基于国土资源“一张图”的建设用地利用潜力分析——以江苏省常州市戚墅堰区为例

The Analysis of Construction Land Use Potential Based on“One Land Map”——A Case Study of Qishuyan District,Changzhou City in Jiangsu Province

基于国土资源"一张图"数据,利用资料分析法分析评价江苏省常州市戚墅堰区建设用地的利用潜力。利用Arc GIS软件系统对不同类型的数据及图层进行叠加分析,初步得到各功能区图层及各地块容积率、建筑密度等数据。基于此,从宏观和中观2个层次全面深入地分析、评价戚墅堰区建设用地利用潜力。研究结果表明,戚墅堰区建设用地利用潜力较大。该研究结果基本反映了戚墅堰区土地利用潜力情况,表明所采用的土地利用潜力分析方法科学、有效、具有示范效果,可为其他地区进行土地利用潜力分析提供参考,同时也可为深化和拓展国土资源"一张图"的应用提供策略。

Based on the ＂One Land Map＂, the construction land use potentiality of Changzhou Qishuyan District was analyzed by the method of material analysis. This paper perform overlay analysis on different types of data and layers overlapped through using the ArcGIS software, then get the layers of different kinds of land wastage, and the plot ratio of the parcels layer and so on. On the basis of those, the construction land use potentiality of Changzhou Qishuyan District was analyzed from both macroscopic and midscopic layer. And the result has shown that the potentiality of Qishuyan District exploitation and utilization is great. The results of this study are basically reflecting the construction land use potentiality of Qishuyan District, which has shown that the method of land use potentiality analysis proposed in this article is scientific and effective, also has a distinct demonstration effect as well. And the method this paper put forward could provide reference for land use potentiality analysis in other regions, and provide strategy for deepening and expanding the application of ＂One Land Map＂.
