The application discloses a kind of face, block and point scale linkage flood warning method based on river forecast water level in plain area, according to the flood face scale early warning of plain representative site, for having face scale early warning area, using GIS technology and the spatial autocorrelation of plain area water level in flood forecast process, calculate submerged grid and depth, carry out block, point scale early warning.The method is a kind of simple, fast method.It includes the following steps: collecting plain area basic data;A kind of face, block and point multiscale linkage early warning mechanism;Compare regional representative site forecast water level and characteristic water level, dike elevation, and carry out face scale flood risk early warning;With face scale early warning area as unit, obtain regional forecast water level face data, generate the submerged grid and water depth of regional unit, and carry out block scale early warning;With face scale early warning area as unit, in combination with submerged face, submerged water depth and flood risk point data, utilize spatial analysis technique to carry out point scale early warning.
