| 摘 要： | As one of the developing countries China has an arable land per capita far below the world‘s average level.With a high-density population an the quick development of economy and urbaniztion,the Yangtze River Delta shows the typical characteristics of land use in developed regions of China,which are:high land reclamation rate and low arable land per capita;intensive land use and high output value;and rapid increasing of construction land area and fast diminishing of arable land.The analysis indicates that the process of the arable land changes in the Yangtze River Delta could be divided into four different change stages over the past 50 years.

| Abstract: | As one of the developing countries China has an arable land per capita far below the world's average level. With a high-density population and the quick development of economy and urbanization, the Yangtze River Delta shows the typical characteristics of land use in developed regions of China, which are: high land reclamation rate and low arable land per capita; intensive land use and high output value; and rapid increasing of construction land area and fast diminishing of arable lands. The analysis indicates that the process of the arable land changes in the Yangtze River Delta could be divided into four different change stages over the past 50 years. |
