| Abstract: | The case is chosen in Liling city which is one of the typical cities in the hilly areas of central southern china. The change of cultivated land of Liling city from 1949 to 2004 was analyzed by using statistical data. Then the driving forces of the cultivated land resource change of Liling in recent 15 years were studied by using principal component analysis. On the basis of this,the paper revealed that the economic development and social systematic pressure were dominical driving forces for changes of cultivated land. In the end,in response to different driving forces ,relevant countermeasures were brought forth. |
