Fujian　Province　is　the　first　＇National　Ecological　Civilization　Experimental　Zone＇　approved　by　the　State　Council　of　China.　As　the　provincial　capital,　a　good　ecological　environment　for　Fuzhou　City　is　always　expected.　During　the　progress　of　urbanization,　Fuzhou　has　witnessed　a　significant　urban　thermal　environment　(UTE)　change,　leading　the　city　to　be　reputed　by　media　as　the　top　one　of　the　three　new　＇furnace　cities＇　in　China.　To　investigate　the　process　of　the　city　from　a　non-furnace　city　to　a　top　furnace　city　in　China,　the　dynamics　of　urban　biophysical　components　of　Fuzhou　and　the　associated　UTE　between　1989　and　2013　have　been　analyzed　by　remote　sensing　technology.　The　result　shows　that　the　urban　heat　island　(UHI)　effect　in　Fuzhou　greatly　aggravates　as　the　UHI　Ratio　Index　(URI)　of　the　city　increases　from　0.29　to　0.53　in　the　past　24　years.　The　spatiotemporal　variation　analysis　on　the　basis　of　the　thermal　profiles　reveals　that　the　spatial　structure　of　the　UTE　is　greatly　influenced　by　the　spatial　pattern　of　land　cover　types.　On　the　whole,　the　increase　and　amalgamation　of　impervious　surface　patches,　reduction　and　fragmentation　of　vegetation　and　water　covers,　and　the　blockage　of　the　urban　ventilation　are　the　main　factors　contributing　to　the　formation　of　the　＇furnace　city＇　of　Fuzhou.　The　study　provides　a　guidance　and　support　for　the　mitigation　of　the　UHI　effect　and　the　achievement　of　city＇s　healthy　sustainable　development.　©　2017,　Editorial　Department　of　Journal　of　Tongji　University.　All　right　reserved.
