Research On The Relationship Between Natural Mineral Water And Surface Water In The Basalt Area Of Changbai Mountain

The research on the relationship between natural mineral water and surface water in the Changbai Mountain basalt area is of great significance to the study of water resources protection,watershed ecosystem protection,water resources management and development and utilization.The Changbai Mountain basalt area has abundant mineral water reserves,excellent water quality,and great development and utilization potential.However,the ecological system in this area is relatively fragile.If it is destroyed,it will be difficult to effectively restore it.The study area is located in the eastern mountainous area of Jilin Province,where there are dense rivers and the surface water system is very developed.Therefore,the research on the relationship between natural mineral water and surface water in the study area is to further explore the transformation relationship of"surface water-mineral water"in the more typical mineral water storage area,and for the rational development and utilization of mineral water in the future.The government's decision-making and management provide guidance.Based on the full understanding of previous research results,this paper divided the study area into typical watersheds.In the watershed,water points of major rivers and mineral water points along the banks were selected to measure flow and water sample tests.Qualitative and quantitative analysis of the relationship between surface water and mineral water was carried out using hydrochemical methods and isotopic methods.The main results obtained in this paper are as follows:?1?Analysis and transformation relationship of geological and geographic conditions:The water levels of river sampling points and coastal spring water sampling points in the study area were measured in July and November,and the water level relationship between the two was visually presented through the profile diagram,and found In July and November,most springs replenish the river water.Some springs with a small elevation difference from the river level receive replenishment from the river after the water level rises,such as Laiya Spring,Shenxi Spring,and Songhua Spring.?2?Analysis of the transformation relationship by hydrochemical methods:by measuring the ions of the river water and mineral water sampling points in the study area,and analyzing the characteristics of metasilicic acid and Cl-along the change,the river water received spring water replenishment in November.In July,the river water continued to receive spring water replenishment,and a small amount of spring water received river water replenishment,and the information exchanged by the water body can be intuitively reflected in the law of tracer changes along the way.The supply of river water to Laiya Spring,Shenxi Spring,and Songhua Spring in July are:0.008-0.01m³/s,0.006-0.008 m³/s,0.018-0.061 m³/s;?3?Isotopic analysis of the transformation relationship:through the detection of stable isotopes D,¹⁸O,and radioisotope ²²²Rn in river water and mineral water in key research areas,and measurement of river water flow and spring water flow,according to the law of conservation of mass,along the way Quantitative analysis of the conversion of surface water and mineral water.Among them,the supply of river water to Laiya Spring,Shenxi Spring,and Songhua Spring in July are:0.0034 m³/s,0.0084m³/s,and 0.0379 m³/s;?4?The three methods are combined,and the average value is calculated as the total amount of surface water supplied by spring water from July to September and November.From July to September,the total amount of spring water replenishing surface water in the key research area was 3.52 m³/s,the total amount of spring water replenishing surface water in the key study area in November was 1.59 m³/s,and the total amount of surface water replenishing spring water in July was 0.053 m³/s.
