【摘要】 <正> 七十年代以来,不少学者注意到岩溶水系统中存在快速流(D.I.Smith,T.C.Atkinson.H.Paloc,C.Droque,D.C.Ford,V.Yevjevich,P.W.williem),并进行了定量分析和专门性的研究。于浩然等在水文地质研究总结中也提过类似的问题。岩溶水系统中快速流与慢速流是相对而言,不同系统间岩溶水流速差别很大,难以规定统一的快速流值域。一般地说,快速流赋存于溶洞、管道或岩溶发育的裂隙网络介质中,它是流速较快,对降水反应敏感的集中性水流。研究快速流的特征,将有助于揭示复杂的岩溶地下水系统的规律性,更好地开发利用岩溶水资源。更多还原

【Abstract】 Two types of karst water-bearing media commonly can be recognized in China, i,e., fissure-corroded fissure and cavern-conduit systems, which can either occur individually or simultaneously forming various combinations of karst media. These heterogeneous water-bearing media as the main facter govern the occurrence and movement of karst groundwater.Rapid flow of karst groundwater system is usually present in two categories of groundwater flow as follows:( 1 ) Concentrated subsurface seepage flow occurring in karst developed zone of fissure-corroded fissure medium system.( 2 ) Subsurface stream ( or conduit flow) occurring in cavern-conduit medium system.As regards karst groundwater system in China, only concentrated subsurface seepage flow appears in north China, whereas in the south both types exist. This is because of the difference between the northern and southern part of China in geological setting.Through the study of two typical cases of rapid flow-Heilongdong karst spring group in north China and Luota subterranean stream system in south China, it is shown that the response of the rapid flow in concentrated seepage flow zone to rainfall pulse is slower and the discharge is relatively stable, however, the response for that of subterranean stream type is often very rapid,and the discharge varies greatly. The fact is shown that karst grcundwater systems with different structure possess different capability of regulation.更多还原
