The invention relates to an automatic data reorganization system and a method, belonging to the technical field of hydrological data processing, in particular to an automatic hydrological data reorganization system and a method based on service dispatching. The invention realizes the integration method of the multi-user concurrent processing by establishing the integration system structure of themulti-task processing mode, constructs a data bus and a transmission link, realizes the online sharing of the data and the online sharing of the integration scheme, and guarantees the consistency of the data. The on-line mode provided by the invention can not only control the modification of the data by the user through the strategy, but also reflect the modification status of the data in real time, realize the backtracking of the modification process, and greatly improve the timeliness and the benefit. The invention automatically adjusts the integrated trajectory according to the property ofthe object and improves the automation degree of the integrated trajectory by identifying the integrated trajectory of the hydrological data and adaptively remodeling the trajectory.
