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

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