摘　　要：文章采用2001-2010年常规气象站资料,主要来自沈阳城区与郊区(法库、新民、康平、辽中)一日4次温度记录,分别为02、08、14、20时。分析结果:热岛强度10年间呈V字型变化,但是2005年后的几年还是比前几年高一些;1、2月份热岛有下降趋势,3月份有上升;4月份热岛强度变化不大,5月份热岛有上升趋势,6月份热岛后5年比前5年高;7月份热岛有升高趋势,2001年最低,2010年最高,8月份后5年比前5年有增加趋势,除了2005年和2004年,8月份在10年中热岛强度比较强,9月份前5年热岛强度较后5年高,热岛强度有下降趋势;10月份热岛强度月平均值最高和最低两年相差很大,前5年热岛强度平均值和后5年平均值差不多;11月份后5年热岛强度比前5年热岛强度高,热到强度成逐渐增加趋势,12月份后5年比前5年热岛强度高,有增加的趋势。然后用MM5模式模拟10年中强热岛日—2007年12月25日的风场、温度场,结果显示温度场模拟结果和观测结果基本一致;风场越稳定,热岛强度越强;越不稳定,热岛强度越弱。Based on the 2001-2010 conventional meteorological station material mainly from shenyang urban area and suburbs(Faku、Xinmin、Kangping、Liaozhong) a day four temperature records,respectively 02 、08、14 、20.The analysis results: heat island intensity 10 years into V font changes,but after 2005 years or more than a few years ago have some high;In January and February heat island have to decline,March have rise;April heat island intensity change is not big,may heat island had a tendency to rise,June heat island after five years than the previous 5 years high;July heat island have rise trend,2001 minimum,in 2010 the supreme,August 5 years after the previous five years has increasing trend,except in 2005 and 2004,visible August in 10 years heat island intensity is stronger,September 5 years before heat island intensity is high after five years,heat island intensity have to decline;In October,heat island intensity month average maximum and minimum two years vary considerably and the first five years of heat island intensity average and after five years average almost;November 5 years after heat island intensity than the first five years of heat island intensity is high,the heat to strength into gradually increasing trend,December after five years than the first five years of heat island intensity is high,has a trend of increase.Then use MM5 model simulation 10 years strong heat island,December 25,2007 wind field temperature field,results: the simulation results and the observation results are basically the same,Wind field is more stable heat island intensity are stronger,more unstable heat island intensity weaker.
