首先,根据大连市城市居民居住环境评价的问卷调查资料,利用因子分析方法构筑了由周边环境、利便环境和社区文化环境组成的居住环境评价构造。多元回归分析表明,利便环境、周边环境和社区文化环境在居住环境评价的重要程度依次降低。其次,利用ARC/INFO平台下划分的162个1km×1km的网格对居住环境评价的空间结构进行分析。周边环境高评价地区主要位于市区边缘和市中心的部分地区,后者与城市广场和绿地有关;利便环境评价由市中心到市区边缘渐次降低,与各地到市中心的时间距离显著负相关,高评价地区高度集中在市街区。利便环境评价则不存在明显的分异规律。最后,在ArcView平台下,充分发挥GIS的图形叠置和逻辑查询功能对居住环境进行评价,并建立了呈不规则四圈层的双核心居住环境评价空间结构模式图。
Firstly the paper builds residential environment structure consisting of circumambient environment, convenient environment and human environment by means of factor analysis, on the basis of questionnaires about evaluation of urban residential environment in Dalian. And from the result of multivariable regression analysis, we can see that importance of circumambient environment, convenient environment and human environment falls in turn. Secondly the studied area is divided into 162 grids of 1km?1km on the platform of ARC/INFO, which is used to analyze spatial structure of evaluation of residential environment. High evaluation of circumambient environment lies in the skirt of Dalian City and parts of downtown. The latter bear on squares and greenbelts of the city. The result of evaluation of convenient environment falls from the downtown to the skirt gradually, which has negative correlation with the distances between each area and the downtown. High evaluation of convenient environment lies in the block of the city. There is not obvious discrepancy law in evaluation of convenient environment. In the last, the paper brings into play the function of overlay and query to evaluate residential environment and builds double-kernel spatial structure model map of evaluation of residential environment on the platform of ArcView.
