本文以成都市为例,针对性地提出成都市保障性住房适宜性评价指标体系。接着采用权值因子判断表的方法对各个影响因子赋予相应的权重。然后将影响因子在Arc Gis软件上分为图层表现出来,并按照住区设计规范等理论和调研成果来分析每个影响因子的适宜性等级并对其重分类。进而将各个因子图层按照权重进行加权叠加,最终得出成都现有保障性住房的空间区位布局的适宜性评价。 This article takes Chengdu as an example, puts forward the index system of Chengdu affordable housing suitability evaluation. Then use the method of weight factor to determine the table on each impact factor given the appropriate weight. Then, the influence factors are shown on the Arc Gis software layer, and according to the theories and research results of the design codes of settlements, the suitability grade of each influencing factor is analyzed and reclassified. Then, the various factor layers are weighted and superposed according to the weights, and finally the suitability evaluation of the spatial distribution of the existing affordable housing in Chengdu is concluded.
