摘要: 
本研究以關刀溪森林集水區為對象,以長期蒐集之降雨逕流資料並應用水筒模式之方法嘗試建立一套用於估算本區之降雨與逕流之模式。並以此模式之模擬資料與實際觀測資料相比較,探討本區之流動特性。其由結果摘要如下:
1.兩段式水筒模式於逕流總量之模擬上有良好之效果。
2.本試區之土壤水份消乏量甚小,對降雨產生之逕流影響不大。
於長時間乾旱後,土壤水分消乏量可能會有所增加,致使降雨初期之模擬流量高出實際流量甚多。
3.本試區之稽延時間與集流時間皆低於1小時。
4.本試區暴雨逕流之型態以暴雨潛流為主。
5.本試區基流流量遞減速率主要受深層地下水滲漏量佔地下水量之多寡所影響。
6.於估計集水區之地下水補注量時,採用表土層底部水分向下滲透之速率較採用地表入滲率適合。

The long-term rain and runoff data in Guandaushi Forest Watershed were used to establish a tank model to estimate rain and runoff.In other to understand the quality of the rundoff in Guandaushi Forest Watershed, the result of the simulation on tank model were used to compare with the observation data. The results were summarized as follows:
1.The simulation on two step tank model made better results with total runoff.
2.The soil moisture deficiency had less influence with the runoff.But with a longer arid time, the soil moisture deficiency might be increased and the result of the simulation would be bigger than the observation data.
3.The lag time and concentration time was less than one hour.
4.The master of the direct runoff was interflow.
5.The decreased of the base flow was be influenced by the rate of the deep percolation loss on groundwater.
6.Useing the infiltration rate between the surface soil and the layer under the surface soil to estimate gruondwater recharge was much fit than using the infiltration rate on the surface of ground.
