Abstract:

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.
