This study review the water resources of Kaoping Hsi Basin and Pingtung Plain, author get the following result beside to expound water balance, landsubsidence, seawater intrusion, ground water recharge etc. 1.The maximum amount of water resources of Kaoping Hsi Basin is about 7.9 billion m3 a year, and its 60% come from Laonung His. Pingtung Plain collect three main river discharge of Kaoping Hsi, TungKang His and Linpien His, the total maximum amount of water resources is about 9.5 billion m3 a year, and its 75% concentrate in June to September. 2.The monthly average discharge shows TungKang Hsi is belong to gaining stream, and Linpien Hsi is belong stream. 3.Three main river have serious seawater pollution near the estuary owing to tidal river and drainage saltwater of fish breeding ponds. TungKang His and lower part of Kaoping Hsi also have serious pollution by the polluted water of livestock rising and domestic use. 4.For resonable water resources management of Kaoping Area, it is need to serious consider those ヾ To construct large reservoir to storage the water of plentipul discharge period, ゝ Without withdraw the groundwater at rainfall season and construct check dams to increase water recharge and ゞ To collect groundwater taxes for promoting the effective groundwater use.
