The invention discloses a power grid multi-state and multi-dimensional display control method based on a geographic information system. The power grid multi-state and multi-dimensional display control method includes steps: calculating weights of all map blocks by aid of a weighting distance and power grid information amount of the map blocks aiming at a current visible area in the geographic information system; sorting the weights of all the map blocks and selecting partial map blocks with large weights and loading the map blocks into an internal memory in advance; and when the number of the map blocks in the internal memory reaches the preset threshold, calculating the weight of each cached map block, sorting the weights of the cached map blocks and releasing partial map blocks with small weights. By using the power grid multi-state and multi-dimensional display control method, the geographic position and the network topological relation of power grid devices can be sufficiently displayed, global management on state information and operation information of the power grid devices is facilitated, longitudinal resource sharing of state information and parameter information of the upper level power grid device and the lower level power grid device is achieved, and province and region integrated management of the power grid devices can be achieved conveniently.
