| Abstract: | Based on the historical data and the current data of the cultivated -land which obtained in 1985 from the 2nd National Soil Survey and in 2005 from the project of ＇ Soil Test and Formula Fertilization＇ , the wheat planting suitability of cultivated - land in Guangde County was assessed quantitatively with ArcGIS and CLRMIS （ Cultivated Land Resource Management Information System at County Scale）. The results showed that the most suitable, suitable, reluctant and not- suitable planting grade of cultivated land are 7400hm^2, 31150hm^2, 26700hm^2 and 9750hm^2, respectively; which constitute of 9. 9% , 41.5%, 35.6% and 13.0% of the total area of the cultivated land, respectively. |
