Research of Suzhou City’s Expansion Changes Based on Multi-Temporal TM Images

Abstract:

Taking the Landsat TM/ETM+ images of Suzhou City in 1995 and 2003 as data resource, the expand changes of the construction land were researched. Computer supervised classification and GIS spatial analysis methods were used to extract the Suzhou City construction land information, and the construction land expansion distribution map of Suzhou City from 1995 to 2003 was obtained. Last urban expansion speed, compactness and fractal dimension index were combined to analyze the Suzhou City’s expansion change characteristics. The results showed that, from 1995 to 2003 Suzhou city in a stage of rapid development of urban expansion, the spatial form is increasing complexity, the expand trend is for ancient city center to radiation spread all around, among them with the eastern and northern expansion is most obvious.
