摘要

在水稻梯田之降雨－逕流模擬上，水筒模式與線性水庫能確實掌握流量模擬的變化趨勢，並結合參數自動率定法其參數率定方式更增效率及準確性。本研究利用水筒模式與線性水庫，分別對於水稻梯回來進行逕流模擬與參數分析之研究。擬以新竹縣新埔鎮大茅埔段之水稻梯田爲試驗區，於試驗區之入流點及由流點處設置自記式水位計與雨量計，收集流量、雨量實測資料來進行模擬與探討。研究結果顯示水筒模式整體模擬均優於線性水庫。

On a rainfall-runoff simulation of terraced paddy field, tank model and conceptual mode of linear reservoirs were applied to rainfall measurement in the simulation, and also automatic calibration method was used in the simulation to enhance its efficiency and accuracy. The research is to simulate the rainfall-runoff of a terraced paddy field by tank model, conceptual mode of linear reservoirs, and automatic calibration method. The terraced paddy field in Hsuing-Pu Hsiuing-Chu was selected to be our subjects. In this experimental field we arranged water-stage automatic recorders and automatic rain gauges at the entrance and the outlet of the flow to gather the data of rainfall in this region for rainfall-runoff simulation. The result showed that tank model surpassed conceptual model of linear reservoirs.
