Late maturing citrus is one of the most well-known local specialty agricultural products in Dongpo District, Meishan City. In order to scientifically guide the local production and optimization layout of high-quality late maturing citrus, this paper evaluated the suitability of late maturing citrus in Dongpo District based on the soil data of 372 orchard plots from the 3^rd National Soil Survey in Dongpo District, in which the data of soil, terrain and climate were converted into fuzzy membership data, combined with analytic hierarchy process and fuzzy mathematics methods, the suitability evaluation model of late maturing citrus was constructed, which included 14 evaluation indicators of soil physicochemical properties, terrain and climatic conditions. Soil physical and chemical properties included pH, organic matter, bulk density, texture configuration, available phosphorus and potassium; topographic indicators included groundwater level, topographic location and slope; climatic conditions included effective accumulated temperature ≥10℃, annual sunshine, precipitation, extreme low temperature andoccurrence frequency of extreme low temperature. The results indicated that Dongpo District is very suitable for the production of high-quality late maturing citrus. Among the 3.47×10⁴ hm² of suitable orchard land in the entire area, the dominant area and suitable areas account for 16.00% and 79.97%, respectively. However, the limiting factors in different regions are different, and different combination measures should be taken to improve the suitability and ensure the production of high-quality citrus.
