With　the　global　warming,　the　rapid　urbanization　process　and　the　increasing　intensity　and　scope　of　human　activities,　extreme　high　temperature　and　cooresponding　high　temperature　events　were　frequent,　meanwhile,　the　degree　of　urban　exposure　to　high　temperatures　was　growing.　The　research　constructed　the　heat　exposure　evaluation　index　system　by　taking　the　heat　exposure　evaluation　index　system　in　Xiamen,　a　gulf-based　city　with　high-temperature.　This　study　evaluated　the　influence　factors,　spatial　differentiation　features　and　hotspots　of　the　heat　exposure　based　on　the　methods　of　geo-spatial　analysis,　emergy　accounting　theory,　expert　consultation　and　analytic　hierarchy　process　in　Xiamen.　The　research　results　were　expected　to　promote　the　theoretical　development　of　urban　heat　exposure　researches,　and　to　provide　decision-making　reference　for　heat　exposure　assessment,　regulation　and　adaptation　in　Xiamen　and　similar　high　temperature　cities.　©　The　Authors,　published　by　EDP　Sciences,　2018.
