摘要
水文地质概念模型是地下水模拟与水资源评价的基础。为了构建地下水数值模拟模型,以鄂尔多斯白垩系地下水盆地为研究对象,以丰富翔实的勘查资料为依据,从白垩系地下水系统边界条件、水文地质结构、水流系统、水文地质参数、源汇项等方面进行概化,联合采用ArcGIS、RS、GMS、同位素、基流分割、地质统计学、随机模拟等技术方法,建立了一组水文地质概念模型及其相应的空间离散表达,并讨论了地下水模拟面临的问题与发展趋势。
A hydrogeological conceptual model is the basis of groundwater numerical modeling and groundwater resource assessments. A conceptual model of the Cretaceous groundwater basin was developed through analysis of the boundary conditions, hydrological structure, flow systems, hydrological parameters and sources and sinks. The sources and sinks of the groundwater balance and the hydraulic conductivity model were calculated using ArcGIS, RS, GMS, isotopes, base flow separation, geostatistics and stochastic modeling. The conceptual model and its corresponding mathematical expressions were developed and problems facing groundwater modeling and its development trend were discussed.
