Model of Estimating Population Density in the Residential Quarter of Urban
城市居住人口密度估算模型的研究

Urban population decides the scale of urban,and the structure and dis-tribution of urban population are the principal factors for considering in urbandeveloping and planning.This paper discusses the establishement of a spatialdatabase of land resource by using the GIS software of ARC /INFO. The inputingdata are obtained from the landuse map surveyed with aerial remote sensing imagesin Shanghai.As an application of the database,we develop a model of estimatingpopulation density which related to reside land area. By means of linear regressionmethod,the model is getting best salve of population density to various kinds ofresidential land types. This paper also discusses some problems in building up the model using landresource database and provides concrete solving methods in the example of PutuoDistrict,Shanghai.The result in the example is satisfied.
