摘　　要：岩溶地下河系统水流运动多受控于岩溶多重介质环境,其主干空间展布、水体贮存、水流运动、水循环等规律的变化具多因多果性。在中国南方岩溶区岩溶地下河系统物质和能量转换的基础上,分析了其形成和演化等相关条件,研究和总结了其水流运动方向的多重性、速度的多变性、地表地下方式的转化性、时空配置的多样性及水流运动演变规律;根据维数、压力、流态等不同原则,将中国南方岩溶地下河系统水流运动方式进行分类。结合中国南方岩溶地下河系统研究现状,提出今后需加强与实践的重点。The underground river system flow movement in karst region is mostly subjected to karst multi-medium environment.The change of space distribution,watery storage,water flow and cycle shows the characteristics of multi-factor and multi-result.Based on the research of material transfer and energy transformation in underground river system in karst region of south China,the correlated condition in the process of formation and evolution is analyzed,including the multiplicity of water flow movement direction,polytrope of water velocity,convertibility of surface and underground water,diversity of spatio-temporal distribution and the evolution regularity of water flow movement.According to different principles such as dimension,pressure and flow state,water flow modes are categorized in underground river system in karst region of south China.Some ideas for future research are provided.
