Data of cultivated land in Jiangsu Province from 1996 to 2004 are analyzed by statistics.The results showed that the change of the cultivated land in the research region was descending and the descending rate was increasing from the North to the South.This paper mainly focuses on the corresponding type of cultivated land use to different stages and state of industrialization and urbanization respectively and the regularity between them.In order to determine the relationship between the cultivated land and the stage of industrialization and urbanization,we try to analyze the different stage of industrialization and urbanization in each cities and the change rate of the cultivated land according to comparison of each other.The study showed that there were obvious discrepancies of the cultivated land change in the different stage of cities' industrialization and urbanization.The cultivated land's descending rate takes on the drastic change,rapid change,and slow change(or steady change)in the upper-stage,medium-stage,and initial-stage of the industrialization respectively.In the same way,there are different changes(drastic change,rapid change,and slow change or steady change)of cultivated land in the initial-stage,accelerating-stage,and ending-stage of urbanization.At last,industrialization and urbanization index were selected to determine the extent which related with the change of cultivated land.The two coupling coefficients and cultivated land coefficient showed a strong consistency through a comparison.The descending rate of cultivated land was accelerating with the development of industrialization,and the area of the cultivated land was decreasing with the advancing of urbanization.This result showed that the development of industrialization at present mainly benefits from the descending of the cultivated land,and the development of urbanization result in the decreasing of cultivated land,but the change between two coefficients is not happened simultaneously.
