Mountainous area account for 94% in Yunnan, China. Among them, cultivated land only 16.20%. In order to classify and protect cultivated land contiguous, take Huaping , a typical mountainous area as an example, and integrates the entropy weight method, TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) and spatial autocorrelation method to construct a zoning method based on CLQE (Cultivated Land Quality Evaluation). The results showed that the CLQE was divided into five grades. Class 1 and Class 2 was higher, respectively accounting for 24.98% and 29.98% of the total cultivated land area, Class 3 and Class 4 was accounting for 23.17% and 13.76%, Class 5 was the worst, accounting for 8.11%. In terms of layout, it can be divided into 4 areas, key protected areas are distributed in Class 1 and 2, accounting for 52.52% of the total, suitable adjustment areas are distributed in Class 1, 2 and 3, accounting for 9.02%, key control areas are distributed in Class 3 and 4, accounting for 25.41%, reduce reserved areas are distributed in Class 4 and 5, accounting for 13.05%. The results are consistent with the actual situation, and provide a feasible method for cultivated land classification and zoning protection.
