Display method and system for comprehensive drainage information monitoring

The invention provides a display method and system for comprehensive drainage information monitoring. The method comprises the steps that 1) a topological relation diagram is established according to a practical geographical information graph of elements of a drainage system of a monitoring area, the elements include pipelines, pump stations, river channels, sluices and dikes, the display color of each element is determined according to the corresponding state of the element, and each element also comprises monitoring information correspondingly; 2) the present states of the elements are determined according to the monitoring information collected by the elements regularly, and the display colors of the elements in the topological relation diagram are updated according to the present states of the elements; 3) the corresponding topological relation diagram is provided according to a data request and the authority of a user who makes the data request; and 4) a display level is determined according to a display
