摘要：

Based　on　three　scenarios　of　different　energy　usage　strategies,　a　quantitative　evaluation　of　the　environment　load　caused　by　magnesium　production　using　the　Pidgeon　process　in　China　was　carried　out　according　to　the　theory　and　framework　of　LCA　study.　The　results　showed　that　the　fuel　used　in　the　process　was　the　major　contributor　to　the　pollutants　emission　of　magnesium　production.　Global　warming　potential　and　acidification　potential　make　the　main　contribution　to　the　accumulative　environmental　impact.　The　different　fuel　use　strategies　in　the　practice　of　magnesium　production　caused　many　different　impacts　on　the　environmental　performance.　The　accumulative　environmental　load　of　coal　burned　directly　(Scenario　1)　was　highest,　and　that　of　Scenario　2　and　Scenario　3　decreased　respectively　by　9.3%　and　29.5%　comparing　with　the　result　of　Scenario　1.
