土地利用分区与主体功能区协调的实证研究——以环鄱阳湖区为例

STUDY ON LAND USE ZONING IN THE REGION AROUND POYANG LAKE BASED-ON MAJOR FUNCTION ORIENTED ZONING

协调土地利用分区与主体功能区对于指导区域空间有序开发、实现区域土地利用的差异化管理具有重要的理论和现实意义。首先从分区目标、分区内容、分区指标和分区方法等4方面分析了主体功能区和土地利用分区的关系,指出两者的协调应在战略层面实施;然后以环鄱阳湖区为例进行实证研究:根据研究区主体功能分区图、土地利用现状图、土地适宜性评价结果图等,通过制定基于主体功能区的土地利用分区属性赋值规则,在ArcGIS9.2中进行叠置分析和空间聚类分析,得到环鄱阳湖区土地利用分区图,将环鄱阳湖区划为农业用地区、生态林用地区、城镇及工业用地区和湿地保护区,并提出了相应的土地用途管制措施。结果表明,将主体功能区成果应用于土地利用分区,有利于在用地上落实分区成果、实现地域功能管制。

There are important theoretic and practical significances for coordinating land use zoning and major function oriented zoning because it is good to keep orderly development within its spatial area and carry out differential land use management. The relation of land use zoning and major fimction oriented zoning are analyzed by zoning purposes, contents, targets and methods. So the coordinating should be put in practice in strategic layer. This paper takes the region around Poyang Lake as a study case and implements some researches as following： first, the attribute assignment regulars of land use zones based on main function zoning were established. Secondly, on the basis of a series of map including major function oriented zoning map, land use map, land suitability evaluation map and so on, the land use zoning map of region around Poyang Lake was obtained by using overlay analysis and spatial cluster analysis in ArcGIS9.2. The region around Poyang Lake was divided into 4 kinds of land use zones including farming land use area, ecological forestry land use area, urban and industrial land use area and wetland reserve area. Subsequently, land use control measures were proposed corresponding different land use zones. The result of researches shows that land use zoning based on major function zoning are good to practice the zoning results and achieve regional function control.
