In China, urbanization of agricultural land around city agglomerations increases rapidly. Rapid urbaniza-tion of agricultural land affects food supply, land value and ecological balance in the society. In China, the urban built-up area had increased by 40% from 1996 to 2003. This increase came predominantly from farmland surrounding thecities. How the ongoing urbanization of China affects its agricultural land is the focus of this paper. In current studies, wehave found that population density; urbanization degree and personal income are key factors that influence the urbaniza-tion process. Based on this, relation model has been established and to predict the general trends of the urban areaexpansion in China in 2020. In 2020, the constructed urban area of China would be increased by 1.3 times compared with2003. In 2020, this study anticipates the conversion of about 32,562 sq. km. agricultural land of China for urban use.
