Regional cultivated land quality evaluation method and system

The invention discloses a regional cultivated land quality evaluation method and system, and belongs to the field of agricultural engineering. The method comprises the following steps: S1, obtaining and numbering a cultivated land distribution diagram of a certain region; S2, acquiring the cultivated land area; S3, calculating the cultivated land soil fertility evaluation grade in the area; S4, calculating cultivated land distribution dispersion in the area; S5, calculating a planting favorable degree index of the area; S6, calculating score matrixes of different dimensions; and S7, calculating a total cultivated land quality evaluation index. The quality of cultivated land in different areas can be visually compared according to a unified standard; and by standardizing the calculation process and defining the processing method, the cultivated land quality acquisition data is normalized and standardized, scientific researchers can quickly program and process cultivated land evaluation data, and the obtained r
