Abstract:	台灣地區由於生活水平提高、都市化及工業區和高科技科學園區不斷新設，民生及產業用水遽增，而新水源開發不易且原水成本提高，以致民生及產業用水轉向由農業用水移用之情形日益普遍，雖因農業灌溉擁有缺水忍受度較高的優點，但亦需從影響層面較小的方式進行用水調節，以增加缺水時期的用水彈性空間。農業灌溉方式多由上游處往下游處灌溉，以桃園台地的地形為例，灌溉之餘水多以迴歸水形式，出現於下游地區重覆利用，上游處產生之餘水可由橫向水路直接攔截直接引入下游田區灌溉或匯流至埤塘等蓄水設施或河川，再取水灌溉下游灌區，而由應用層面而言，經重複灌溉使用後，無法再提供其他標的使用者為灌區內的農地迴歸水，亦屬於傳統之補助水源。然於探討地表迴歸水之同時，其補注於地下水之動態，亦應同時加以關注，俾了解竹桃北地區在抗旱時期，是否能以地下水作為偏遠地區之補助水源，以度過水情不佳的枯水期。 ;In Taiwan, due to the improvement of living standards, urbanization, industrial parks and high-tech science parks continued to increase, livelihoods and industrial water consumption increased, people's livelihood and industrial water use shifted from agricultural water use increasingly. Although irrigation has the merit of having a high flexibility of enduring water scarcity, it is also necessary to adjust the water use in a relatively modest manner to increase the water requirement elasticity during periods of water shortage. The topography of Taoyuan platform is taken as an example. In the case of irrigation, the remaining water is mostly in the form of return water, which appears in the lower reaches of the area for reuse. The surplus water generated in the upstream can be intercepted directly by the horizontal waterway to the downstream fields into irrigation facilities or confluence with ponds and other water storage facilities or rivers and re-drawing of irrigation water for downstream irrigation areas. However, from the aspect of application, after repeated irrigation, return water can provide no other target users for farmland in irrigation areas. Moreover, when we are investigating the return of surface water, we should pay attention to the dynamics of groundwater during its replenishment so as to understand whether the northern part of the Taiwan can use groundwater as a subsidized water source in remote areas during the drought-stricken period. This study focuses on the development of farm pond and groundwater intelligent drought management scheme as a drought backup supply system to provide relevant water management units reference to improve the efficiency of irrigation water use in the agricultural sector and make full use of the pond and groundwater water resources as well.
