摘　　要：基于气温数据,对1961—2008年沈阳近郊和远郊热岛强度的月、年和年代际动态变化及其与城市化的关系进行研究.结果表明:沈阳近郊的月热岛强度和年热岛强度均高于远郊,即从近郊到远郊,热岛强度呈减小趋势.近郊和远郊热岛强度的变化趋势在3—11月较为一致,12月至翌年2月相反,这可能与冬季取暖有关.近郊和远郊的年热岛强度在2000年前呈上升趋势,2000年后呈下降趋势.年热岛强度与城市绿地面积、人口数量和建成区面积在2000年前呈显著的正相关(P<0.05),2000年后呈显著的负相关(P<0.05);三者与年热岛强度的关联度分别为0.43、0.52和0.26.The monthly,annual,and inter-decade variations of heat island effect in inner and outer suburbs of Shenyang and their relationships with urbanization were analyzed,based on the air temperature data from 1961 to 2008. It was indicated that the monthly and annual heat island effect was higher in inner suburb than in outer suburb,and decreased from inner suburb to outer suburb. The variation trend of monthly heat island effect in inner and outer suburbs was similar from March to November,but in contrary from December to next February,possibly due to the effects of heating in winter. The annual heat island effect in both inner and outer suburbs had an increasing trend before 2000 but a decreasing trend after 2000,and was significantly positively correlated with the green land area,population,and established construction area before 2000 （P0.05）,but significantly negatively correlated with them after 2000 （P0.05）,the correlation degree being 0.43,0.52,and 0.26,respectively.
