We　quantified　the　land　surface　thermal　environment　during　urbanization　of　the　main　urban　area　of　Fuzhou　by　extracting　the　land　use/land　cover　(LULC)　based　on　Landsat　series　remote　sensing　data　and　retrieving　the　land　surface　temperature　(LST).　The　results　showed　that　there　were　dramatic　changes　in　LULC　of　Fuzhou　from　1993　to　2013,　with　the　reduction　of　urban　green　space　(UGS)　including　forest/grass,　water　and　wetland　and　the　significant　increase　of　built-up　land.　The　LST　of　different　LULC　had　significant　differences.　The　build-up　land　and　bare　land　had　positive　contribution　to　the　LST,　while　the　UGS　had　negative　effect　on　LST,　with　the　order　of　water　＞　wetland　＞　forest/grass.　During　the　evolution　process　of　different　types　of　UGS,　there　was　a　diversified　temperature　pattern.　The　ALST　caused　by　UGS　loss　was　the　most　obvious,　followed　by　the　UGS　exchange　and　the　UGS　extension　regions.　The　relationship　between　evolution　direction　of　different　UGS　types　and　temperature　effect　was　quantified　by　TVX.　Our　results　might　help　understand　the　mitigation　effect　of　different　UGS　types　on　urban　heat　island　effect　and　provide　useful　reference　to　the　conservation　of　green　space　in　coastal　cities.　©　2019,　editorial　Board　of　Chinese　Journal　of　Ecology.　All　rights　reserved.
