【 摘 要 】

Karst development has an important impact on regional groundwater movement. Based on the tracer test, this paper analyzes the development of groundwater karst in the Dawu water source. The results show that: 1) The main groundwater flow direction of the Wangzhai experimental area is northeast and southeast, and the velocity of groundwater flow is 110.37∼420m/d; the groundwater mainstream direction of the Hougao test area is northward and eastward, and the velocity of groundwater flow is 9.09∼289.5m/d. 2) The karst development of the aquifer in the study area is multilayered, and solution opening, solution crack, fracture, pipelines coexist. The Wangzhai study area has a hydraulic connection with the downstream Liuzheng water source, it is not recommended to develop industries with heavy groundwater pollution.
