Rainfall monitoring station network evaluation and optimization method for real-time flood forecasting demand

The invention discloses a rainfall monitoring station network evaluation and optimization method for real-time flood forecasting demands, and the method comprises the following steps: (1), obtaining data and data, specifically, the data and data comprise monitoring station basic data, meteorological data and ground monitoring data; (2) rationality evaluation: analyzing the rainfall monitoring capability of the existing station, the allowable thinnest station network density, calculating the number of stations which should be set, analyzing the correlation of station network information, and analyzing the correlation, transitivity and attenuation of the station network information; and (3) station network optimization: station importance sorting, multi-dimensional multi-target station network layout optimization model, redundant station elimination, station network evaluation, station network layout principle, station addition, and station network final optimization scheme. According to the method, multiple in
