Due to the better quality of groundwater resources, the agriculture with the flourishing development in various industries has boomed since the retrocession of Taiwan. A large amount of groundwater resources has been used and become important issues to water resources development in Pingtung Plain. There are several reasons affecting groundwater resources in Pingtung Plain, particularly the recharge area has been reduced due to land development and construction that lead to shrunk number of rivers, preventing groundwater to be recharged with the maximum amount on a surface runoff to river. The annual volume of groundwater recharged to the middle fan has been extracted to use by agricultural irrigation and inland freshwater aquaculture farming, while the recharge water amount flowing into the distal fan is reduced. The result of heavily centralized groundwater extraction by the coastal aquaculture use was then the serious land subsidence occurred at the distal fan region.

The thesis was provided subsequent references for personnel working with groundwater resources with full integration of history and data that the Government and the public can understand the changes of groundwater for agricultural use in the plain. The thesis was to estimate the annually required depth of groundwater for farmed fish or shrimp species, i.e. freshwater shrimp annual water requirement of 142,240 m3/ha, eels annual water requirement of 398,700 m3/ha, other freshwater fish requirement 89,400 m3/ha in average, and grouper and other seawater fish annual requirement 152,940 m3/ha in average and seawater shrimp annual water requirement of 164,420 m3/ha. For Taiwan Sugar Corporation, annual depth of 18,600 m3/ha during the sugarcane growing stage in autumn time, whereas the annual demand for water is 17,200 m3/ha for the spring time and the perennial root requires 19,100 m3/ha in annual.
