    Abstract
  • The 10,000 years evolution of fractured karst system,which has precipitation infiltration and river recharge,is calculated using finite difference method, cubic law and Dreybort's (1996) empirical formula after building on the conceptual model of fractured karst system The result shows that the dissolution of karst aquifer system mainly occurs in the point of precipitation infiltration, recharge rivers and karst springs. With the dissolution of the karst aquifer system, the water tables were declining and some of the karst springs were dry. We found that the number of precipitation infiltration does not significantly affect the evolution of fractured karst system which has river recharge.
