China　has　great　potential　for　developing　renewable　energy　to　achieve　its　carbon　neutrality　goals.　Orderly　development　of　renewable　energy　is　essential　to　enhance　resource　utilization　efficiency　and　ensure　safety　during　the　energy　system　transition　process.　This　study　presents　a　thorough　assessment　of　China＇s　onshore　wind　power　potential　by　considering　the　land　suitability,　the　potential　and　temporal　characteristics,　and　the　impacts　of　climate　change.　The　high-resolution　maps　combining　wind　resources　with　land　conditions　and　climate　scenarios　are　produced　to　provide　insights　into　system　planning,　grid　integration,　and　flexibility　management.　The　results　show　that　the　capacity　potential　of　onshore　wind　energy　in　China　is　9.6　TW　with　an　annual　generation　of　12.6　PWh,　and　83　%　of　total　capacity　has　a　cost　advantage　with　the　levelized　cost　lower　than　the　60　$/MWh　threshold.　By　comprehensively　considering　geographical,　economic,　and　social　criteria,　around　8.1　%　of　the　national　territorial　area　is　identified　as　the　most　suitable　area　for　wind　power　development,　primarily　in　Inner　Mongolia　and　Xinjiang.　The　annual　electricity　generation　from　these　areas　can　fulfill　nearly　69　%　of　the　nation＇s　electricity　demand.　Future　climate　change　projections　indicate　a　remarkable　generalized　drop　by　18　%　in　the　north　and　a　slight　increase　by　7　%　in　the　south　under　the　RCP　8.5　scenario.　However,　significant　changes　in　wind　resources　are　mostly　within　restricted　areas,　suggesting　that　future　climate　change　would　like　to　bring　negative　but　limited　impacts　on　wind　power　production　in　China.
