Study on the Farmland Evaluation Index System through the Construction of Mathematical Models and Big Data

Abstract Basic farmland is the essence of cultivated land. To completely solve China’s food security problems and achieve stable growth of agricultural production in China, it is one of the most effective ways to build high-standard basic farmland. Therefore, this paper evaluates the high standard basic farmland. This paper evaluates the natural quality of basic farmland through the construction of mathematical models. The total cultivated land area in the hilly area of Faku County is 153061.02 hm2, while the natural quality score of cultivated land in the hilly area of Faku County is between 51 and 86. Among the equal-valued intervals, the maximum cultivated land area between ≥60-70 is 129110.25 hm2, accounting for 84.35% of the total cultivated land in the hilly area of the county, followed by the area between ≥70-80, which is 9069.44 hm2. The total area of cultivated land in the hilly area of the county is 5.92%, followed by the interval of ≥ 80 points, <60 interval, the area is 8095.61 hm2, and the ratio of 6787.72 hm2 accounts for 5.29% and 4.43% of the total cultivated land in the hilly area of the county. In general, the natural quality of cultivated land in the hilly area of Faku County is moderate.
