摘　　要：阐述岩溶地下水运动特点，分别讨论南方岩溶地下水与北方岩溶地下水运动特征，在此基础上建立了概念性模型。论述岩溶地下水运动的若干计算方法、着重讨论了数值方法、系统分析方法及随机方法等的适用条件及计算精度，同时介绍了一些以往文献没有提及的水文地质现象。认为，应根据具体的岩溶地下水运动特点，选用相应的计算方法，使成果更符合实际。In this paper the character istics of karst water flow are expounded and the features of karst water movement in South China and in North China are discussed respectively.Based on those characteristics,conceptual models are established and several calculation methods for karst water flow are expounded.The conditions of application and the accuracy of calculation of numerical computation,system analysis and stochastic method are emphatically discussed.Some hydrogeological phenomena which have not been mentioned so far are discussed also.The results will coincide with the actual situation if a suitable calculation method is chosen according to the specific characteristics of karst water flow.
