摘要
本文尝试在地理信息系统的支持下,以商业土地级差地租为研究对象,通过建立土地、交通和人口等空间数据库,分别对商业区位、交通和人口三个评价因子定量化,并采用地理环境辨识模型建立了综合评价指标来进行城市商业地租的等级划分.本文同时还以上海市普陀区为例,讨论了运用地理信息系统软件ARC/INFO进行数据提取的一系列方法.最后,建立了该区土地等级空间数据库,并根据输出的土地等级分布图初步分析了土地规划方向.
This paper approaches to grade commercial land differential rent in cities based on Ge-ographical Information System(GIS). Firstly, the three quantitative indexes of evaluating factor: commercial location, traffic condition and population density, are established sepa-rately in the support of the spatial database of land, traffic and population. Then, a uni-fied evaluating index is created by using the model of discriminating geographic environ-ment. Finally, the spatial database of commercial land rent class was established and primitive land plan was discussed according to the map of land rent class in the example of Putuo district, Shanghai. Meanwhile, a series of methods for extracting the data are de-veloped by using PC ARC/INFO toolkits.The result shows that the study provides not only a valid means to appraise commercial land prices for land administration, but also the reliable basic data for urban planning.
