By Sustain Of Spatial Analyse Investigate Model Of Urbanizational Trend Of City ChangChun

Geographic Information System, as a part of information network ,can not only storage,inquire, search, but prior simulate, evaluate,forecast. It becomes capacity facility ofmodernization manage, programming, and decision-making, Though controllinghuman-moving, matter-moving, improve ground and asset increment capability ,ameliorateinvest circumstance, realize society and economy consist development.With the decelopment of figure and information,GIS is applianced every domainincreasingly. Racently, studying citilization combined with GIS gather and deeper.The text exercise GIS space analysis technology and regress, study the data ofrecent 10 years in Changchun , base on the data of population ,economy, zoology, communityfrom 1993-2002 Changchun villages and towms .On base of analyzing citilazationfactor,impetus mechanism,appraise,pivot study dynamic character—curret model.Part1: foreword.Author analyse exoterica and technology, in point view of GIStechnique, city geographical. Open out theoretics sense and realism sense. Confirmconsidering way though research actuality of correlation domanial inside and outside.Part2: theoretics of citilazation current. In this part, the author discuss correlation theoryof citilazation,including influence factor, drive mechanism and citilazation level.On this base,refer study method of citilazation and GIS space analyse method.Part3: application of changchun citilazation current. Firstly, study the citilazationcurrent characteristic, then choose and construct changchun citilazation data-base.Afterchoose citilazation affect factor and analyse their interaction,put the current analyse andregression analyse into forecasting citilazation current ,gained the forecast result.Part4: conclusion and prospect . summarize study progeny and inspire,bring up futureresearch prospect.
