中文摘要 | 土壤流失是造成土地資源耗損的原因之一,輕者如表土流失,重者則地力盡失、土壤劣化,而引發土壤流失的機制有天然降雨及人為開發,因此研究土壤流失的控制方法或推估流失量則成為土地資源保育重要課題。本研究特別針對世界各地廣泛應用的通用土壤流失公式(Universal Soil Loss Equation, USLE)及具理論基礎且準備取代前二者經驗公式而研發的水蝕推估模式(Water Erosion Prediction Project, WEPP)應用於台灣中部茶園的評估差異加以分析比較,結果顯示USLE模式及WEPP模式的模擬值略低於實測值,而WEPP模式的土壤流失量推估值與實測值最為接近。 |
英文摘要 | Soil erosion is one of causes of land resource consumption. Surface soil loss is the slight case. Soil fertility losses and the soil deterioration are the most severe cases. There are two mechanisms of soil loss: natural rain and human development. Hence, soil erosion control method or soil loss estimation is a very important research topic in land resource conservation. USLE, and WEPP were applied to simulate the runoff and soil loss on tea plantation in this study. Among all models studied, the simulation result of WEPP is the most closest to the measured soil loss. |
