Abstract This paper is based on the results of geological survey project “Northern Karst Hydrogeological and Environment Geological Survey Demonstration”. The project choose Yuquanshan springshed, Heilongguan springshed and Yugudong springshed as working areas. Different techniques and methods are adopted in field survey, such as ground survey, remote sensing interpretation, geophysical prospecting, hydrogeological drilling, tracer test, water balance station observation, water chemistry and isotope method (δD, δ18O, C, δ34S and Sr), and a large number of first-hand data are obtained. Comprehensive study of the data(including the former data), the project makes such main progress: firstly, find out the Karst hydrogeological conditions and environmental problems about the working area and divide it into two aquifers, three Karst water systems and five sub systems; secondly, through carrying out equilibrium observation in the Heilongguan springshed, the precipitation infiltration coefficient is obtained in the carbonate exposed area of the Cambrian-Ordovician and Jixian system, and we evaluate the natural water resources and recoverable water resources by using the latest data; thirdly, we propose measures of the Karst water conservation and environmental governance from three aspects of policy, technology and engineering for outstanding Karst water environmental problems (including potential problems).
