| Abstract: | In this article , illustrated by the example of Changqing , a county of Jinan city , Shandong province, land fertility and cultivated land potential productivity are carefully studied . At first, multiple factors influencing land fertility are expounded , and the GIS and RS based synthetically evaluation is discussed .Then using the mechanism methodology and computing models ,five kinds of cultivated land potential productivity are computed and the results are precisely expressed as grid map that the size of it's single grid unit is 900 square meters. |

| Keywords: | Land fertility Index of synthetically evaluation Cultivated land potential productivity |
