台灣地區是一個颱風和地震等自然災害頻仍的地區。其所引發的山崩和土石流也造成了相當多的生命財產損失。從土地使用計畫的觀點，吾人必須充分考慮各種潛在因子，妥善擬訂土地利用計劃，避免無謂的損失。然而，基本資料的欠缺，一直是個很根本的問題。本研究從實際災害、潛在敏感、土地使用現況、土地使用計畫等四類現有的資料著手，透過空間疊合分析，試圖發現其間所存在的關聯、矛盾與衝突，以做為後續研究的參考。

Thereare frequently natural disasters， causing collapses， slides， floods and life and property loss， in Taiwan. From the viewpoint of land use planning and management， planners have to make appropriate plans based on sufficient and correct information. However， this kind of ideal data does not exist. Thisarticle analyzes some existing data sets and trys to figure out spatial corelation among them. It is hoped that the preliminary results can provide directions for further studies.
