Urban optimization construction method based on evaluation result of healthy cities in subtropical regions

The invention discloses a city optimization construction method based on a subtropical region healthy city evaluation result, and the method comprises the steps: constructing a subtropical healthy city evaluation index system based on the existing healthy city evaluation indexes and subtropical city health influence factors; dividing the target city area into a plurality of grids according to the scale; collecting data corresponding to the subtropical healthy city evaluation index system in the target city area, and calculating values of a plurality of indexes of each grid according to the data; carrying out standardization processing on the values of the plurality of indexes, and determining the weight of each index; calculating a healthy city comprehensive evaluation value of each grid based on the value and the weight of each index after standardization processing of each grid; and the grids with the comprehensive evaluation values of the healthy cities smaller than the evaluation threshold are identified
