After the analysis of the hydrochemical,hydrogen isotope and oxygen isotope in 4 wells (springs) and surface water of its surrounding areas in Shanxi Province by the Piper diagram,durov diagram,and Na-K-Mg triangulation,the equilibrium degree of water rock,the temperature of heat storage,the depth of groundwater circulation and the source of groundwater recharge are observed. The seismic reflection characteristics of the well (spring) water radon measurement are analyzed,and the characteristics of the earthquake monitoring effect are evaluated by using the characteristics of the water radon reflection effect and the water-rock balance and the groundwater circulation depth. The result presents that the Xiaxian well and Qicun well are fitter than the Linyi well to be used to observe hydrochemical characteristics,and Dingxiang well in hydrochemical evaluation is still insufficient,and needs new method.
