Freshwater lens is the freshwater resource under ground on a coral island. It's formation , characterstic and influence factors were discussed. A mathematics model was used to simulate the change of the lens properly. The coordinates of the boundary between freshwater and saline water from the model were in very good agrement with the field observaions. Based on the results from the simulation, the yield and pumping rate can be determined . The prnper development methods given in this paper are very valuable in engineering.
