【摘要】 利用 1986年和 2 0 0 0年两个时相的航空影像进行城市土地利用解译 ,通过MapInfo、ArcView等GIS软件对矢量化的解译成果进行空间分析与查询统计。研究表明 :济南市城市土地利用结构具有明显的圈层和扇形结构特征。自内而外可分为三个圈层 ,但与西方圈层模式相比 ,又具有鲜明的特点。内圈层功能以居住和商业金融服务为主 ,且居住用地比重偏大 ;中间圈层土地利用的空间结构比较均衡 ,随时间变化较平稳 ;外层土地利用的时空变化明显 ,工业用地比重较大。各圈层又可划分为多个具有不同城市功能的扇形地域。更多还原

【Abstract】 Based on the data of urban land use obtained by remote sensing interpretation, the ring structure and wedged structure of Jinan city are studied with the aid of MapInfo and ArcView. It is indicated that the urban district can be distinguished into 3 rings. Compared with the traditional theory of Ring Structure, they have many distinctive characteristics. The main functions of the Inner Ring are residence, business and banking. And its proportion of residential land is considerable high. In the Intermediate Ring, the spatial structure of land use is relatively equal and its variation by time is relatively stable. But the structure in the External Ring varies acutely and its main land use type is industrial land. Each ring area of Jinan city can be divided into some wedge-like urban areas.更多还原
