On　the　research　of　contrastive　analysis,　this　paper　discusses　the　environmental　impact　of　high-speed　maglev　and　high-speed　wheel-rail　in　land　use,　noise　pollution,　energy　consumption,　ecological　effect,　electromagnetic　radiation　and　other　aspects.　On　this　basis,　this　paper　describes　the　influences　on　environment　of　high-speed　maglev　in　transit　system　of　China,　and　puts　forward　the　concrete　opinions　and　suggestions　for　the　engineering　investigation,　construction,　and　environmental　impact　assessment　of　high-speed　maglev.　Adopting　the　linear　motor,　maglev　system　has　the　characteristic　of　low　noise,　and　which　does　not　produce　machinery　noise　via　a　way　of　no　touch　to　put　support,　guide,　driving,　braking　and　power　supply　into　effect,　and　aviods　the　interface　contact　of　trains.　There　are　aerodynamic　noises　chiefly　when　the　maglev　is　moving　with　high　speed.　Meanwhile,　maglev　system　is　one　mode　of　energy-conservation　transportation,　which　emits　no　harmful　substance　in　operation.　And,　since　the　magnetic　intensity　of　maglev　is　somewhat　above　which　of　the　magnetic　field　of　Earth,　which　seems　harmless　to　the　human　body.　Maglev　runs　very　quietly　in　low　speed,　which　shows　a　predominance　of　environmental　protection,　compared　with　urban　elevated　rail　and　elevated　highway.　Moreover,　in　high　speed,　maglev　can　run　along　the　existing　transportation　corridor　without　costing　too　much　land　resources,　and　also　ease　the　burden　on　the　environment.　©　2010　IEEE.
