摘 要: | 该文以2006年LANDSAT-5卫星获取的TM影像为基础数据源,在ARCGIS和ENVI软件的支持下,应用景观紊乱度模型,分析熵值分布特点,以建成区边缘为内边界,以景观紊乱度值0.4为域值确定外边界,最终确定南宁市城郊结合部范围及各乡镇与城郊结合部的归属关系,为南宁市规划部门及管理部门提供科学依据.

Abstract: | In order to meet the need of scientific management and planning of urban land, moreover, to consider the illegibility of the range of Urban-Suburban-Integration Area (URIA) and difficulties in managing it, this paper redefines the district range of URIA. Meanwhile , taking Nanning as the case, the author tries to extract the exact range of URIA with the help of Remote Sensing (RS) and Geographic Information System (GIS) techniques. |
