| 摘 要： | 利用2011～2017年遂宁市主城区气温观测资料、MODIS卫星遥感资料,Landsat TM影像资料,结合遂宁市海绵城市建设,对遂宁市主城区城市热岛效应进行评估,得到以下结论:气象观测资料显示遂宁市主城区存在城市热岛效应,且从2011～2016年,其热岛效应总体呈下降趋势;遂宁主城区夏季热岛强度最强,春季次之。基于MODIS卫星资料分析得到:2011～2014年,遂宁主城区的城市热岛范围逐渐扩大;强热岛和极强热岛主要集中市中心,2016年到2017年,城市热岛出现了一定的缓解,强热岛和极强热岛被消除。2017年极端高温下的遂宁市主城区城市热岛效应比2006年的弱。海绵城市建设增加了遂宁市主城区绿地面积、水域面积、改变了城市路面、合理规划了城市建设,使遂宁市主城区热岛效应得到了一定的缓解。

| Abstract: | By using the observational data of temperature in Suining main urban area during 2011 ~ 2017, the MODIS satellite remote sensing data and the Landsat TM image data, combine with sponge city construction of Suining city, the urban heat island effect of Suining city was evaluated. The meteorological observation data showed that the urban heat island effect existed in Suining main urban area, and the totality trend of the urban heat island effect during 2011 ~ 2016 was downtrend. The heat island intensity of Suining main urban area in summer was strongest, and closely followed by spring. The analysis results based on the MODIS satellite data showed that the urban heat island area of Suining main urban area gradually enlarged from 2011 to 2014. The strong heat island area and strongest heat island area were concentrated mainly in downtown area. The urban heat island effect was remitted during 2016 ~ 2017, and the strong heat island area and strongest heat island area were eliminated. The urban heat island effect under extreme high-temperature in 2017 was weaker than 2006. The sponge city construction increased the green land area and water area of Suining main urban area, changed the urban road and legitimately planned the urban construction, which remitted the heat island effect of Suining main urban area. |
