Paper Abstract

This paper discussed the impact of the distribution of parks including water bodies on the relief of urban heat. An image of QuickBird on Aug. 30, 2013 was employed to perform the detailed land cover classification. One swath of Landsat 8 THIR image was collected to derive the land surface temperature. After some necessary preprocessing procedures, object-based classification method was used to classify the land cover as residential region, square and road, water body, as well as park. The results showed that water bodies and parks play an important role in reducing the land surface temperature. Grass, shrub and trees were extracted out respectively by manual from parks that were adopted to test the influence of proportions among trees, shrubs and grass on the fluctuation of land surface temperature in urban area. The results achieved in this paper could be helpful for the local governments to make a decision in urban plan and management.
