为探寻不同区域城市热岛效应对降雨量的影响，以地处中国东部沿海地区的徐州市为例，通过收集城区及周边多处雨量站29 a 雨量观测资料，计算并比较城区内、外平均降雨量的差异，得出热岛效应引起的雨量增加值为9.95%，产生的主要原因为区域自然下垫面变化、城区面积的增大和人类活动。

To explore the urban heat island effect on rainfall of different regions, this article takes Xuzhou which locates in the eastern coastal areas of China as an example. Based on the rainfall data on the urban area and surrounding areas captured by several rainfall stations in 29 years, the difference of the average rainfall between inner-city and outside city is calculated and compared. The added value of rainfall which is caused by heat island effect is 9.95%. The main reasons are changes of regional natural underlying surface, the enlargement of urban area and human activity.
