The　Xiong’an　New　Area　is　a　recently　established　state-level　new　area　in　Baoding,　Hebei　province,　China.　Green　construction　and　development　are　the　most　important　issues　to　be　considered　and　must　be　given　priority　by　area　planners　during　forthcoming　construction　of　the　new　area.　Green　ecological　planning　cannot　be　implemented　without　a　clear　understanding　of　an　area’s　ecological　status　and　an　accurate　prediction　of　an　area’s　ecological　status　responding　to　forthcoming　regional　planning.　Therefore,　using　Landsat　images　of　2004　and　2015,　feature　inversion　and　extraction　techniques,　and　the　remote　sensing-based　ecological　index　(RSEI),　this　study　investigated　changes　in　three　main　land　cover　types　(impervious　surface,　vegetation,　and　water)　in　the　Xiong’an　New　Area　over　the　last　11　years　from　2004　to　2015　and　predicted　the　ecological　and　thermal　effects　responding　to　the　upcoming　regional　construction　on　the　new　area.　The　results　show　that　the　areas　of　impervious　surface,　vegetation,　and　water　covers　have　changed　over　the　11-year　study　period,　but　the　change　intensity　was　less　than　5%.　In　addition,　the　ecological　status　was　stable　during　the　study　period　as　the　RSEI　increased　only　slightly　from　0.629　in　2004　to　0.639　in　2015.　Therefore,　the　overall　development　intensity　was　relatively　low,　and　the　area’s　current　ecological　quality　is　good.　Quantitative　analysis　indicates　that　the　area　of　impervious　surface　has　the　strongest　influence　on　both　ecological　quality　and　land　surface　temperature　among　the　three　main　land　cover　types　of　the　area.　The　area’s　ecological　responses　to　upcoming　regional　planning　were　predicted　using　regression　relationship　models　of　RSEI　and　land　surface　temperature　with　the　three　main　land　cover　types.　The　prediction,　based　on　the　known　goal　of　population　and　area　development,　revealed　that　the　increase　of　population　to　2.5　million　with　a　25%　of　impervious　surface　cover　in　the　new　area　would　have　noteworthy　effects　on　regional　ecological　conditions,　potentially　decreasing　the　area’s　RSEI　by　10　%　and　increasing　land　surface　temperature　by　1.1　℃.　Alternatively,　if　the　proportion　of　impervious　surface　could　be　controlled　within　20%,　the　area’s　RSEI　would　increase　by　3.6%,　and　land　surface　temperature　would　decrease　by　0.3　℃.　©　2017,　Ecological　Society　of　China.　All　rights　reserved.
