摘　　要：为合理区分多地层结构区域的地下水和咸水的供水量,以新疆伽师县为例,在构建三维地层结构模型,收集机电井位置、井深、供水量,以及典型机电井矿化度检测的基础上,按照机电井分层统计、逐层矿化度分区图绘制、机电井与矿化度分区图逐层叠加的方法,统计出各地层的地下水(矿化度M≤2 g/L)和咸水(M>2 g/L)的供水量。结果表明:伽师县2021年地下水(矿化度M≤2 g/L)供水量为4.13亿m 3,咸水(M>2 g/L)供水量为6.55亿m 3。本次研究提出的多地层结构统计地下水(矿化度M≤2 g/L)和咸水(M>2 g/L)供水量的具体分析方法,具有较高的操作性,可为今后类似区域合理统计地下水(矿化度M≤2 g/L)和咸水(M>2 g/L)供水量提供重要参考。In order to reasonably distinguish the water supply of groundwater(salinity M≤2 g/L)and brackish water(M>2 g/L)in the multi-stratigraphic structure area,taking Jiash County in Xinjiang as an example,a three-dimensional stratigraphic structure model is constructed,combined with basic information such as the location,depth and water supply of electro-mechanical wells as well as the detection of the salinity of typical electromechanical wells,the water supply of groundwater(salinity M≤2 g/L)and saline water(M>2 g/L)in each stratum is calculated according to the methods of layered statistics of electromechanical wells,stratum-by-stratum salinity zoning map drawing,and stratum-by-stratum superposition of electromechanical wells and salinity zoning maps.The results show that that the water supply of groundwater(salinity M≤2 g/L)and the water supply of brackish water(M>2 g/L)in Jiashi County in 2021 is 413 million m 3,and the water supply of salt water(M>2 g/L)is 655 million m 3.The specific analysis method of groundwater(salinity M≤2 g/L)and saltwater(M>2 g/L)water supply proposed in this study has high operability and can provide an important reference for the reasonable water supply statistics of groundwater(salinity M≤2 g/L)and brackish water(M>2 g/L)in similar areas in the future.
