Abstract:

In the process of desingating prime farmland, such problems exist as determining prime farmland subjectively, catering to economic development too much and neglecting the quality request for farmland. To make the designation of prime farmland more scientific, reasonable and efficient, this study builds the decision-making model of determing prime farmland by computing the value of each factor, based on consideration of the quality of farmland, land fertility and connectivity and combined with the location of farmland. Furthermore, this model is verified in Dujiangyan city, where significant differences exist in landforms such as plains, hills and mountains as well as land quality and regional conditions. The results show that this method is more scientific and reasonable, and can avoid the subjective impact in the process of land planning.
