Abstract

Suzhou, Wuxi and Changzhou are located in Yangtze River delta which is a hot spot for socio-economic development in China. With the rapid economy development, the urbanization of those three cities keeps a high level. Growth of urban land use is an important feature of the procession of urbanization. The urban land use growth of Suzhou, Wuxi and Changzhou during the year of 1979-2001 was studied on the base of RS and GIS methods. The growth area of urban land use and the features of spatial pattern of urban land use growth were analyzed. The study shows that since the opening and reforming of china, the urban land use of these three cities has a significant growth; the total area of urban land use in 2001 is 2.7 times bigger than that in 1979, while the rate of land use change is 7.7% and the growth intensity index is 1.08%. Local nature, traffic, economy condition and policy decision making dominate the direction of land use growth. During 1979-1991, extending directions are accordant with main rivers and major roads. During 1991-2001, extending direction has a significant tend towards the development zone.
