 **Contents(報告內容):**  
 Preface 前言  
 1. Live with water 與水共生  
 2. New use for old wisdom-underground river weirs 舊技術新思維  
 3.From Crisis to turning point: groundwater resources 地下水-不濁的救命水  
 4. Artificial Recharge of Groundwater in High-Infiltration Basins at PingtungPlain, Taiwan大潮洲地下水人工補注湖計畫  
 5.Groundwater ecology 地下水生態學

 民國94年7月海棠颱風後高屏堰橡皮壩及上、下游被泥砂淹沒情形Rob dam immerged by settled fine material after typhoon on July, 2005  
   
 “安全用水是人類最根本的需要，因此也是最基本的人權飲用受到污染的水不但危及人類社會健康，更是對人性尊嚴的一種侮辱”  
 聯合國秘書長科菲•安南  
 “Access to safe water is a fundamental human need and, therefore, a basic human right.Contaminated water jeopardizes both the physical and social health of all people. It is an affront to human dignity.”  
 KofiAnnan, United Nations Secretary-General  
   
 **堰體工程(Subsurface dam)**  
   
 •水源特性–旱季伏流水分佈於B點溪水沉降至河床，在B及C點間地下水位面梯度為1/63及1/100，C點下游之地下水位則漸深入河床下及沖積扇中，E之地下水位面極為平緩，於G點附近與地形面相切，形成湧泉–枯水期伏流水流速為1.21cm/sec (1,045m/day)  
   
 •地下堰址實際深度–由常流點A上游900m處，以1/63坡度至堰址處7.1m–河床下2.7m~9.1m–原設計為河床下25m ，與實際相差甚大，因氣象因素及當時工程技術所致  
   
 **伏流水方案**  
   
 集水廊道  
 集水廊道是使用有孔管渠水平或傾斜埋設於含水層中，汲取伏流水或淺層地下水之設施。  
   
 大型集水管  
 利用透水管之集排能力強及耐高壓質量輕施工容易特性，予以汲取伏流水。  
 寬口井結合輻射井  
   
 輻射井是由大口徑透水性集水管和寬口井內沿高灘地方向佈設的多根輻射管﹙滲透管﹚組成。  
   
 **虛擬水資源(Virtual Water)的定義Water)**  
 (Virtual WaterVirtual WaterThe water that is used in the production process of an agricultuThe agricultural ral or industrial product is called the 'virtual water' contained inor inthe the productproduct…………(Tony Allan, 1997)(1997)  
   
 ◎泛指糧食作物在製造生產過程中所消耗—但消費者在食用時並未真正喝到的水量。  
 ◎ 國家以貿易的形式出口產品，則實際上是以 虛擬  
 的形式出口「水資源」 。  
 ◎ 缺水地區可以貿易的方式購買耗水度高的農產品  
 來達到水和糧食的安全。  
   
 **結果與討論**  
 ‧適合屏東平原內陸大宗水產養殖優劣次序  
 鱉、石斑＞低耗水性，高獲利價值水產，可以鼓勵在屏東平原養殖，進而作為區域外虛擬水量出口種類  
 鰻魚、吳郭魚＞低耗水性，但相對獲利價值並不高，應該朝向精緻化養殖，透過食品加工提高附加價值  
 淡水蝦、鹹水蝦＞高耗水性，獲利價值亦高的水產品，不予鼓勵大宗養殖而宜以進口的方式代替，並應該投入節水性技術的研究  
 虱目魚、鯛魚＞高耗水性，也相對低獲利價值的水產，不鼓勵在屏東平原養殖，而應該藉由區域外進口的方式供應。
