摘　　要：屏东平原为台湾地区屏东县的精华 ,也是台湾南部地区最重要的地下水库。其范围北起阿里山脉末端 ,东至中央山脉潮州断层 ,南以台湾海峡为界 ,西达领口丘陵 ,南北长约 50 km ,东西宽约2 0 km,面积计 1130 km2。该区域内主要河川计有高屏溪、东港溪及林边溪等三条河川 ,联合其他次要河川 ,纵横交流 ,形成一连串的冲积扇群 ,成为地下水补给良好之地下含水层。近年来 ,由于该地区各项开发迅速 ,用水遽增 ,特别是大量使用地下水之农业和养殖业。为因应目前及未来之用水需求 ,除了目前正兴建的南化水库加高工程外 ,水资源局依照台湾南部地区水资源综合发展计划 ,拟开发美浓和玛家水库 ,以及于高平溪设立 5座拦河堰。此种种水利建构措施 ,均朝屏东地区之地下水合理经营及永续发展为首要考量。此外 ,地下水观测网于屏东地区业已建构完毕 ,其中包含 51站水文地质调查站 ,12 7口地下水监测井 ,2 3口抽水试验井 ,9口地层下陷监测井。随着屏东地区地下水观测网建立完成后 ,日后针对地下水利用及营运管理 ,将着重于资料的整合与分析 ,期能建立最佳的地下水营运管理模式。Pingtung Plain is the essence of Pingtung County,Taiwan.Itranges north from the A- Li Mountain south to the Taiwan Strait,and east from the Chao- Chou Fault of the Central Mountains west to the Lin- Ko Terrains.It is50 kilometers in length and2 0 kilometers in width,which has the area of 1 1 3 5km2 .Within this area,three primary rivers,Kao- Ping Riv- er,Tung- Kang River,and Lin- Pien River,meander with other secondary and ordinary rivers which due to geological characteristic result in the continuous formation of alluvial fans and a huge groundwater aquifer.Owing to the huge population and the development of the agricul- ture and industries,the water consumption in this area increases enormously,which has ex- ceeded the water supply from the distribution systems.In order to provide sufficientwatersup- ply,the renovation of Nan- Hua Dam has been undertaken to increase its storage capacity and to provide more waterfor domestic uses.According to the projectof Integrated DevelopmentofWater Resources in the southern Taiwan,the Mei- Nung,Ma- Chia Dams as well as five low dams in Kao- Ping River are also scheduled for construction in the nearfuture.All these efforts are to ensure sufficient water supply and the sustainable development of groundwater in Ping- tung Plain.Additionally,the establishment of groundwater monitoring network in Pingtung Plain has been completed in 1 998,which includes51 hydrogeological survey stations,1 2 7 groundwater monitoring wells,2 3 pumping testwells,and 9land subsidence monitoring wells. As the completion of the groundwater monitoring wells,future tasks regarding groundwater u- tilization and management will concentrate on the integration and analysis of collected ground- water information,from which,hopefully,the best maneuver on groundwater operation and management may be established.
