In order to realize the effective utilization of winter idle water resources in kariz of Turpan Basin and recharge the regional groundwater, it is urgent to carry out groundwater recharge project in this area and determine the reasonable construction location and effective recharge mode. Firstly, the suitability evaluation system of groundwater recharge was constructed based on the six indexes of kariz flow, recharge source distance, aquifer permeability coefficient, groundwater depth, electromechanical well density and terrain slope. The suitability zoning of groundwater recharge was carried out by using ArcGIS spatial analysis function. Field tests were carried out in the typical recharge suitable areas to study groundwater recharge methods. The results show that there are abundant recharge water sources and storage space in the middle of Gaochang District, the north basin irrigation area of Shanshan County and the northeast part of Toksun County. The overall permeability coefficient is greater than 15m/d, which is suitable for the recharge of kariz winter leisure water. The effective recharge of groundwater can be realized by using the well irrigation method of the electromechanical well recharge, which is suitable for the recharge of the winter idle water in the study area.
