Abstract With the support of remote sensing and geographical information system, the land use/land cover maps of the coastal wetland in Jiangsu were obtained by classifying three-period Landsat TM/ETM+ images, and the land surface temperature (LST) was retrieved by mono-window algorithm. Based on the classification maps and LST of 1992, 2002 and 2009, the authors investigated the land use/cover change and corresponding LST responses. The results show that the major land use/cover changes are dominated by human activities, and the most obvious change trend is from natural land cover types to manmade land use types, demonstrating that human activities are the main driving forces of wetland change. Corresponding to the land use/cover change, the land surface temperature patterns are also affected obviously, specifically, a certain degree of temperature increase trend was observed.
