沙雅县地处极度的干旱区,农业为灌溉农业,受河流来水季节性不均匀的制约及塔河综合治理要求,灌区农业生产主要存在水土资源不平衡、水量供需紧张问题。为提高灌区供水保证率,对沙雅县水源地进行水文地质勘查,通过已有成果、机井钻孔资料及本次46组抽水试验,分析区域地下水的补径排条件,得到项目区含水层富水性分布。结果表明:北部富水性较好,东、西两侧及南部富水性较差,本次机井大部分布置在地下水开采条件较好的项目区北部。
Shaya County is located in the arid arid area. Agriculture is irrigated agriculture. Due to the seasonal uneven incoming water flow and the comprehensive treatment of Tahe River, the imbalanced water and land resources and the shortage of water supply and demand mainly exist in the irrigated area. In order to improve the water supply guarantee rate in the irrigated area, hydrogeological survey was conducted on the water source areas in Shaya County. Based on the existing achievements, borehole drilling data and the 46 pumping tests, the recharge conditions of groundwater in the project area were analyzed. Waterborne distribution. The results show that the water-rich in the north is better, the water-rich in the east and west sides and the south are poor, and most of the wells are arranged in the northern part of the project area where the exploitation of groundwater is good.
