Analysis of the Impact of Urban Wetland on Urban Temperature Based on Remote Sensing Technology

The typical urban wetland-Xixi wetland was selected as the object of study. The regulation of urban wetland on urban temperature was analyzed quantitatively and qualitatively using Landsat TM remote sensing image of Hangzhou in July 8 th, 2000, July 26 th, 2004 and Aug 12th 2010. The result shows that urban wetland has good regulation on urban temperature, and the closer to urban wetland the regulation on temperature will be more remarkable. The regulation range and extent of urban wetland on urban heat island may vary due to the types of wetland
