摘要

Philip一維度入滲模式，因含有吸著力與相當於飽和土壤導水度的兩項參數，具有物理意義，頗為坡地水文界所採用。本研究經由野外模擬降雨試驗，量測台灣中部蓮華池與畢祿溪兩地不同地被土壤最終入滲率，其結果依大至小排列為：天然林、草生地、竹林、砍伐跡地、果園、杉木造林地及裸露地。並證實Philip入滲模式之兩項參數可由野外入滲試驗數據決定；且最終入滲率與土壞粗孔度的相關性甚為顯著。

Hillslope hydrologists often use Philip's equation to predict infiltration because the equation was developed from a physical basis. Philip's equation contains two parameters: sorptivity and parameter related to the soil saturated hydraulic conductivity. Two parameters in this equation have physical meaning. Simulated rainfall was applied to test plots with different land covers in Lien-hua-chi and Pi-lu-chi areas, central Taiwan. Eased on the results, the final infiltration rate of respective test plot in decreasing order was as follows: natural forest, grass land, bamboo plantation, def crested land, orchard, China-fir plantation and bare land. The values of two parameters of Philip's equation have been determined by data from test plots with simulated rainfall. The relationship between the final infiltration rate and soil macro-porosity was found significant.
