Abstract During the 1:50 000 hydrogeology and environmental geology survey of Jiumo, Dongbao, Majie and Nasajie in Guangnan area, Yunnan province, the regional hydrogeology conditions are found out, the groundwater system are divided and water resources are evaluated. The main water-rich areas are ascertained according to water resources distribution and tectonic conditions, and the groundwater zone is divided by basin unit in the working area. Integrated exploration and developing well construction and underground river development has notable effect on local drought resistance service, and the model of emergency drought resistance, water searching and well drilling is summarized.Drought and rocky desertification have been ascertained as main environmental geological problems in the working area. These provide basis for rational exploitation and utilization of groundwater resources, and comprehensive treatment of geological environment in Karst region of southwest China.
