| Abstract: |
| On the basis of clarifying negative and positive impacts of cultivated land fragmentation (CLF), the evaluation system of CLF was constructed, and the method of solving the CLF phenomenon was explored with the concept of differentiation according to local conditions. Taking the status quo of cultivated land use in Shaanxi Province in 2020 as an example, we constructed a 3D Rubik’s cube model of the degree of CLF in Shaanxi Province from three aspects, namely the natural resource endowment of cultivated land, the degree of spatial aggregation, and the degree of ease of use to explore the characteristics of the spatial differentiation of its CLF and put forward a strategic plan for the improvement of CLF. The results showed that the CLF index (CLFI) in Shaanxi Province generally presented a spatial characteristic of low in the middle and high in the north and south, with the maximum value of CLFI at 0.796, the minimum value at 0.020, and the mean value at 0.217, and the high values were concentrated in the Qinba mountainous area at the junction of southern Shaanxi and Guanzhong and the eastern area of northern Shaanxi. Based on the CLF characteristics and influencing factors such as agricultural cultivation diversity, regional economic level and three attribute characteristics of arable land resources, an optimized zoning plan for CLF in Shaanxi Province has been proposed, including six types of township\|level guiding zones, namely, maintenance and enhancement zone, intensification and consolidation zone, facility optimization zone, resource renovation zone, comprehensive enhancement zone, and comprehensive remediation zone. The policy inclination zone based on regional socio\|economic indexes. The enhanced rectification zone, resource tendency zone, and resource adaptation zone were combined, considering the characteristics of the results from the two types of zoning. The characteristics of the two types of zoning results suggest the main land consolidation directions and key issues in different areas. |
