Modeling the spatial distribution of urban population density and its evolution in Hangzhou;

A method for urban population density computing based on extended space syntax

GIS based urban population spatial distribution model and application in Changchun;

The paper analyzed a lot of confusion on China s basic urban concepts such as "urban place" , "urban population" , "urban scale" and "urbanization" .

The relation of urbanization course and water resources use has been explored from urban population increase,urban industrial structure and urbanization course,and then the strategy for sustainable use of water resources,which fit in with urbanization development,is set up.

Up to the present time, Chinese publications still usecity non-agriculture population and city total popu-lation as the indexes for city population size.

According to the data and materials of gazetteers, this paper is trying to build models of City\|Population Degree of Jiangsu and points out that the percentage of city population, which is partly dependent on the number of city population, is mainly determined by the number of the total population in the area.

Through analyzing the two common evaluation indexes of intersection traffic condition,consist of intersection traffic capacity and intersection saturation degree,and on the basis of determining service level of each directional traffic line,the feasibility of grade crossing be separated can be determined comprehensively according to the position of grade crossing in the urban density area.

This paper analyzes on the theoretical foundation of the tighten city morphology and the problems existing in it, and points out that only controlling the urban density in a rational scope could implement the sustainable development of the city.

On the basis of systematic analysis on urban rational scale of population,Possibility-Satisfiability model as multiple aim decision was used.
