利用卫星遥感对城市热岛进行监测研究在国内是相对的薄弱环节,国外这方面的文献也很少。在城市热场详查中航空遥感优于卫星遥感。但是航空遥感费用大,不能经常飞行观测,这是不能满足城市热岛研究的。卫星遥感具有范围广、准同步、周期短、费用低等优点,对城市热岛的动态监测是有利的,并且可在大区域范围内对不同城市及城市与乡村之间的热场分布和变化进行对比研究。随着卫星图像分辨率越来越高,显示着利用卫星遥感研究城市热岛的广阔前景。
Monitoring the urban heat island using satellite remote sensing is relatively weak in China, and there are few overseas literature. Airborne remote sensing is better than satellite remote sensing in the detailed investigation of the urban thermal field. However, the cost of aviation remote sensing is large and frequent observation can not be conducted, which can not satisfy the study of urban heat island. Satellite remote sensing has the advantages of wide range, quasi-synchronization, short period and low cost. It is beneficial to the dynamic monitoring of urban heat island, and it can conduct the distribution and change of the thermal field in different cities and between cities and villages in a large area Comparative Study. With the increasing resolution of satellite images, it shows the broad prospect of using satellite remote sensing to study the urban heat island.
