为深入了解岩溶地区不同水源转化机理,文章以Basic Hydrology System为平台设计了4组小尺度物理试验.分别对裸露型岩溶区裂隙管道地下径流衰减规律,覆盖型岩溶区土壤达西流、裂隙管道水流转化规律,地表径流、土壤达西流、裂隙管道地下径流三者在覆盖型岩溶区和不同覆盖厚度条件下的转化关系进行了物理模拟.通过试验数据并结合指数衰减方程,得到了裸露型岩溶区流量衰减系数与降雨强度的关系;覆盖型岩溶区以及不同覆盖厚度条件下PSSK(precipitation-surface water-soil water-karst water,降水-地表水-土壤水-岩溶水)转化规律.

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.
