The　impact　of　human　activities　on　ecosystems　is　receiving　increasing　attention　because　their　mechanisms　of　action　are　complex;　the　spatial　response　of　ecosystem　service　drivers　still　needs　to　be　explored　further.　This　study　evaluated　three　ecosystem　services-water　yield,　soil　conservation,　and　carbon　storage-in　Hainan　Province　from　2000　to　2020;　we　analyzed　the　spatial　and　temporal　changes　of　the　ecosystem　services,　and　the　spatial　heterogeneity　of　the　influencing　factors.　The　results　were　as　follows:　(1)　The　average　water　yield,　soil　conservation　and　carbon　storage　of　Hainan　Province　from　2000　to　2020　were　42.36　billion,　8.01x108　t　and　1.52　x　107　t,　respectively.　Overall,　the　ecosystem　services　were　relatively　weak　at　lower　elevations.　(2)　There　were　obvious　hot　spots　and　cold　spots　in　the　water　yield　and　soil　conservation,　and　the　hot　spot　distribution　of　carbon　storage　was　not　obvious.　(3)　There　were　differences　between　the　ecosystem　services　for　different　land　use　types;　trade-off　relationships　only　appeared　between　unused　land　and　ecosystem　services.　(4)　The　precipitation,　normalized　difference　vegetation　index　and　elevation　factors　had　great　impacts　on　the　ecosystem　services.　Most　of　the　human　activity　factors　showed　a　significant　nonlinear　enhancement　effect　during　their　interaction.　Population　and　elevation　had　obvious　spatial　differentiation　effects　on　the　water　yield　and　carbon　storage　services.
