    Abstract: 近年來，臺灣地區山坡地開發，使得土壤沖蝕現象更加惡化。爲了有效規範山坡地開發，確實作好水土保持，有效的土壤沖蝕評估是當前刻不容緩的工作。本研究目的是針對影響土壤沖蝕諸多因子中，與土壤本身關係最密切的因子「土壤沖蝕性指數」進行修訂，利用已建立的土壤沖蝕性資料庫，重新分析各土壤質地，得出簡易土壤質地與土壤沖蝕性指數的迴歸公式，使詳細土壤分析資料不易求得的地區，也能利用土壤質地分類求得所需的土壤沖蝕性指數。同時可進一步簡易化、一致化此複雜推估技術，達到落實土壤沖蝕研究技術及推廣至使用者階層，確保水土資源永績不絕利用。
    In recent years, intense development on steep slopes has resulted in rapid erosion induced environmental deterioration. Thorough assessment of soil erosion problem is, therefore, necessary to guarantee proper slopeland development and appropriate soil and water conservation practices. The main objective of this study is to re-evaluate one of the soil erosion factors that concerns the soil itself、which is the soil erodibility factor. A reliable regression equation has been estab1ished between the soil erodibility values and the soil textural classes. This allows easier application of soil erodibility factor which is beneficial to the actual implementation of soil erosion prediction tech nology and widespread application of this technique on the users level. Furthermore, this effort will also ensure future sustainable development of soil and water resources in Taiwan.
