[ 摘要 ]
過去山崩模式分析多針對單一地震或颱風事件來進行研究。對於台灣中部區域而言，兩者皆觸發大量山崩發生。此外，對於植生復育的舊山崩，在國內過去的山崩模式分析裡也甚少被加以考慮。根據經濟部中央地質調查所於2004年8月25日侵台的艾莉颱風調查報告中可發現，艾莉颱風觸發的山崩多為舊山崩復活。因此，舊山崩為一個相當重要的因子，必須納入模式中加以考慮。
本研究對於集集地震後與桃芝颱風後的航空照片進行山崩判釋，並將判釋之山崩圖層進行合併。選擇（1）地質－岩性、與構造距離（2）地形－坡度、坡向、高程（3）環境－PGA、累積雨量、與溪溝距離、土壤種類、土地利用共十項因子以航照產製之5mX5m DTM和不安定指數法加以評估並建立模式。最後應用此模式製成山崩災害圖，並與判釋結果加以比對。此模式可以有效的找出山崩崩壞比較高的區域，在模式重新分類後亦可掌握大部分的山崩面積。

[ 英文摘要 ]
Most landslide model analyses treat the earthquake and typhoon event Individually.
Both events have triggered many landslides at central Taiwan. Nevertheless, the vegetation recovered old landslides are seldom considered into analysis. For such process, most landslides are classified as old landslides triggered by typhoon Aere,attack Taiwan on Aug 25th 2004, investigation reported by the central geological
survey. For this reason, old landslide is an important factor that must be considered into the model.

The study mapping landslides form the aerial photographs after the Chi－Chi earthquake and Typhoon Toraji. Furthermore, merge the landslides maps, select(1)Geology－lithology、distance to geological structure (2) Terrain－slope angle、aspect、Elevation (3) Environment－PGA、cumulate rainfall、distance to gully、soil
type、landuse total using of ten factors. Using 5mX5m DTM made by the aerial photographs to build the model then evaluate with instability index method. Finally,apply the model to create a landslide hazard map and compare with the actual landslide mapping result. The model can find the higher hazard area effectively, and after reclassify the model, it can also include most of the landslide area.
