长三角城市群生态城市建设定量评价

长江三角洲是我国发育最为成熟的城市聚集区，随着城市发展主流趋势--生态城市的日益兴起，区内各城市相继开展了生态城市建设，并取得了相当的成效。但是在生态城市建设过程中还不可避免地存在着城市复合生态系统不协调发展、生态城市建设程度难以定量以及片面定量的问题。试从长三角城市群社会经济和地域情况入手，构建具有地方特色的生态城市建设指标体系，并采用城市生态指数、城市协调度指数和生态城市综合指数来分别衡量长三角城市群内各城市的生态化水平、城市协调发展水平和生态城市建设程度。结果表明：（1）长三角城市群15个城市中，苏州生态城市建设程度较好，而南通则略差；（2）只有城市的全面协调发展，才能建成可持续发展的生态城市。
