We present a discussion of the state-of-the art on modelling geometrical characteristics, hydrogeological behavior and geochemical evolution of karst aquifers of meteoric origin. The considered key karst processes include: (1) the recharge processes, (2) the various hydrodynamic processes in the vadose and phreatic zones, (3) the related transport processes and (4) the speleogenesis processes. Different types of approaches for modelling geometrical characteristics of karst conduit networks are summarized. Integrated numerical studies on hydrogeological behavior of karst aquifers with functional and physically based models are then reviewed. Challenging issues in karst modelling are further discussed based on previous modelling progresses. The paper finally offers recommendations for advancing the modelling of hydrogeological behavior of karst systems and lists several open questions for future research.

我们讨论了对气象起源的岩溶含水层的几何特征、水文地质行为和地球化学演化进行建模的最新技术。所考虑的关键喀斯特过程包括：（1）补给过程，（2）渗流区和潜水区的各种水动力过程，（3）相关的运输过程和（4）洞穴形成过程。总结了模拟岩溶管道网络几何特征的不同类型的方法。然后回顾了基于功能和物理模型的岩溶含水层水文地质行为的综合数值研究。基于以往的建模进展，进一步讨论了岩溶建模中的挑战性问题。
