Through the use of fuzzy evaluation, analytic hierarchy process and other mathematical theories to evaluate the cultivated land productivity in Zijin County, find out the cultivated land productivity and potential productivity in Zijin County. The cultivated land productivity in Zijin County is dominated by medium and low yield fields, of which, the area of high yield farmland accounts for 22.43% of the total cultivated land area, the middle farmland area accounts for 64.34% of the cultivated land area, the low yield farmland area accounts for 13.23% of the cultivated land area, The quality is better, is a medium level above.
