| Abstract: |
| With the support of GIS and computer technology， this paper evaluated the farmland productivity by a- dopting Analytical Hierarchy Program， based on the data of the second soil survey and soil testing and formulated fertilization in Datong district. The results showed that the farmland productivity in Datong district was divided into five ranks and each rank from best to worst occupied 16.2%、41.6%、28.6%、9.1% and 4.5% of farmlands. Finally， some improvement land use measures of cultivated lands were put forward. |
