摘  要:
为了探究坎儿井衰减与地下水补排系统响应关系,利用地下水位观测资料和坎儿井流量监测资料,结合鄯善县历次地下水资源调查评价资料和坎儿井统计数据,分析了地下水补给量、排泄量对坎儿井衰减的影响,并建立了最小二乘回归模型,在执行最严格水资源管理制度下对2020年、2030年坎儿井出水量进行了预测。结果表明,坎儿井流量动态与地下水位动态基本同步;北盆地的坎儿井出水量主要受地下水补给量的影响,南盆地主要受地下水开采量的影响。地下水开采量是影响鄯善县坎儿井衰减的关键因素,在最严格水资源管理制度下鄯善县坎儿井出水量将会在2020年恢复至0.83亿m~3,2030年恢复至0.87亿m~3。

摘  要:
In order to explore the corresponding relationship between Karez decreasing and groundwater recharge and discharge system,groundwater level observation data and Karez water discharge monitoring data were used to analyze the effects of groundwater recharge and excretion on Karez number decreasing combined with previous evaluation data of Shanshan groundwater resource and Karez statistical data.In addition,a least-squares regression model was established to forecast 2020 and 2030annual Karez water discharge in the implementation of the most stringent water management system.The results indicated that Karez discharge and groundwater level had the same dynamic.Karez water discharge in the north basin was mainly contributed to groundwater recharge,while in the south basin it was mainly affected by groundwater extraction.For the entire Shanshan County,groundwater extraction was a key factor.Karez water discharge would be restored to 0.83×108 m~3 in 2020 and 0.87×108 m~3 in 2030 under the most stringent water resources management system.
