Urban　heat　island　intensity　(UHII)　is　an　important　metric　used　in　measuring　Urban　heat　island　(UHI)　effect.　Nevertheless,　its　quantitative　measurement　has　not　yet　been　clearly　addressed.　Due　to　the　limitation　of　meteorological　stations　either　in　their　number　or　location,　the　traditional　method　which　calculates　the　temperature　difference　between　urban　and　rural　areas　based　on　the　meteorological　station　data　fails　to　accurately　describe　the　UHII　of　a　city.　In　order　to　work　out　this　problem,　Steward　and　Oke　proposed　a　classification　schema　-＂　Local　Climate　Zones＂　(LCZ).　This　paper　applied　the　new　framework　of　LCZ　to　the　study　of　UHII　in　Fuzhou　using　remote　sensing　technology.　Fuzhou　has　witnessed　a　rapid　urban　expansion　process　since　the　late　1970s.　The　fast　expansion　of　the　city　has　caused　severe　UHI　phenomenon　occurring　in　the　city　and　thus　to　have　become　the　top　one　furnace　city　in　China.　The　study　reveals　that　the　remote　sensing　technology　based　LCZ　can　effectively　distinguish　the　thermal　contrasts　among　all　LCZ　classes.　In　addition,　the　LCZ　can　fully　disclose　the　distribution　patterns　of　UHI.　In　this　study,　we　revealed　a　UHIILcz　of　6.73　degrees　C　for　Fuzhou　city　on　27　September　2015,　which　indicates　an　intensification　of　the　UHI　in　the　city.
