Abstract

To rationally allocate farmland resources, and scientifically make farming industrial planning, we take Yizheng City in Jiangsu Province as the research object, and select 13 indicators. Based on Farmland Resources Management Information System in Yizheng City, we establish AHP model, and membership function model, for the evaluation of farmland suitability of rice. The results show that the farmland area in the highly suitable areas accounts for 10.2% of the total farmland area; the farmland area in the suitable areas accounts for 56.08% of the total farmland area; the farmland area in the marginally suitable areas accounts for 25.50% of the total farmland area; the farmland area in the unsuitable areas accounts for 8.22% of the total farmland area. There is significant positive correlation between the actual yield of rice surveyed and suitability index obtained through evaluation (R2=0.1964, 319 samples); the actual yield of rice in the highly suitable areas is higher than in the marginally suitable areas and suitable areas, and the rice yield is the lowest in the unsuitable areas.
