Research of Urban Land Use Pattern Evolution by RS and GIS

GAO Song-feng et al (College of Earth Science,China University of Geosciences,Wuhan,Hubei 430074)  
With Yiwu city's remote sensing images(Landsat TM) in 1986,1991,1997 and 2002,the urban pattern evolution model was established on base of RD and DIS technique to analyze quantitatively the correlation of the urban population and economical development to urban land use pattern evolution.It is found that there is a strong linear correlation between the population and urban land use pattern evolution with the correlation coefficient of 0.993?6,suggesting that the population increase is the most direct power for urban land use pattern evolution. There is a high correlation between the GDP and urban land use pattern evolution with the correlation coefficient of 0.931 0,indicating that the economical increase also is a basic power of urban land use pattern evolution.Qualitative analysis on the effect traffic condition shows that the traffic condition also has an important effect on urban land use pattern evolution.The evolutional course and law of Yiwu urban land use pattern evolution is also discussed,which provide the foundation for urban land layout.
