摘要/Abstract

摘要： 根据中国统计年鉴中各地区能源消费资料和人口数据，研究了长三角城市群的人为热排放，对其进行了时间和空间上的分析，讨论了长三角地区的人为热分布特点及影响因素。结果表明，长三角地区的人为热释放量是随时间持续增长的，上海地区的年均人为热通量从1990年的5.47W/m2到2010年增加为14.46 W/m2，江苏和浙江也分别从0.68、0.33 W/m2增加到2.61、1.63W/m2；人为热释放空间分布不均匀，总体上来说还是以城区为高值中心，向郊区逐渐减小，这种分布与人口密度、工业和经济发展程度密切相关。此外，长三角整个区域的人为热通量都高出全国平均值一个量级以上，而且高值区域已经初步连成一片，人为热将对区域气候造成一定影响。从1990年到2000年，长三角16个城市的城区的人为热通量都是稳步增长的；2000年后人为热通量开始快速增长，增长速度最高可达2W/m2/yr。城市人为热排放愈来愈强，对城市局地小气候和空气污染影响将越来越重要。

Abstract: Based on the energy consumption data and demographic data of Yangtze River Delta region (YRD), the temporal and spatial variation of anthropogenic heat flux (AHF) in YRD was estimated. The characteristics and the influence factors were discussed. The results show that AHF over YRD has been growing from 1990 to 2010. The annual mean values of Shanghai, Jiangsu and Zhejiang have increased from 5.47, 0.68, 0.33 W/m2 to 14.46, 2.61, 1.63 W/m2 respectively in two decades. The spatial distribution of AHF, which is related to the population density, the industrial level and economic development, is uneven. The value in YRD is one order of magnitude larger than that for the national average. The value in the urban center is higher than that in the surrounding areas. From 1990 to 2000, the AHF of the 16 core cities in YRD grew steadily. However, the growth accelerated after 2000, and the maximum rate can get to 2 W/m2 a year. The stronger the AHF is, the more important the effects of AHF on local microclimate and air pollution will be
