Abstract: Based on the perspective of urban and rural heterogeneity, this paper evaluated the difference of microsubjects supply and demand characteristics of farmland multifunction and their willingness to improve farmland multifunction, and analyzed the influencing factors of the difference between supply and demand of farmland multifunction, and provided an effective path for establishing the manifestation mechanism of cultivated land multifunctional value. According to the actual differences of regional development, this article selected the counties with production function or ecological function as the leading function as the research area. A questionnaire survey method was adopted to collect 146 valid questionnaires, and finally, the Tobit model was used to study the influencing factors of farmland multifunctional improvement intention. The results showed that there were differences between urban and rural residents in their cognition of multifunction supply and demand of cultivated land and their willingness to improve. Farmers believed that the supply degree of economic function of cultivated land in their region was the lowest, and the recognition degree was only 11.76%, but the demand degree of landscape cultural function was as high as 23.39%.The cognition of respondents in the production function leading area on the supply level of multi-functional cultivated land is consistent with the positioning of the local main function zoning, and the various functions of cultivated land have basically achieved regional supply and demand balance, while the cognition of urban and rural residents on the supply level of multifunctional cultivated land in the ecological function leading area and their willingness to improve are different, and farmers' recognition of the supply level of cultivated land landscape cultural function is the highest, up to 35%. There are different levels of correlations between the different characteristics of micro subjects and the perceived degree of the willingness to improve the multi-function of cultivated land. The results of this study can provide scientific basis for the future implementation of diversified management of cultivated land and sustainable use of cultivated land.
