摘要

全無崩坍跡象之山坡地潛在災害地區之預測，對於土地資源調査和土地利用之合理規劃，以及工程地質之研究等極爲重要，惟因其問題之複雜，迄未發展出系統化和科學化之方法。本研究從分析各種崩山類型之地形和地質條件著手，並綜合之，以爲工程環境地質調査參數，並將成果製成工程環境地質圖。圖中之土地單元之參數若具備發生某種崩山類型之組合時，該土地單元即爲該類型崩山之潛在災害區。本論文同時討論研究成果如何應用於山坡地開發之環境影響評估。

Prediction of potential landslide area without any detectable surface features is of great importance to land resources investigation, land use planning, and engineering geological studies. However, because of its complexities in nature, no systematic and method has yet been developed. The present study analyzes the particular geomorphological and geological conditions which are regarded essential to the occurrence of each type of landslides. Those factors that are found to be present in every kind of landslides are then selected as parameters for engineering environmental geoloical mapping. And the land unit whose of which the combination of the parameters form the conditions for certain type of landslides is regarded as the potential area for that type of landslide to occur under adequate triggering forces. The applications of the results to the environmental impact assessment of slopeland development are also discussed.
