Based　on　the　requirements　of　establishing　urban　earthquake　emergency　shelters　(UEES),　this　paper　lays　emphasis　on　discussion　about　the　calculation　method　of　the　service　area　of　UEES,　which　are　classified　as　3　levels.　The　evaluation　criteria　and　score　of　UEES　are　given.　The　planning　flowchart　of　the　3　levels　of　UEES　is　shown　and　the　corresponding　computer　program　is　developed　in　this　paper.　We　offer　a　method　for　regionalizing　UEES　responsibility　space　based　on　weighted　Voronoi　diagram　(WVD)　through　the　GIS　technology.　Using　the　weighted　radius　of　UEES　responsibility　space　as　the　weights　of　WVD,　7　influential　factors　in　the　radius　are　provided.　We　apply　the　method　to　optiming　zoning　map　of　UEES　responsibility　regionalization,　and　compare　the　result　with　that　from　ordinary　Voronoi　diagram　(OVD).　The　proposed　method　for　UEES　planning　is　verified　through　exemplary　analysis　and　the　result　shows　the　reasonableness　of　the　method　and　it　can　provide　a　simple　approach　for　UEES　planning　and　preparation.
