Description
To mitigate the urban heat environment, it is now becoming common practice to increase natural vegetation such as trees and grass. Particularly, the planting of greenery on roof-tops and on the walls of houses, buildings etc. has been promoted by many municipalities. However, it is also important to plant greenery in unused areas to increase the vegetation. In fact, covering unused areas with greenery not only has an effect on mitigating urban heat environment, but also offers a place of recreation and relaxation to people. In this study, first, we extracted the green covers such as trees and grass by using the high resolution satellite imagery, IKONOS. Then, we merged the land use data and greenery (LUG). We also acquired the land surface temperatures (LST) during different seasons and times. After which, we analyzed relationship between the LUG and the LST data. We also simulated mitigation effect of urban heat environment by planting greenery in unused areas.
