Land　use　and　resource　depletion　are　two　main　considerations　in　life　cycle　assessment　(LCA).　Unfortunately,　the　relationship　between　land　use　and　resource　depletion　is　always　ignored　and　only　a　few　studies　tried　to　connect　them.　The　objective　of　this　paper　is　to　establish　an　exergy-based　model　for　quantifying　land　resource　in　China,　which　includes　both　the　occupation　phase　and　the　renaturalisation　phase　of　land　use,　and　implement　this　model　into　a　case　study　on　sintered　brick　production.　The　results　show　that　the　exergy　loss　caused　by　land　use　accounts　for　an　innegligible　percentage　in　the　cumulative　exergy　extracted　from　natural　environment　(CEENE)　of　sintered　brick;　the　results　also　show　that　the　duration　of　renaturalisation　and　the　type　of　land　are　the　cardinal　factors　for　improving　the　accuracy　of　results.
