Summary:The invention discloses a base flow segmentation method and device based on seasonal conductivity data correction, and the method comprises the steps: collecting data, including daily runoff and conductivity data; performing base flow segmentation by using a CMB method to obtain a day-based flow, and taking a segmentation result as a standard for subsequent ECK method parameter correction; correcting ECK method parameters year by year and season according to a CMB method segmentation result, taking day-based flow data obtained by the CMB method as a standard, searching an ECK method parameter combination enabling a basic flow calculation error to be minimum, and obtaining an optimal parameter combination in a wet season and a dry season; and carrying out base flow segmentation calculation by utilizing the corrected ECK method optimal parameter combination. According to the method, the advantages of the CMB method and the ECK method are fully utilized, the accuracy and reliability of the base flow segmentation
