基于面源模型的城市内部居住环境区位优势度分析

Research on Location Advantage of Urban Residential Environment Based on Area Source Model

首先,利用ARC/INFO平台将研究区域划分成若干元胞(cell),作为居住环境区位优势度空间评价基本单元,各种统计运算以元胞为单位进行,结果通过元胞显示出来,就可以构造面源模型。运用该模型对居住环境区位优势度研究,有效解决了不同空间单元信息如何在同一单元融合的问题,弥补以往选取若干典型小区的片状研究方法的若干不足。其次,对佳木斯市居住环境区位优势度进行分析,最后,在Arcmap平台下,充分发挥GIS的逻辑查询和图形叠置功能,建立了呈不规则四圈层的单核心居住环境区位优势度评价空间结构模式图。

The ARC/INFO platform is adopted to divide the research areas into several cellular（ cell）, basic unit for evaluation of environmental advantages of living location. The various statistical operations were based on cellular which can reflect the research results were set up in a bid to construct area source model. This model effectively solved the problems of fusing different information into one spatial unit and the shortcomings of selecting several typical residential units. This paper analyzed the location advantage of living condition in Jiamusi City. The paper brings into play the function of overlay and query to establish the irregular four layer of single core spatial structure model map of location advantage of residential environment on the platform of ArcMap.
