土地利用类型变化与城市化水平的关系研究——以南京市为例

Study on the relationship between the land use type changes and urbanization level:Take Nanjing city as an example

土地利用类型变化与城市化水平存在着密切的关系。选取南京市2005—2015年土地利用类型变化和城市化水平的相关数据,运用相关分析和回归分析,对土地利用类型变化及城市化水平的关系进行了探讨。结果表明,随着城市化水平的提升,土地利用类型也随之发生变化,其中农用地、未利用土地面积随城市化水平的提升而不断减少,建设用地面积随城市化水平的提升而不断增加。城市化水平影响着土地利用类型变化,在平稳快速推进城市化进程中,要合理开发利用土地,保持正确的土地利用规划,以期为城市合理开发与土地利用提供理论依据。

There was a close relationship between the land use type changes and urbanization level.Relevant data of the land use type changes and urbanization level in Nanjing city from 2005 to 2015 were selected,and correlation analysis and regression analysis were used to discuss the relationship between the land use type changes and urbanization level.The results showed that,as the level of urbanization increases,the types of land use also changes.Among them,the area of agricultural land and unused land continues to decrease as the level of urbanization increases,while the area of construction land continues to increase as the level of urbanization increases.The level of urbanization affects the land use type changes.In the process of steady and rapid urbanization,it is necessary to rationally develop and use land,and maintain correct land use planning,in order to provide a theoretical basis for urban rational development and land use.
