| 摘 要： | 随着城市人口的急剧增加,城市建筑规模迅速膨胀,大量热源集中排放,产生了城市内部温度明显高于郊区的特殊城市气候现象,即“热岛效应”.以安徽省芜湖市为研究区域,采用GIS叠加分析方法、缓冲区分析方法进行地表辐射亮温与土地覆盖类型的相关性研究.研究结果表明,辐射亮温与地表类型有明显的相关关系,建筑与辐射亮温的相关系数为0.87,植被、水体与辐射亮温的相关系数分别为0.59、0.78.人工建筑因素是产生热岛效应的主要原因之一,加大植被、水体在城市土地用地中的比重,是控制城市热岛效应行之有效的方法,而且利用辐射亮温图可很好地指示城市土地覆盖类型在时间上和空间上的变化.

| Abstract: | With sharp increase in urban population,rapid expansion in urban construction and the concentrated emission of heat sources,a special urban climate phenomena was produced.The internal temperature of the city was significantly higher than the suburbs,which was known as the urban heat-island effect.This article took Wuhu as the survey region,with the method of GIS spatial overlay analysis and spatial buffer analysis to study the relativity between brightness temperature and land cover.The findings indicated t... |
