Abstract:: A decision-making model was built for selecting cultivated land into prime farmland by GIS technology and entropy weighting ideal point. The results revealed that: (1) system of comprehensive quality of cultivated land evaluation should not only consider the quality of cultivated land, but also should take into the cultivated land occupation which aims to meet the socio-economic development and biodiversity protection; (2) priority sort and partition of selecting cultivated land into prime farmland was based on the approach degree calculation, it was divided into optimal interval (0.640 5, 0.916 8］, relatively optimal interval(0.526 6, 0.640 5］, general interval (0.429 5, 0.526 6］, poor range (0.330 2, 0.4295］ and the worst interval [0.000 0, 0.330 2], which accounted for 12.60%, 33.33%, 29.90%, 10.73%, 13.45% of the total cultivated land, respectively; (3)the results of comprehensive quality evaluation and priority sort for cultivated land showed that about 13.45% of cultivated land was in poor range and was unsuitable to be selected as prime farmland, it was not reasonable for higher authorities issued the quantity of prime farmland to Ledong county.
