Rapid　urbanization　has　made　urban　space　thermal　environment　(USTE)　problems　increasingly　prominent.　USTE　research　is　important　for　improving　urban　ecological　environment　and　building　energy　consumption.　Most　studies　on　USTE　research　progress　have　focused　on　meteorological　observations　and　remote　sensing　methods,　and　few　studies　on　USTE　are　based　on　computational　fluid　dynamics　(CFD).　During　the　past　two　decades,　with　the　increasing　applications　of　CFD　in　USTE　research,　comprehensively　summarizing　the　phased　results　have　become　necessary　tasks.　This　paper　analyzes　the　current　research　status　of　CFD-based　USTE　simulation　from　six　perspectives.　First,　we　summarize　the　current　research　status　of　USTE　simulation　with　CFD　models　that　integrate　ground　observations　and　remote　sensing　technology.　Second,　we　define　and　classify　the　spatial　scope　of　CFD-based　USTE　simulations　at　different　scales.　Third,　we　systematically　analyze　the　quantitative　relationships　among　urban　land　type,　the　underlying　surface　structure,　water　bodies,　green　space　and　the　corresponding　changes　in　CFD-based　USTE　simulations.　Fourth,　we　quantitatively　analyze　the　impact　of　anthropogenic　heat　in　CFD-based　USTE　simulations.　Fifth,　we　summarize　the　corresponding　USTE　mitigation　measures　and　methods　based　on　the　CFD　simulation　results.　Finally,　the　outlooks　and　the　existing　problems　in　current　research　on　CFD　simulations　of　the　USTE　are　analyzed.
