Abstract: This paper takes the Yangtze River Delta——a group of fast developing cities as an example to analyzes the land use change and driving forces during the urbanization process. By analysing the rate of each type of land and the factor analysis, the major change in this area is the rate increase of constructed land and decrease of cultivated land. In this respect, driving force factor system is formed and a regression model has been constructed. By related analysis and principle analysis,It is concluded that the major driving forces are the population increase and urbanization, the increase of economic output and the urbanization of labors. However, the major driving force changes as the social economy development and land use characteristics vary. The urbanization and the tertiary industry development become stronger to drive the land use change in the city region of the Yangtze River Delta, while the growth of total economy is a weak driving force.

Key words: the Yangtze River Delta, city region, the change of land use, driving force
