ANALYSIS ON THE SPATIAL STRUCTURE OF URBAN LAND USE IN JINAN CITY
基于遥感解译数据，借助MapInfo和ArcView分析济南市城市土地利用的圈层和楔形结构，发现内圈以居住和商业为主，中圈结构均衡，外圈以工业用地为主且变化剧烈。
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.
