甘肃省城市化与土地集约利用耦合协调发展

土地集约利用能够促进城市化健康发展,而城市化水平又影响着土地集约利用水平,两者的耦合协调程度是影响城市发展的关键因素。本文对甘肃省12个地级市进行实证研究,构建城市化与土地集约利用的耦合协调发展度模型,定量评价两者之间的耦合协调发展状况,并且利用地理空间分析工具进行空间聚类分析。结果表明:多数市已经从拮抗期过渡到磨合期,但是还没有进入协调期,说明甘肃省城市化与土地集约利用之间还未完全达到完全协调发展的程度;甘肃省城市化与土地集约利用的耦合协调发展度普遍较低,从2003年开始呈现出逐年扩张的趋势。

Coupling Coordination Developing Relationship between Intensive Land Use and Urbanization in Gansu,China

Intensive land use and urbanization influence each other. The coupling coordination between the intensive land use and the urbanization is an important factor influencing the urban development speed. This paper studied the 12 cities in Gansu province, and built coupling coordination developing models between intensive land use and urbanization, and quantitatively assessed their coupling coordination developing conditions, and took spatial clustering analysis by using geographical spatial analysis tools. The results show that most cities had transited from antagonism stage to compromise stage, but have not reached harmonious stage, which indicates that the relationship between intensive land use and urbanization in Gansu province have not completely achieved the coordination developing stage; coupling coordination between intensive land use and urbanization in Gansu province is generally low, and it presented yearly expanding trend since 2003.
