Abstract:

The rapid social and economic development led to the gradual emergence of the multi-functionality of cultivated land. However, existing studies mainly evaluate the function of cultivated land from the perspective of a single function, while the comprehensive investigation of the production-living-ecological function of cultivated land based on elements still remained in the exploratory stage. Therefore, the connotations of cultivated land, cultivated land function, and cultivated land production-living-ecological function were defined based on the systematic analysis of the cultivated land system as well as its elements, and the evaluation framework and the zoning conceptual model of the production-living-ecological function of cultivated land were theoretically constructed. The empirical results showed that the production and living functions of more than 80% of cultivated land and the ecological function of more than 60% of cultivated land were medium or above, which indicated that the degree of development and utilization of cultivated land in Nan′an City was at a high level, and there might be overlap, occupation, and agglomeration between different functions. Under the influence of natural production potential and geographical location conditions, arable land reach level and cultivated land dependence, ecological base condition and ecological protection policy, the production-living-ecological function of cultivated land showed evident regional convergence. About 50% of the cultivated land in Nan′an City had a single function, indicating that the comprehensive level of cultivated land function was still low. The area proportions of function combination models indicated that although cultivated land still provided important food security and social security, the development of cultivated land had been endangering regional ecological security. Therefore, it is necessary to take differentiated utilization, protection, and management strategies according to the spatial distribution, combination pattern, and function intensity of cultivated land functional zoning. Our study could provide theoretical and methodological support for the multifunctional utilization and management of cultivated land under the background of rural revitalization strategy and national spatial planning system construction.
