1、农安县城镇化与建设用地集约利用耦合关系研究关键字:农安县城镇化与建设用地集约利用耦合关系研究本文为Word文档,感谢你的关注! 摘要:以吉林省农安县为研究区域,以其所辖22个乡镇为基本单元,选取反映城镇化水平和土地集约利用水平的22个指标构建了城镇化与建设用地集约利用耦合协调发展模型,在计算各乡镇城镇化指数和建设用地集约利用水平指数的基础上,进一步得出城镇化与建设用地集约利用耦合协调度和耦合协调发展度指数,并综合分析其耦合协调发展关系。结果表明,农安县城镇化水平较低,县级行政中心集聚型城镇化是县域城镇化的主要表现形式;建
2、设用地集约利用水平相对较高,各乡镇差别不大;农安镇、合隆镇和烧锅镇城镇化与建设用地集约利用耦合协调程度较高,其余19个乡镇均属于城镇化滞后的耦合失调型。城镇化水平是制约县域城镇化与建设用地集约利用耦合协调发展的主要因素,培育中小型城镇是县域城镇化与建设用地集约利用协调发展的主要方向。 关键词:县域城镇化;土地集约利用;耦合关系模型;协调度;农安县 F293.2A0439-8114(2016)21-5713-06 DOI:10.14088/j.cnki.issn0439-8114.2016.21.068 Studyo
