Research on Beijing human settlement in district level by GIS spatial analyzing

Abstract

This paper mainly focuses on human settlement of livable city appraisal system to research evaluation criteria, using Spatial Analyzing in Arcinfo, to unify objective evaluation system, to conduct analysis research from the spatial angle to Beijing residential environment healthy, by subjective and objective aspects, there has conducted the spatial analysis research on urban residential environment. The research indicated that:1) Beijing urban district residential environment healthy satisfaction degree level still permissible, has obvious spatial autocorrelation characteristic. The satisfaction degree of spatial difference research to indicate that, satisfaction degree overall existence by take urban center as zero point to the periphery emission, section presents the saddle characteristic, has satisfaction degree nearby transportation node concave region, simultaneously, some islet existence, also causes to spatial distribution of livable city satisfaction degree to be more complex; 2) uses Beijing Environmental protection Bureau issue 2000-2006 year correlation data, carries on objective evaluation using factor analysis method to Beijing environment healthy in recent years, discovered atmospheric and noise pollution does not present rule change tendency; 3) residential environment healthy system will divide into atmospheric, water, noise and solid reject four sub-systems, will carry on subjective and objective appraisal to Beijing synthesis contrast analysis, north city is higher than western city regarding air pollution appraisal. In central city Xicheng District and Chongwen district's inhabitant has the enhancement regarding air pollution appraisal, but Xuanwu district and Dongcheng district's air pollution condition still had certain disparity from public satisfaction; The noise appraisal aspect, east city is higher than western city, the central city satisfaction degree has rise except Xuanwu district. The plan and construction provides the countermeasure suggestion through above conclusion for Beijing urban residential environment healthy. This will have the vital significance regarding Beijing future development and lives of people residential environment quality enhancement.
