摘要
以大连市为例 ,首先利用ARC/INFO软件将研究地区划分成 162个元胞作为评价的基本空间单元 ,建立了居住环境评价的面源模型。其次利用MDS方法确定了评价因子、列联表法验证了居民属性与居住环境评价之间的相互独立程度、因子分析方法探讨了居住环境评价结构的平行性。最后应用GIS对居住环境评价空间分异现象进行了分析。
This paper introduces a new kind of evaluation approach of residential environment based on Area Source Model. Cell (1 km×1 km size of raster unit) is partitioned in the study area, which is realized in raster GIS platform (ARC/INFO GRID sub-modular). Dalian city is divided into 162 cells whose attributes are acquired and calculated from the questionnaires. When processing, evaluative indexes are determined by MDS method. Independent degree of resident attributes and evaluation of residential environment are tested by the method of Crosstab. Parallelism of evaluative difference of residential environment is discussed by the method of Factor Analysis. Finally the paper analyzes spatial difference of evaluation of residential environment by the spatial analysis of GIS, and the following points are resulted. Firstly, evaluative values of convenient environment fall from the center to the skirt step by step. Secondly, evaluative values of circumferential environment are affected by zone characteristics, especially the types of urban land-use to a great extent. Thirdly, evaluative values of human environment are not regularly diverse. Finally, evaluative values of residential environment have three epicenters of Zhongshan Square, Carrefour Supermarket and the edifice of municipal government.
