The　aim　of　this　study　was　to　make　China　climatic　regionalization　for　highway,　which　provided　reference　for　understanding　effects　of　climatic　conditions　of　China　on　highway.　Requirements　of　highway　on　climatic　regionalization　could　be　divided　into　three　levels　of　basic　requirements,　integrated　requirements　and　macro　requirements.　Service　principle　and　practicability　principle　were　proposed　for　regionalizing.　For　various　level　requirements　of　highway,　climatic　regionalization　should　include　three　levels　of　basic　layer,　integrated　layer　and　macro　layer.　According　to　regionalizing　indicators　of　average　annual　accumulated　temperature　above　20C,　average　annual　freezing　index,　precipitation　in　freezing　period　and　average　annual　precipitation　in　nonfreezing　period,　the　macro　layer　of　the　regionalization,　China　climatic　regionalization　for　highway,　were　suggested　through　methods　of　cluster　analysis,　division　based　on　indicator　and　layers　superposing,　which　included　10　first-level　regions　and　24　second-level　regions.　It　summarizes　that　climate　of　China　affects　highway　in　macro　level.
