This resulted substantial transformation cultivated land However, efficiency occupation land, its regional differences, urban-rural disparity remain unclear. Therefore, using population use data, we measured occupied urban rural during 1990–2020 proposing absolute, differential, relative evaluation methods. Our study revealed that area is 22.4% higher than areas was areas. Spatially, land-occupied shows a pattern high southeast low northwest. increases with increasing size. Thus, improve strict control on should be loosened, particularly for larger cities, inefficient tightened.
