In　the　process　of　China＇s　modernization,　promoting　the　sustainable　development　of　resource-based　cities　is　a　major　strategic　issue　and　it　has　now　also　become　a　worldwide　issue.　This　study　uses　the　coupling　model　to　validate　the　coupling　relationship　between　China＇s　land-use　net　carbon　flux　and　economic　growth　and　population　change　during　2009-2017.　The　study　for　the　first　time　draws　the　conclusion　that　the　coupling　degree　among　the　three　is　getting　lower,　the　correlation　is　gradually　weaker,　and　the　independent　relationship　is　becoming　more　and　more　prominent.　Utilizing　the　Tapio　decoupling　model,　we　obtained　the　weak　decoupling　conclusion　that　the　economic　growth　rate　is　higher　than　the　growth　rate　of　the　land-use　net　carbon　flux,　while　negative　decoupling　of　sprawl　is　where　the　rate　of　population　growth　is　less　than　the　rate　of　net　land-use　carbon　flux　growth.
