Urban flood toughness evaluation modeling method based on low-carbon sustainable index coupling

The invention relates to the technical field of urban flood toughness analysis, and discloses an urban flood toughness evaluation modeling method based on low-carbon sustainable index coupling. The urban flood toughness evaluation modeling method combines a CRITIC-entropy weight method combined weighting method and a TOPSIS evaluation method to measure and calculate the flood toughness and low-carbon development level of a research area. And the coupling coordination condition of the two is measured by using a coupling coordination model. According to the method, through a three-dimensional flood toughness and low-carbon development level evaluation framework, an evaluation model is more comprehensive, coupling coordination analysis is carried out on two evaluation results, the flood toughness and low-carbon development level evaluation results of a traditional community and a low-carbon community can be successfully calculated, the coupling coordination relationship between the traditional community and the
