摘要
在简要介绍研究区水文地质条件的基础上,初步选定了7个地下水集中扩采方案,建立了研究区地下水渗流数学模型,对各扩采方案开采后地下水流场的变化,浅层水和深层水补排关系的改变以及开采水质进行了对比研究,推荐方案7为最优开采方案。这一结论对喀什市地下水的合理开发具有重要的指导意义。
Kashgar City is one of the important cities in south Xinjiang, and groundwater is the main water source of the industrial and agricultural production and drinking water. Some long-term and irreversible impacts on the environmental may be resulted in by the irrational exploitation of groundwater resources in such arid area due to the arid climate and the peculiar hydrogeologic conditions. Therefore, it is of significance to research the exploitation schemes of groundwater beneath Kashgar City. In this paper, the hydrogeologic conditions in the study area, Kashgar City, Xinjiang Uygur Autonomous Region, are briefly introduced, 7 groundwater exploitation fields are preliminarily delimited, and the vadose mathematical models of groundwater beneath Kashgar City are developed. The change of groundwater current and the relationship between the shallow groundwater and deep groundwater after the groundwater is pumped as well as the groundwater quality are compared and researched. The groundwater exploitation scheme 7 is recommended. The conclusions are of significance for the rational exploitation of groundwater beneath Kashgar City.
