| 摘 要： | In order to analyze the condition of special landform and regularity of special hydrological movement inkarst area, the method of Geomorphologic Instantaneous Unit Hydrograph (GIUH) has been used to divide the river net-works into three grades in the research area and the karst hydrologic processes were simulated with Nash instantaneous u-nit hydrograph(NIUH). The combination of the GIUH and NIUH fully considers the moving path of water particles indrainage and the regional composition of runoff at the end of the drainage, resulting in a rational combination of probabili-ty of GIUH and NIUH and geomorphologic parameters which could reflect the complexity of the landform structure ofkarst drainage. The results showed that the combined method of GIUH and NIUH has clear physical concept and accept-able precision, which can be widely applied on hydrological studies of karst area.

| Abstract: | In order to analyze the condition of special landform and regularity of special hydrological movement in karst area, the method
of Geomorphologic Instantaneous Unit Hydrograph (GIUH) has been used to divide the river networks into three grades in the
research area and the karst hydrologic processes were simulated with Nash instantaneous unit hydrography(NIUH). The combination
of the GIUH and NIUH fully considers the moving path of water particles in drainage and the regional composition of runoff
at the end of the drainage, resulting in a rational combination of probability of GIUH and NIUH and geomorphologic parameters
which could reflect the complexity of the landform structure of karst drainage. The results showed that the combined method
of GIUH and NIUH has clear physical concept and acceptable precision, which can be widely applied on hydrological studies
of karst area.
