摘要
以秦王川盆地跨流域引水灌溉为例,建立地下水响应的水动力学模拟模型,分析不同水资源开发利用情景对当地地下水系统的影响。以三角形单元进行网格划分,用有限元法进行求解,给出了不同引水和灌溉方案下,长期运行的地下水响应和对土地利用的影响,为秦王川盆地开发利用提供了依据。
Taking the irrigation with trans-basin water diversion for Qinwangchuan Basin in Gansu Province as the studying case, a hydrodynamic model for simulation of the response from groundwater therein is established herein, and then the effects from different developing prospects on the local groundwater are analyzed. The effects from the response of the groundwater during longterm operation of the irrigation on the land utilization under different water diversion and irrigation schemes are given by mesh division made with triangular elements and the solution given by the finit element method; which provide a basis for the development and utilization of Qinwangchuan Basin.
