Research On Urban Growth Model And Reasonableness

Someone looks city as a organism.Land is its fountain,and all kinds of theconstructions is entity.As every organism, the process of the urban growth obeies manydisciplinarian too, and it is a course that growed from a little to a big one,a simple to acomeplex one.As the master of the city,it is very important that the human realize thecourse deeply and intensively, especially to their existence.So,the paper aimed to analysethe process of the urban growth and the reasonableness exhibited in the course,which are infavor of the human existence.From the static and fragment study on the urban spacial structure, through definitingthe scope of the urban and the meaning of the urban spacial structure,basing on the landuse, which is the origin of the urban growth, the paper attempts to provide a cleartheoretical framework and foundation.Then,the paper turned to analyse the dynamic evolvement of urban growth.Fromresolving what is the urban growth to analysing the motive force, and then to concludingwhat different kinds of the urban growth mode caused by the motive force, it analysed thecourse of the urban growth step by step. Aimming to make the analyse of this fractionmore thoroughly, it taken the urban growth of our country as an example to analyse everystep as a demonstration.The next, it researched the reasonableness of the urban growth.This part is asublimation of the analyse on urban growth and the growth mode, and is a emphases of thepaper too.according to the analyse,we known the different spacial modes showed in thecourse of urban growth had advantage and defect, and had each applicable object.When theurban growed to a stage that the recent spatial mode can not accelerate the urbandeveloping healthly,we should draw up correspond measure to guide urban spacialstructure developing more resonably. According to the research result, not only we canfind the channle and direction which are propitious to urban health development, but alsoavoid those disadvantages that could cause inverse urbanization coming into being.The final destination of the research is the result come out from the analyse can beapplied in actual,or can have significant guidance to practice.So, at the base of the research,the paper built the urban growth appraisal system. Following certain principles,consideringthe situation of urban development of past, now and future, it chose some appraisal index.Finally,taking the ShiJiazhuang urban space growth of HeBei province as a example,through investigating, using the land use data coming from remote sensing and research,it appraised the reasonableness of the ShiJiazhuang urban space growth, and get the resultthat the growth of ShiJiazhuang city is comparatively reasonable. It refered to the appraisalresult to provide advices for the development of ShiJiazhuang city in thefuture.Concurrently,it accomplished the whole process from a static one to a dynamic,toreasonablenes of dynamic and to empirical Investigation.
