摘　　要：为了实现吐鲁番盆地坎儿井冬闲水资源的有效利用,同时回补区域地下水,亟需建设地下水回灌工程,并确定合理的工程建设位置及有效的回灌方式。首先基于坎儿井流量、回灌水源距离、含水层渗透系数、地下水埋深、机井密度及地形坡度6项指标构建地下水回灌适宜性评价体系,利用ArcGIS空间分析功能进行地下水回灌适宜性区划,并在典型回灌适宜区开展现场试验确定地下水回灌方式。结果表明,高昌区中部、鄯善县北盆地灌区及托克逊县东北部部分区域具有丰富的回灌水源及储水空间,整体渗透系数均大于15 m/d,适宜开展坎儿井冬闲水回灌;利用机电井回灌的井灌方式,能实现对地下水的有效回补,适用于研究区坎儿井冬闲水回灌。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.
