Optimization method for calculating regional weight based on drought stations

The invention discloses an optimization method for calculating regional weight based on drought stations. The optimization method comprises the following steps: S1, calculating the weight value of a monitoring station corresponding to each partition through a server; S2, multiplying the obtained weight value by the drought levels of the corresponding observation stations under the current division, and summing; S3S3, obtaining a regional drought index value, and drawing colors in a map according to national standards; sending the calculation mode to a server to calculate the weight value of the monitoring station corresponding to each zone; multiplying the weight value by the drought levels of the corresponding observation stations under the current division to obtain a sum; obtaining a regional drought index value; according to the method, calculation is executed by the server side, the server side returns the calculated drought levels corresponding to all the partitions, the colors are drawn in the map acco
