W/m2,大部分地区介于5~30W/m2,城市高值区一般介于20~70W/m2,上海明显高于其他城市.为方便有关环境气候模式的输入,本文提供了人为热排放的网格化空间分布和简单的时间变化廓线.
