Analysis of Jingyu Natural Mineral Water Recharge Mechanism

Abstract

Jingyu county of jilin province is located in the core area of Changbai Mountain Nature Reserve. It belongs to the Changbai Mountain mineral water group and has a daily total flow of 151,000 m3. It is one of the most important mineral water producing areas in Northeast China and has nongfu spring, Evergrande ice springs, Master Kong and other well-known production bases. Therefore, it is of great significance to the local government and society to clarify the mineral water recharge mechanism in Jingyu Nature Reserve and ensure that the mineral water in the protected area is sufficient. In summary, in order to ensure the sustainable scientific development and utilization of mineral water in this area, this paper takes into account the local geological and hydrogeological structural characteristics, and uses the environmental isotope method to compare the hydrogen and oxygen isotopes of mineral water in the study area with atmospheric precipitation in the area. According to the isotope change law, the origin, formation conditions and recharge mechanism of the local groundwater were revealed. The conclusions are as follows: the main source of mineral water in Jingyu Nature Reserve is atmospheric precipitation, and the cycle time is 20 to 40 years.
