///For investigation of different water source transformation mechanism in karst areas, four small-scale experiments were designed on the basis of Basic Hydrology System. Using this model, the followings were simulated: 1) the water dynamics process in an uncovered karst area; 2) soil Darcy flow, karst fissure and conduit flow transform regularity in a karst area with covered layers; 3) PSSK(Precipitation-Soil water-Surface water-Karst water) transform regularity in karst areas with covered layer; and 4) PSSK transform regularity in karst areas with different heights of covered layer. After analyzing the experiment data combined with exponent attenuation equation, the followings were gained: 1) the relationship between spring flow attenuation coefficient and rainfall intensity; 2) the relationship between component of each sub dynamic and rainfall intensity; 3) PSSK transform regularity in karst areas with covered layer; and 4) PSSK transform regularity in karst areas with different heights of covered layer. The rationality of exponent attenuation equation was also verified by water level observation experiments.
