中文摘要:

从防卫气象学的卫星程序(DMSP )/Operational Linescan 系统(OLS ) 卫星的稳定的轻数据和中国的统计的国家的局散布的权威的精力消费数据被用于从 1992 ~ 2009 在中国估计人为的热版本的分发。一种强壮的线性关系在 DMSP/OLS 数字数字数据和人为的热流动密度(AHFD ) 之间被发现。结果显示在中国的那个人为的热版本地理上被集中并且根本上与经济活动被相关。在在北、东方、南部的中国的经济地发达的区域的人为的热版本比另外的区域大得多,而它在西北、西南的中国是很小的。在中国的吝啬的 AHFD 在 2008 在 1978 ~ 0.28 W m2 从 0.07 W m2 增加了。结果在北京,长江三角洲,和珀尔河三角洲的人为的集中热的区域显示那, AHFD 层次比一般水准高得多。在气候变化上加重人为的热版本的效果值得进一步的调查。

英文摘要:

Stable light data from Defense Meteorological Satellite Program (DMSP)/Operational Linescan System (OLS) satellites and authoritative energy consumption data distributed by National Bureau of Statistics of China were applied to estimating the distribution of anthropogenic heat release in China from 1992 to 2009. A strong linear relationship was found between DMSP/OLS digital number data and anthropogenic heat flux density (AHFD). The results indicate that anthropogenic heat release in China was geographically concentrated and was fundamentally correlated with economic activities. The anthropogenic heat release in economically developed areas in northern, eastern, and southern China was much larger than other regions, whereas it was very small in northwestern and southwestern China. The mean AHFD in China increased from 0.07 W m-2 in 1978 to 0.28 W m-2 in 2008. The results indicate that in the anthropogenic heat- concentrated regions of Beijing, the Yangtze River Delta, and the Pearl River Delta, the AHFD levels were much higher than the average. The effect of aggravating anthropogenic heat release on climate change deserves further investigation.
