Karst water prospecting and emergency drought relief demonstration project in Jibi area on the edge of Luxi basin，Yunnan Province

Jibi is located on the lower edge of Luxi basin，with poor uniformity of karst development，and serious surface drought and water shortage，so it is difficult to find water by drilling wells. In this paper，we discusses the hydrogeological conditions， and the distribution and occurrence characteristics of groundwater in Jibi area，and introduces the working method of groundwater prospecting and well layout in karst area. The well location is determined by using high density resistivity method，IP sounding ，combined with hydrogeological survey results，and the result shows the borehole has abundant water. The analysis shows that the difference of water abundance of karst aquifer is mainly controlled by the filling of karst fissures and the connectivity of karst aquifers. Finally， we summarizes and put forward a set of emergency drought relief models based on the development and utilization of karst water as the main leader，combining drought resistance with water-saving sprinkler and high efficiency agricultural development，with significant economic benefits. We also put forward the suggestion on management measures for prospecting and utilization of groundwater.
