Problems solved by technology
[0005] This is because, at present, groundwater recharge is used for short-distance on-site recharge and on-site mining, and the technical bottleneck of long-distance accurate recharge is still difficult to solve

specific Embodiment approach
[0098] As a specific implementation, this embodiment selects the data on June 14, 2016 (the lowest day of the spring water level in this year) to draw the contour map of the karst groundwater level in the dry season, and draws the data on August 22, 2016 (the highest day of the spring water level in the current year). The contour map of the karst groundwater level in the wet season; select the data on April 21, 2018 (the lowest day of the spring water level in this year) to draw the contour map of the karst groundwater level in the dry season, and the data on September 3, 2018 (the day of the highest spring water level in the current year) Draw the contour map of the karst groundwater level in the wet period. After comparative analysis, the confluence trend reflected by the four contour maps is consistent, so the contour map drawn based on the data on September 3, 2018 is selected as the map of the confluence trend of groundwater to the karst spring, as shown in image 3 shown...

Abstract
The invention discloses a method for determining the replenishment source of a large karst spring, and relates to the technical field of hydrogeology. The method includes, first, arranging monitoring points. Second, monitor the monitoring points identified in the first step to obtain spring water level, spring electrical conductivity, spring temperature, spring flow, water level, electrical conductivity, temperature, and secondary rainfall of each aquifer. Third, draw a trend diagram of confluence according to the monitoring data in the second step; fourth, establish a correlation model between the spring water level and the water level of the aquifer monitoring point, and determine the recharge range 1 according to the model. Fifth, according to the monitored spring water level and secondary rainfall, determine the recharge range 2. Sixth, by establishing the electrical conductivity fitting model of Baotu Spring, determine the proportion of replenishment sources, and then determine the range of replenishment sources III. Seventh, superimpose the supply ranges 1, 2 and 3 obtained in the fourth, fifth and sixth to determine the supplementary source zone. This method can accurately determine the source of replenishment of the karst spring, which provides prerequisites for the later replenishment work.
Description
technical field [0001] The invention relates to the technical field of hydrogeology, in particular to a method for determining replenishment sources of large karst springs. Background technique [0002] With the rapid development of social economy, due to the increasingly prominent contradiction between water supply and demand and geological environmental problems, since the 1960s, countries around the world have carried out artificial groundwater recharge. In 1970, a symposium on artificial groundwater recharge was held in the United Kingdom, and in 1973, an international academic symposium on artificial recharge was held in New Orleans, USA. According to statistics, the amount of artificial groundwater recharge in Germany accounts for as high as 30% of groundwater exploitation, and 24% in the United States. China began to study the artificial recharge of groundwater in the 1950s, and in the 1960s, Shanghai used artificial recharge of groundwater to control land subsidence...
