摘要
Based on the 1973 - 2003 temperature data of Guangzhou meteorological station and 1980 - 2000 temperature data of Foshan airport, the variations of urbanization effect on temperature of Pearl River Delta （PRD） and Guangzhou city were analyzed. It was found that the temperature has increased significantly due to the PRD＇s urbanization. During the last 20 years, Foshan airport＇s temperature has increased by 0.7℃, and the Guangzhou city＇s temperature increased by about 1.℃ during last 30 years. The heat island of Guangzhou city is obvious but has some differences from other big Chinese cities.
