| 摘要: |
| 利用广州气象站近30年气温资料和受城市发展影响相对较小的佛山沙堤机场20年气温资料,分析珠江三角洲地区的温度变化趋势及广州城市发展对温度场的影响程度。结果表明,珠江三角洲地区温度上升趋势明显,佛山沙堤机场20年上升0.7℃,广州30年上升约1.1℃。广州市热岛效应具有明显的年、季节及日变化规律,与国内其它城市热岛变化规律有所不同。 |

| Abstract: |
| 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 1.1℃ during last 30 years.The heat island of Guangzhou city is obvious but has some differences from other big Chinese cities. |
