内蒙古巴彦浩特水源地地下水取水可行性研究

Feasibility of groundwater extraction in water source region of Bayanhaote in Inner Mongolia

巴彦浩特是阿拉善盟的政治、经济、文化、交通中心,随着城市建设的快速发展和人口剧增,供水能力严重不足成为该地区城镇化发展、经济振兴的制约因素,开发水源地势在必行。文中以发展巴彦浩特水源地水资源评价为依托,利用开采系数法、抽水试验法、水位恢复法和数值模型模拟等,对地下水取水的可靠性、可行性及影响等方面进行了评价。评价结果表明,水源地的地下水可开采量为541.858万m3/a,取水可靠,取水井布置合理,取水方案可行,取水后不会对区域地下水环境造成影响。研究的分析方法和成果可为类似评价研究和工程应用提供借鉴与参考。

Bayanhaote is the political,economic,cultural,transportation center of the Alashanmeng. With the rapid development of city construction and population growth,a serious shortage of the water supply capacity has become the restrictive factors for urbanization development and economic revitalization in this region,so the government must develop the water sources. In this research,based on the subject of the evaluation of water sources in Bayanhaote,the mining coefficient method,the pumping test,the water level recovery method and the numerical simulation method were used to evaluate the reliability,feasibility and the water abstraction impact of groundwater resources. The evaluation results show that the available groundwater resources is 5,418,580 m3/ a,the quantity of water is reliable,the arrangement of the wells position is reasonable,the water abstraction scheme is feasible and there will be no impact on the regional groundwater environment. Analytical methods and test results can provide reference for the similar experimental research and engineering applications.
