基于模糊综合评价的淮海经济区城市宜居性研究

Research on City Livability in Huaihai Economic Zone Based on the Fuzzy Synthetic Evaluation

城市宜居性是现代化城市建设的重要评价指标。基于"宜居城市科学评价标准",采用模糊综合评价和主成分分析法,从经济、环境、社会、资源、安全、生活6项一级指标对淮海经济区城市的宜居性进行评价。研究表明:徐州、连云港、宿迁是淮海经济区城市中较宜居的三大城市,城镇居民人均可支配收入、空气质量、人均可用淡水资源总量、人为灾害发生率是影响城市宜居性排名的主要因素。淮海经济区宜居城市建设应以经济建设为基点,注重资源承载能力,增加生态环境保护投入,加强城市安全建设,满足居民衣食住行的基础上安居乐业。
