Abstract
The aim of this study was to analyze the urbanization in Shanghai from 1990 to 2005. For this purpose, a time series in 1990, 2000 and 2005 of remote sensing images were collected and interpreted.Land Use/ Cover Change information (i.e. speed and direction and spatial variations) were extracted and the main driving factors were analyzed. Results showed that (1) Urbanization in Shanghai increased from 10.77% in 1990 to 32.96% in 2005 with a total increment value of 22.19%. Land use for city construction, industry and traffic contribute mostly to the change in Land Use/Cover Change, and the average growth rate was 0.43% during 1990-2005 and 1.99% during 2000-2005; (2) The direction in urbanization were different during 1990-2005, mainly expanding in Northeast, Southeast and Southwest. (3) Spatial variations were observed in the urbanization during 1990-2005, and were mainly distributed in the city center (i.e. 0-12 km) in 1990, and then extended to 20 km in 2000 and 40 km in 2005. (4) Economic development and population growth were the main driving factors accounting for the urbanization in Shanghai during 1990-2005.
