基于直觉模糊理论的安徽省生态宜居城市评价研究

Study on the Evaluation of Ecological Livable City in Anhui Based on Intuitionistic Fuzzy Theory

通过对安徽省主要城市的生态宜居性做研究比较,为生态宜居城市建设提供参考依据。首先从经济发展、基础建设、生态环境和社会民生等4个方面构建评价指标体系,利用直觉模糊理论构建生态宜居城市评价模型,采用直觉模糊熵计算指标权重;然后通过采集安徽省16个城市2013—2016年的指标数据进行实例验证,得出安徽省主要城市的生态宜居性排名;最后由评价结果分析出空气质量优良率、第三产业占全市GDP比重等指标在宜居城市评价中贡献率较大,并给出建设生态宜居城市的相关建议。

Through the study and comparison of the ecological livability of the main cities in Anhui Province,it provides a reference for the construction of ecological livable cities. First of all,the evaluation index system is constructed from four aspects： economic development,infrastructure construction,ecological environment and social livelihood. Based on intuitionistic fuzzy theory,an evaluation model of ecological livable city is constructed,and intuitionistic fuzzy entropy is used to calculate index weight. Then by collecting the data of 16 cities in Anhui province from 2013 to 2016,it is proved that the ecological livability of the main cities of Anhui province is ranked. Finally,based on the evaluation results,we can see that the contribution rate of air quality excellence rate,the third industry proportion to the GDP and so on are larger than that of the livable city evaluation,and give some suggestions for building an ecological livable city.
