- Abstract:
- Based on the tendency rising of water temperature in the Lijiang observation well since 2012,we analyzed its hydrological change process,and analyzed the chemical characteristics of groundwater and its hydraulic connection with surrounding water bodies by using the Piper diagrams,Schoeller diagrams,and hydrogen and oxygen isotopes etc.Then,we discussed the rising reasons of water temperature in the well. The results show that the groundwater type was HCO3-Na type under the cutoff state,when the well affected by the deeper groundwater runoff. Its type was HCO3-Ca under the drainage state,when it was direct recharge of atmospheric precipitation. The water-rock reaction degree of the well is weak,and it has obvious hydraulic connection with the surrounding water body. It is greatly affected by surface water,and carries less deep information. After the well was dried up in 2012,the water temperature was continuously rising due to the rise of deep hot water. Influenced by rainfall in rainy season,the water temperature showed a certain degree of annual deformation with the change of water level. The analysis result shows that the precursory characteristics of this period are not obvious.
