The　objective　of　this　paper　is　to　propose　and　to　construct　the　theoretical　framework　of　highway　landscape　design.　Highway　landscape　has　paramount　significance　of　increasing　highway　traffic　safety　and　reduce　driver＇s　visual　fatigue;　therefore,　it　has　triggered　people　s　attention　more　and　more.　This　paper　puts　forward　the　research　framework　of　the　highway　landscape　after　discussing　the　theoretical　meaning　of　highway　landscape　design,　and　the　authors　think　that　highway　landscape　research　framework　should　include　the　design　principle　of　the　highway　landscape,　the　composition　of　landscape　design　theory　and　landscape　design　indexes　extracting　from　it.　The　proposition　of　highway　landscape　design　theory　framework　has　significant　meaning　of　increasing　traffic　safety　and　advance　the　development　of　highway　landscape　design　theory.
