地下水数值模型在中国的应用现状及发展趋势

地下水数值模型在地下水资源定量评价及相关领域研究中得到了广泛的应用。本文介绍了几种流行的数值模拟模型,阐述了模型特点及其在我国的应用现状。指出模型对客观实体概化存在误差,模拟精度有待于提高;裂隙介质、岩溶介质中的地下水运移模拟技术未解决,限制了模型应用范围;强调了模型数据前后处理能力的不足;指出了模拟技术在地下水源汇项概化、地下水运动机理方面的发展前景,提出多种模型耦合以及与GIS紧密结合的重要性,并指出由于使用对象的转变给地下水模型发展带来的新机遇。

Current practice and development trend in numerical modeling of groundwater in China

Numerical models of groundwater were applied widely for quantitative evaluation of groundwater resources and in relevant research fields.Features and current situation of application of several popular numerical models in China were introduced in this paper.The shortcomings in terms of modeling precision,application extension and ability of pre-and-post data processing were analyzed.The importance of studying groundwater flow mechanism in crevice medium and karst medium,coupling of different models and combining of models with GIS was emphasized.Finally,it is pointed out that groundwater models will face new challenges with changes of users.
