Abstract:In all urbanization′s eco-environment effect, greater consideration was put on thermal environment. Urban thermal environment was co-influenced by land surface physical properties and human social and economic activities, which is a synthesis manifest of urban eco-environment. In all urban landscape types, the thermal environment effect of park landscape is very different with the other landscape types. Studies on thermal environment effect of urban park landscape are of great significances for urban planning and urban eco-environment evaluating. Spatial data of urban park landscape patches and land surface temperature obtaining, thermal environment effect of landscape patch characters are discussed in this paper, using the data collected by the Landsat 7 Enhanced Thematic Mapper Plus (ETM+) and spatial analysis function of GIS in the city of Shanghai. For the spatial pattern of urban thermal environment in Shanghai city, this has an intense urban heat island effect. Heat island center lies on the west bank of Huangpu River. There is an intense temperature variance in the inner of heat island. For example, there are some low temperature valleys associating with parks. There are apparent negative correlativity between area, perimeter of park landscape patches and its associate with temperature. There is an apparent positive correlativity between shape complexity index of park patches and environment temperature, which is much significant than that of area and perimeter. There are not apparent statistically relationship between area, perimeter of park patches and park′s influence on around thermal environment. By contrast there is a significant positive correlativity between shape complexity index of park patches and park′s influence on around thermal environment, the shape is more complexity the influence is more intense. So in urban park buildings, except for park types and special location selection, the outline shape of park should be a considered factor for urban thermal environment.
