As the largest city in the country,metropolitan Shanghai is nowthe fastest growing area among all major Chinesecities with more than 13 million residents. Using the GIS-based land use data set of the year 1994 and combining gradientanalysis with landscape metrics, we attempted to quantify the spatial pattern of urbanization in the Shanghai metropolitanarea. The results of transect analysis with class-levelmetrics showed that the spatial pattern of urbanization could be quantifiedreliably using landscape metrics and different land use types exhibited distinctive, but not necessarily unique, spatial signatures.The results of transect a……
