复杂岩溶介质地下水模拟研究进展

Recent advances in simulation approaches of the complex karst medium

由于岩溶发育的不连续性、非均匀性和各向异性,其导水性在空间上存在巨大差异,给岩溶地下水流模拟带来了挑战。综述了岩溶地下水数值模拟、黑箱模拟和随机模拟3种模拟方法的研究进展,阐述了各类建模方法的思想、概念模型、适用条件,分析论述了各类方法的优势及不足。结合建模和应用,指出今后应加强岩溶发育规律、赋存于不同介质形态中水流的相互作用机理、基于多模型的岩溶水系统的整体模拟和多方法综合研究。

Due to the heterogeneity and anisotropy nature,the karst medium is recognized very complicated.The discontinuous karst aquifers pose a major challenge for hydrogeological investigations and simulations. In this paper,research progress on karst groundwater simulation is reviewed from the points of view of numerical simulation,stochastic simulation and black-box simulation. The principle of all kinds of modeling methods,concept models,application conditions are expounded,the advantages and limitations of each approach and the principles that guide the choice of modelling approaches are discussed. The author points out that groundwater flow mechanism in karst media, multi-model based surface water-subsurface water holistic simulation and comprehensive research methods should be strengthen in the future research.
