Hydrological Characteristics of Spring Water in Different Positions of Jinci Spring Discharge Area
HE Xiangnan
Abstract：The reflow of Jinci Spring which has been cut off for 30 years is a landmark achievement of groundwater management and spring protection in Shanxi Province.This paper analyzes the hydrological characteristics of Jinci Spring and Ping Spring located in different discharge areas from three aspects:hydrogeological conditions,water level dynamic law and flow dynamic characteristics.It is found that,Jinci Spring and Ping Spring belong to the same karst water system,but they have their own relatively independent sections.Ping Spring not only receives the recharge from Jinci Spring,but also receives the recharge from the western detention area.Both annual water level dynamics show the characteristics of"first peak and then valley".Compared with Jinci Spring,the interannual water level of Ping Spring is characterized by large fluctuation and variation coefficient,negative skewness and sharp kurtosis.Before the break of the flow,Ping Spring captured part of the flow of Jinci Spring,which was one of the reasons for the rapid attenuation of its flow.During the reflow,the water level of Ping Spring rises rapidly,the characteristics of the first outflow are the indication of the reflow of Jinci Spring.
