Analysis And Application On The Distribution Rule Of Country Resident's Resettlement And Reconstruction In The Three Gorges Reservoir Area

The development of Geographical Information System has provided technical means for developing and analysis of settlement geography,and has changed old qualitative depiction for the quantitative analysis. In view of the resettlement'plan actual demand application and guided by settlement geography, this paper analysises quantitatively the residents spatial distribution type and the rule with the use of spatital analysis technology and statistical analysis model, and also discusses the fingings application. Moreover, unifying the population spatial model, this paper has carried on the confirmation to the residents spatial distribution rule of reservoir area. Firstly, this paper take the Three Gorges reservoir area ZiGui County as an example,has analysised the residents spatial distribution congregate type and concluded the decided factor is landform and status of economical development. Secondly,using statistics and GIS technology,such as overlay,buffer, DEM analysis, studies quantitatively the relation between residents distribution and influencing factors, concluded regression model of the influencing factors, and finding residents spatial distribution rule. Lastly, takeing inhabitant as instruction factor , the paper puts forward population spatial model, discusses the fingings application, and also validates the residents spatial distribution rule.
