Data analysis method and system based on debris flow monitoring

The invention provides a data analysis method and system based on debris flow monitoring, and the method comprises the steps: carrying out the debris flow feature recognition of a state change node through obtaining a state change node sequence corresponding to a monitoring state change path of monitoring data of a target debris flow region, generating debris flow feature recognition data containing potential risk knowledge points, and carrying out the recognition of the debris flow feature. And detailed data support is provided for debris flow early warning. The reference debris flow event and the feature mode vector thereof are determined based on the debris flow feature identification data, the mode of the debris flow event can be accurately identified, and the mode of the debris flow event is compared with the mode of the known debris flow event to generate debris flow judgment data, so that the accuracy of debris flow early warning is improved through the comparison process; and unknown debris flow event
