In particular, for arid regions, water is the main factor that limits regional development. However, Water amount from the Yellow River is decreasing in Hetao Irrigation District of Inner Mongolia (China), which will be limited to 4.0 × 10⁹ m³/a by the State Department of China in the future. Therefore, to establish a numerical simulation model for the groundwater dynamics and to utilize the limited water resources in this region have become an urgent problem that needs to be solved. Based on the field observed data from 1981 to 2000, the groundwater numerical simulation model was established in this paper, and the changes of groundwater level in irrigated area were analyzed under different irrigation water and groundwater exploitation before and after water saving reconstruction. Finally, the reasonable exploitation of groundwater was calculated according to the simulated results. The research results have the important signification to the sustainable development of irrigation district, which can also provide the valuable reference for conjunctive use of surface and ground water.
