摘要

Important urban relationships depend on the spatial gradients of population density. Urban population density gradients prove to be important in nuclear energy facility siting,strategic targeting and civil defense,industrial planning,and many varieties of energy planning problems. Following the Introductory Section,Section II turns to a discussion of Clark's hypothesis,which forms the basis for the model of population density to be used in this essay. A method of estimating the parameters of the model is presented in Section III,with an analysis of error sensitivity presented in Section IV. In Section V,the difference between a uniform density specification for a given area and a density gradient formulation,using a calculation of pollutant dose from a centrally located power station as an example is examined. Extension of the model to urban areas of non-circular form is derived in Section VI,again with emphasis on the estimation of model parameters. Section VII presents a comparison of the traditional regression technique for parameter estimation with the numerical method developed in this paper. Finally,in Section VIII,the model is applied to a sample of energy planning problems,the screening of urban areas for suitability for district heating schemes,the computation of transportation costs in the recovery of energy from municipal refuse,and a preliminary formulation of a model of power plant location in urban areas.
