Estimating groundwater recharge in Jinci karst groundwater system, North China

More than 25% of the world’s population relies on karst groundwater as the primary source for drinking and irrigation. However, due to the global climate change as well as population expansion, the contradictory between supply and demand of water resource becomes more and more pronounced. Karst groundwater supply drinking water and irrigation water to more than thirty large cities in northern China due to its high concentration, stable groundwater flow and good water quality. Meanwhile, due to the excessive development of karst groundwater, a series of aquatic ecological problems have arisen, such as over 30% karst large springs are in process of drying up, the regional karst groundwater level declining and the degradation of karst groundwater quality in the past forty years.
