【 摘 要 】

All Based on the statistics of water use in the past five years, this paper uses the projection pursuit method to evaluate the rational use of water resources in various provinces and cities in China, and establishes corresponding prediction models for the completion of red line indicators. Perform preliminary statistical analysis on the data, select relevant indicators to establish a projection pursuit evaluation model, and use the genetic algorithm to solve the problem, display the projection values of each province and city on the map, and point out the existing problems. Four of the red line indicators were exponentially fitted and predicted. The final water quality compliance rate did not reach the red line target value of 2030, and the deviation from the target was 13.68%.
