Spatial-temporal pattern and transfer path of cultivated land use transition from the perspective of human-land-industry coordinated development: A case study of Shanghai, Zhejiang and Fujian

Based on the concept of rural revitalization and development and the concept of "people land industry" coordinated development, this paper constructs evaluation indexes to measure the cultivated land use in Shanghai,Zhejiang and Fujian for the time period from 2005 to 2020. Coupling degree analysis, spatial autocorrelation analysis and the method of standard deviation ellipse are applied to analyze the cultivated land use index and explore the temporal and spatial distribution and transfer path of cultivated land use transformation. The results show that:（1） From 2005 to 2020, the cultivated land use transformation index of all regions in the study area showed a downward trend,and the difference of cultivated land use was decreasing.（2） The coupling degree of spatial transformation and functional transformation in the study area is stable at 0.8～0.9, showing perfect coordination. However, the spatial transformation of cultivated land use is mainly concentrated in the north of the study area, and the spatial t
