摘要

地質法施行之後，中央主管機關即著手規劃與進行地質敏感區的劃定作業，本文主要在探討如何參考使用現有地質環境資料，來劃定山崩與地滑地質敏感區之構想；同時傳達現階段劃定山崩與地滑地質敏感區之目的，以揭露（公告）可能受到自然或人為影響而有山崩與地滑之虞地區。並進一步討論涉及地質敏感區的土地開發行為，在進行基地地質調查及地質可適性評估時的操作建議，因應地質可適性，並採行合宜的處理對策，也希望能夠間接達到保護坡地穩定的目的。另外，蒐集他國坡地災害劃定方式，以及其災害圖架構與行政管理策略，做為地質敏感區劃定與公告後，因應土地行政管理之配套措施，依法於5年後於劃定作業通盤檢討時，他山之石也可做為精進山崩與地滑地質敏感區劃定方法之借鏡，期望能達到國內坡地安全與經濟開發雙贏的局面。

After implementation of the Geology Act, the central competent authority started to deal with the planning and delineation of geologically sensitive areas. This article focuses on the conception of using existing geological environment data for the delineation of landslide-landslip in geologically sensitive areas. Simultaneously, we aim to alert the public existence of areas potentially susceptible to landslides and landslips induced by nature or human activities. We went further to discuss matters related to the development of geologically sensitive areas: in conducting geological site survey or assessing geological safety adaptability, appropriate coping measures are taken, which also indirectly accomplishes the task of stabilizing slopes. In addition, we collate as reference how other countries handle slope hazards, including their methodology and framework in geological hazard map treatment. After the delineation and announcement of geologically sensitive areas, in response to measures of land administration and overall review of the delineation operation, the experiences from other countries would be drawn as reference for sophisticating the delineation of geologically sensitive areas. We hope to make both slope safety and economic development a win-win accomplishment.
