西北灌区地下水资源开发利用研究进展及发展趋势

Recent Progress in the Development and Utilization of Groundwater Resources in Northwestern Irrigation Districts

围绕西北灌区地下水资源开发利用面临的问题,分析了灌区地下水的基本特征及调蓄功能,重新审视了合理开发利用地下水资源对灌区可持续发展的重要支撑作用。在此基础上,从变化环境下西北灌区地下水循环与演化机制、灌区地表水与地下水联合调控、灌区地下水开采模式及机井合理布局、灌区地下水管理机制4个方面归纳分析了国内外研究现状及进展,针对西北灌区地下水资源开发利用研究中存在的关键科学问题,探讨了灌区地下水资源开发利用科学与技术研究发展的趋势。

Recent progresses in the development and utilization of groundwater resources in northwestern irrigation districts were summarized in this paper.Groundwater is very important to the sustainable development of northwestern irrigation districts,therefore the basic characteristics and its regulation and storage effects was analyzed firstly,which is very helpful to realize its rational development and utilization.Then the following issues were discussed in detail,which are groundwater dynamics,its evolution mechanism,conjunctive use and management with surface water,development strategy and pumping well layout optimization,management system.Finally,several important future research questions were proposed.
