Abstract: Purpose In order to alleviate the sharpness of the contradiction between human and land in China, the dynamic balance of cultivated land is realized in essence. Taking Dapo Township of Zhanyi County as an example, through field research and combining the results of low-yield field reconstruction projects in similar areas, on the mountain The evaluation index system for low- and medium-yield fields in Qiu District will be further explored and improved. MethodThis study will use the analytic hierarchy process to calculate the comprehensive weights of various evaluation indicators from the three aspects of soil conditions, climatic and geomorphological conditions and social conditions, as well as the 11 evaluation indicators selected by the optimization, and build a comprehensive evaluation index for the transformation of low- and medium-yield fields in hilly areas system.Result The results show that the weights of soil conditions, climatic and geomorphological conditions and social conditions in the constructed evaluation index system are 0.428, 0.428 and 0.144, respectively. Among them, soil texture index (0.15) and soil layer thickness (0.15) were the most influential in soil condition index. The most influential rate in climate and geomorphological conditions was slope (0.261). The most influential factor in social conditions was economic input (0.046). Conclusion Through the construction of AHP model of analytic hierarchy, it can provide a scientific and reasonable reference for the transformation of low-yield fields in similar areas.
