摘要

本研究利用單筒式滲漏計與Guelph滲透計量測茶園不同處理區之土壤飽和水力傳導度，結果顯示，利用單筒式滲漏筒所測得之飽和水力傳導度較大，且不同處理區間有較大的變異值；而Guelph滲透計所測得之飽和水力傳導度較低，且各處理區間之變異較小。

並列摘要

Field experiments were conducted to compare the saturated hydraulic conductivity (Ks) measured by two different techniques: Single Ring Infiltrometer (RI) and Guelph Permeameter (GP). The Ks value obtained from the RI method are higher and have greater variability than that obtained by the GP method. Different soil conservation practices would affect the saturated hydraulic conductivity.
