城市宜居程度的一个评价模型

An Evaluation Model on the Degree of Urban Livability

针对宜居城市评价指标问题,在合理的假设条件下,采用理论分析法和频度统计法筛选出主要指标(包括5个一级指标和8个二级指标),利用熵值法建立了评价宜居城市的数学模型。然后以8个城市为例,计算出一级指标和二级指标的权重,以及每个二级指标的熵值,从而给出8个城市综合得分排名。最后,得出生态环境和文化教育这两个指标的变化会对宜居城市排名产生显著的影响。

Aiming at the evaluation index of urban livability,based on the reasonable assumptions,by theoretical analysis and frequency statistics,the main indexes（ including five first-level indicators and eight second-level indexes） were selected. Using the entropy method,mathematical model of urban livability is carried out. Then,taking the eight cities as examples,the weight of the primary indexes and the secondary indexes,the entropy of secondary indexes are calculated. So the overall score ranking of the eight cities is given. Finally,it is obtained that the changes in the eco-environment and cultural education have significant impact on the degree of urban livability.
