Zizania latifolia is a characteristic agricultural product of Jinyun County with a long cultivation history.Based on findings from the national soil census and other surveys,data on climate,topography,soil,and infrastructure were converted into GIS spatial data.An evaluation index system comprising 12 influencing factors was constructed using the analytic hierarchy process(AHP).Membership values were assigned to each evaluation indicator,and the comprehensive index method was employed to assess the suitability grades for cultivation.The results showed that the total areas classified as highly suitable,moderately suitable,and basically suitable for Zizania latifolia cultivation in Jinyun County were 1 074.3 km2,accounting for 83.00％of the county's total suitable cultivated land areas.The current Zizania latifolia cultivation areas were generally consistent with the highly or moderately suitable zones,validating the scientific nature of the suitability evaluation method and its results.These findings provide a reference for optimizing the cultivation layout of Zizania latifolia in Jinyun County and promoting the sustainable development of the local specialty agricultural industry.
