Using the monthly mean air temperature data and statistical data in urban and suburb of Anshan from 1958 to 2012,the urban heating island (UHI)effect and the impact of urban development on UHI were analyzed by methods of a trend analysis,a grey correlation degree and a correlation analysis.The results show that the monthly UHI intensity fluctuates between 0.72-1.39 ℃.The maximum and minimum values appear in December and August,respectively.There is an increasing trend for UHI in Anshan,and its increasing trend is 0.19 ℃ per decade.Annual UHI is a positive relation with annual mean low cloud cover and annual mean air temperature in Anshan,while it is a negative relation with annual average wind speed,annual average relative humidity and sun-shine percentage.Annual mean UHI has a quadric curve relation with urban population,built-up area,green land area and gross industrial output value.The order of correlation degree between UHI and meteorological factors in Anshan is:annual average air temperature >sunshine percentage >annual average relative humidity >annual aver-age total cloud cover.On the other hand,the order of correlation degree between UHI and urbanization indexes is:urban population >built-up area >green land area >gross industrial output value.%利用1958—2012年鞍山市区、郊区的月平均气温资料及鞍山市统计资料，采用趋势分析、灰色关联度和相关分析等方法，探讨了鞍山地区的城市热岛效应和城市发展对热岛效应的影响。结果表明：鞍山地区月热岛强度呈波动分布，月平均热岛强度为0．72—1．39℃之间；最大热岛强度出现在12月，最小热岛强度出现在8月。1958—2012年鞍山地区热岛强度呈上升的趋势，增加趋势为0．19℃／10 a。鞍山地区年热岛强度与年平均低云量和年平均气温呈明显的正相关，与年平均风速、年平均相对湿度和年日照百分率呈负相关。年平均热岛强度与城市人口数量、建成区面积、绿地面积和工业生产总值均呈二次曲线关系。鞍山地区年热岛强度与气象因子的关联序为：年平均气温＞年日照百分率＞年平均相对湿度＞年平均总云量，年热岛强度与城市化指标的关联序为：人口数量＞建成区面积＞绿地面积＞工业生产总值。
