摘要: 
臺灣自然環境山脈陡峭、山坡地面積占全島三分之二,在人口日益增長的情況下,山坡地保育重要且急迫。
國內的土壤流失量估算研究,主要是使用通用土壤流失公式(USLE)作為一地區之土壤流失量的估算,或是將USLE內之因子修正,使其更符合臺灣地區的運用。
本研究使用斜坡單元法,將相似坡度及坡向劃分為一斜坡單元坵塊,使其可視單一均勻之地形單元。再將每個單元之USLE因子運用ArcGIS數化及擷取各式圖資,推估出各個斜坡單元的年平均土壤流失量,並轉換為年平均土壤流失深度。
結果顯示,應用斜坡單元法推估USLE之年平均土壤流失量,平均為98.7 ton/ha,流失深度則為0.70 cm,其結果受覆蓋及管理因子(C值)影響最深。
沖蝕查定是根據地籍坵塊作為查定的單元,其劃分並無任何地形概念,若未來能將山坡地運用斜坡單元法劃分及編號所有之斜坡,將其納入查定之輔助工具之一,對山坡地土地可利用限度分類、管理及保育將會有更顯著的幫助。

Two third of Taiwan area is covered by slopeland and mountains. With more and more population, it is indispensable and urgent to protect slopeland in Taiwan.
For domestic soil loss research, Universal Soil Loss Equation(USLE) is widely used to estimate soil erosion for a certain area. To be more specific, some factors are modified so that the equation would be more suitable for the applications in Taiwan.
Slope units method is applied in this research. Similar slope and aspect are regarded as one slope unit, and uniform terrain unit is assumed. Then graph and statistics are attained by applying USLE factors ArcGIS digitalization. The average annual soil loss for every slope unit estimated, which can be transformed to average annual depth for soil loss.
The results showed that application of slope unit method by using USLE to estimate soil loss, an average soil loss is 98.7 ton / ha, the equivalent depth is 0.70 cm. The coverage and management factor (C) affect the soil loss estimation tremendously.
Cadastral unit is the base to determine soil erosion. There is no concept of divided terrain. If slopeland can use slope unit method to divide and number all of the slopes in the future, and can be applied as a support tools to determine the soil degree. The slope unit method will have a significant help for the classification of slopeland use limitation.
