Study on Fine Agricultural Regionalization of Spring Wheat in Tongren City Based on GIS Technology
[Objective]To optimize spring wheat planting structure in Tongren City,increase crop yield,and promote high-quality develop-ment of local agriculture.[Method]Based on the comprehensive consideration of local climate,soil and terrain factors,several regional factors affecting spring wheat growth were extracted,and different weights were assigned to each regional factor by analytic hierarchy process.[Re-sult]According to unsuitable,generally suitable,suitable and most suitable,the unsuitable area and suitable area are the largest,followed by the general suitable area,and the most suitable area is the smallest.The results showed that the most suitable areas and suitable areas of spring wheat planting in Tongren City were distributed in Huangnaihai Township,Nianduhu Township,Longwu Township,west of Baoan Township,northeast of Zamao Township and central area of Qukuhu Township.[Conclusion]The suitable planting area of spring wheat in Tongren City is mainly distributed in the north and southwest of the city,accounting for about 25%of the total area of the city.The existing spring wheat plant-ing areas in Tongren City are basically consistent with the suitable planting areas,including Huangnaihai Township,Nianduhu Township,west of Baoan Township,Longwu Township and Qukuhu Township.The area that needs to make proper adjustment is mainly Zamao Township,and the local agricultural department can appropriately expand the spring wheat planting area in the northeast of Zamao Township according to the actual situation.
