Based　on　the　decoupling　theory,　the　article　constructs　decoupling　indicators,　and　calculates　total　decoupling　index　of　China,　decoupling　index　of　different　energy　sorts　and　industries,　according　energy　consumption　data　of　China　between　1980　and　2009.　It　analyzes　the　changing　relationship　between　economic　development　and　energy　consumption　in　different　times　and　on　different　aspects,　concludes　that　the　total　decoupling　index　of　China　increase　steadily,　that　the　relevance　of　different　sorts　of　energy　is　insufficient,　that　the　decoupling　index　of　tertiary　industry　is　too　high.　(C)　2011　Published　by　Elsevier　Ltd.　Selection　and/or　peer-review　under　responsibility　of　RIUDS
