    Abstract:

    At present, the sudden change of radon content in ground water is regarded as a better index of immediately prior to the occurrence of earthquake. In this paper, our discussion will centre on the interferences presented in the sudden change of radon and their causes.
    Based on the experimental results obtained from the field test station of radon measurement, we point out that many factors, such as methorological (rainfall), geological (landslip), hydrogeological (change of the hydrokinetical condition), environment of spring site(outcrop condition) and other accidental factors can lead to the mutation of radon content. For this reason we must take suitable measures to learn springs(wells) conditions so as to carry out the observation. only when the interferences are removed the precusor anomalies become may outstanding.
    In this paper, we have also made discussion on the methods of distinguishing and eliminating the interferences. It is fully proved that to set up the hydrochemical station in the tectomic region and carry out comprehensive hydrochemical observation and research (including rodon dissolved gas and other chemical components)at more stations is an effectual way to identify interferences and define out the way forward for developing earthquake prediction by hydrochemical method.
