On　the　basis　of　the　extended　Kaya　identity　and　by　means　of　LMDI,　the　writers　analyze　quantitatively　the　4　factors　including　carbon　emission　intensity　of　planting,　agriculture　structure,　economical　level,　and　population　size,　etc.　thus　giving　effects　to　changes　of　carbon　emissions　from　agricultural　production　in　Sichuan　Province　from　1997　to　2010.The　results　show　that　carbon　emission　intensity　of　planting　and　agriculture　structure　have　brought　negative　effects　to　the　growth　of　carbon　emissions.　These　effects　will　come　into　being　more　and　more　obviously.　Economic　level　played　a　direct　role　in　growth　of　carbon　emissions,　which　is　considered　to　be　their　greatest　and　everlasting　contributor　in　respect　of　growth　of　carbon　emissions.　The　contribution　of　population　size　keeps　pace　with　carbon　emissions　basically.　These　reflect　Sichuan　Province　have　made　some　achievements　in　adjusting　the　agricultural　structure　in　recent　years.　The　rural　population　have　been　maintained　under　stable　control　in　Sichuan.　Meanwhile,　with　its　economic　development,　the　agriculture　modernization　has　been　improved　gradually　paying　attention　to,　such　as　agriculture　mechanization,　chemization,　irrigation　and　the　demand　for　energy　consumption　keeps　on　rising.　Finally,　carbon　emissions　have　increased　in　agricultural　production　of　Sichuan　Province.　©　(2014)　Trans　Tech　Publications,　Switzerland.
