Evaluation method for coalmining-based cities ecosystem based on attribute mathematical model with Huainan City as an example

- Construction of the criterion indicators of coalmining-based cities ecosystem classification.
- The attributive measurement of single indicator and multi-indicator.
- The synthetic attributive measurement is calculated by the AHP.
- The health classification of cities ecosystem are recognized by the confidence criterion.
- An empirical analysis is made by the proposed model and method.

Attributive recognition model of coalmining-based cities ecosystem classification is developed in terms of attributive mathematical theory. Based on the analysis of main causes of coalmining-based cities ecosystem, the city vitality, city structure strength, city resilience ability, service functions and health status are chosen as the criterion indicators of coalmining-based cities ecosystem classification; the attributive measurement functions are constructed to compute the attributive measurement of single indicator and multi-indicator; and the synthetic attributive measurement is calculated by the AHP; the health classification of cities ecosystem are recognized by the confidence criterion. An empirical analysis is made by the proposed model and method, the synthetic evaluation results are better than fuzzy comprehensive evaluation method which validates the proposed model feasible, effective and reliable in coalmining-based cities ecosystem classification. As attributive recognition theory can success fully resolve certain issues with a number of fuzzy attribution in comprehensive evaluation, its confidence criterion is established on the basis of the ordered evaluation sets, consequently it will make the evaluation results more reliable.
