Spatial Analysis Of Evaluation Of Urban Residential Environment

People pay more attention to residential environmen, city residential environmentquality undertakes quantitative analysis is one of the research hotspots in the city. This paperuses the GIS, grid computing and spatial data autocorrelation model combination methods,selection of Jia Musi city as the research object, on the internal evaluation of residentialenvironment spatial pattern of exploratory analysis.First of all, the use of ArcMap platform will be the study area is divided into a pluralityof identical size cellular (cell), as the basic unit of evaluation of residential space, to cellular(cell) as the unit for various statistical calculation, calculation results through cellular (cell)display, can build residential environmental evaluation of surface source model. Applying themodel to the study on the living environment, solved effectively in the same unit on differentspatial units how information fusion problem, make up for the previous selected severaltypical district as the evaluation unit of certain deficiencies. Secondly, based on thequestionnaire survey to determine Jia Musi city evaluation index system, again livingenvironment satisfaction survey questionnaire, data as a basis for standardization of treatment,through factor analysis method (FA) to verify the evaluation index system and the actualaccuracy, using the analytic hierarchy process (AHP) to determine the index weight, and theestablishment of space attribute integration database, as a basis for the evaluation of. Finally,the Jia Musi city living environment quality conclusion: surrounding environment highquality evaluation in Xinglin Lake Park and the surrounding area in Xilin Park and riversidelandscape belt of small portion of the area, the surrounding environment quality evaluation inthe very great degree the regional characteristics, especially the land use types; convenientenvironment quality evaluation high evaluation area height focused on the city block, fromdowntown to the edge of the city gradually reduced, evaluating value and downtown spacedistance exists significant negative correlation, basically follow space attenuation law;cultural environment quality evaluation in the500m x500m mesh under the premise of not obvious spatial differentiation rule, random distribution in the study area, the thoroughdiscussion from the angle of residential property is more effective.Give full play to the GIS logical query and graphic overlay function, establish theirregular four layer of single core living environment quality evaluation of space structurepattern; by spatial autocorrelation model on the assessment unit, the immanent connectionbetween conducted exploratory analysis, found the living environment is the spacedistribution pattern to show the overall convergence and local difference. And from the angleof space associated to the study area, puts forward the spatial layout and planning scheme.
