Under the background of high quality economic development, the purpose of grasping the form of cultivated land use(function)is to provide the basis for deepening the multifunctional management and sustainable use of cultivated land. From the perspective of structure analysis, we analyzed the spatial scale characteristics of cultivated land use function transformation in Jialing River Basin of Sichuan Province from 2011 to 2018 by mathematical quantitative comprehensive analysis method, and explored its driving mechanism. The results show that:(1)the cultivated land use function in Jialing River Basin had realized the transformation from social ecological type to economic social type, and was moving towards economic ecological type;(2)the cultivated land use function in the three major river basins showed that Guangyuan River Basin basically had realized the transformation from social ecological type to economic social type, Nanchong River Basin gradually had realized the transformation from economic social type to economic ecological type, and Guangan River Basin had realized from social ecological type to economic social type;(3)in the 16 counties(cities), the cultivated land use function generally showed the transformation from social ecological type to economic social type in northwest, northeast and southeast regions, and southwest regions had two forms that were economic social type and transition from economic social type to ecological economic type;(4)the structure of cultivated land use was optimized at different spatial scales in the Jialing River Basin, and the cultivated land use function had a spatial scale effect and was changing to a more coordinated function;(5)the driving mechanism of cultivated land use function in the Jialing River Basin was that the urbanization process accelerated the manifestation of cultivated land market value, coupled with the decline of agricultural comparative benefits, induced the substitution of agricultural production structure, led to the change of cultivated land use structure, and drove the transformation of cultivated land use function form, and the urbanization development was the continuous driving force, agricultural income was an important factor. To sum up, suggestions were put forward, including strengthen cultivated land planning and control based on the background of cultivated land resources, coordinate the interests of the main body to construct the multi-functional coordination mechanism of cultivated land, deepen the agricultural industrial system to ensure the high-quality and efficient use of cultivated land, and strengthen the ecological construction of cultivated land to promote the sustainable use of cultivated land.
