Under　accelerated　urbanization　and　high-intensity　human　activities,　the　natural　wetlands　distribution　area　(NWDA)　in　Minjiang　River　estuary　faces　the　great　challenge　of　a　deteriorative　urban　thermal　environment.　This　work　aims　to　analyze　the　impact　of　land　use/land　cover　(LULC)　on　the　urban　thermal　environment　and　model　wetland　surface　temperature　disturbance　characteristics　during　the　process　of　urbanization.　The　study　utilized　the　following　methodological　steps:　(1)　mapping　of　LULC　spatial　and　temporal　distribution　through　photo　interpretation;　(2)　applying　the　mono-window　algorithm　to　obtain　the　spatiotemporal　patterns　of　land　surface　temperature　(LST);　(3)　examining　the　correlation　between　LST　and　different　LULC　classes,　normalized　difference　vegetation　index　(NDVI),　normalized　difference　moisture　index　(NDMI),　and　normalized　difference　impervious　surface　index　(NDISI);　and　(4)　exploring　wetland　surface　temperature　characteristics　based　on　profile　analysis　and　regression　models.　The　results　showed　that　the　LST　pattern　depended　on　the　LULC　distribution;　the　high　LST　zones　were　mainly　observed　in　the　center　of　Fuzhou　city,　and　the　low　LST　zones　were　mainly　observed　in　forest　and　river　areas.　Moreover,　the　urban　thermal　environment　was　influenced　by　both　LULC　classes　and　urban　growth　types.　Finally,　the　positive　relationship　between　LST　and　NDISI　indicated　an　amplifying　effect　of　the　impervious　surface　for　wetland　surface　temperature,　while　vegetation　with　high　liquid　water　attenuated　the　regional　high　temperature.　The　obtained　conclusions　are　expected　to　be　beneficial　in　improving　the　design　and　management　of　the　urban　thermal　environment.　©　2019,　HARD　Publishing　Company.　All　rights　reserved.
