土地利用空间变化的定量分析与管理对策——以吉林省长春市宽城区为例

Management strategies of land-use space change——Take Kuancheng District,Changchun City,Jilin Province for instance

以吉林省长春市宽城区为例,结合宽城区自然状况和土地利用现状,采用均质度变化作为土地利用空间变化的研究方法,运用GIS技术对宽城区土地利用现状图进行网格化,建立了均质地域方格网.讨论了土地均质度变化和用地类型变化之间的相互影响关系,得出在经济发展的转型期,长春市用地均质度的变化呈现先慢后快、先近城区后远城区逐渐呈变的特点.针对目前存在的不同问题,相应提出了集约的土地开发模式、营造疏密有致的城市空间、有机协调各类功能空间以及留足城市开放空间等管理对策,为指导宽城区未来土地合理利用具有重要意义.

The article takes Kuancheng District,Changchun City,Jilin Province for example,talking about the natural conditions and current land-use space change of Kuancheng District,putting homogeneity changes as the research methods of land-use space change,using GIS technology to make gridded map of land-use space change and establish the homogeneous geographical grid network.Explore the relationship between changes in land homogeneous degree and in land use types,and concluded that in the transition of economic development,the change of homogeneity of Changchun rendered high speed after low speed and the range from next to the city to far away from the city.Propose management strategies of land-use space change pointed at the current problems of Kuancheng District.Put forward management countermeasures following：establishing intensive land development pattern,creating the density of city space,coordinating various functional organically and retaining the city＇s open space management.It has important guiding significance for rational land use in Kuancheng District.
