Abstract: Changes in the pattern of the development and utilization of water resources will lead to the changes in the recharge and discharge properties of groundwater. This article analyses the data interaction between water resources optimal allocation model and groundwater mathematical simulation model, and these models are combined to calculate the exploitable quantity of groundwater, applied in Shanshan County, Xinjiang Uygur Autonomous Region. With the changes of planning optimized allocation, development and utilization of water resources, the calculation results show that exploitation and overexploitation of groundwater can be respectively decreased from 235 million m 3 and 186 million m 3 in present to 137 million m 3 and 0 million m 3 in 2030 year. This article solves the problem of accurate quantification for the amount of available groundwater successfully, and it also can be used as the basis for the utilization and protection of groundwater resources.

Key words: exploitable quantity of groundwater, water resources optimal allocation model, groundwater mathematical simulation model, coupling iteration
