Abstract: China has experienced rapid urbanization, causing dramatic changes to the patterns of urban and rural land use relationships. This paper analyzes the spatiotemporal characteristics of rural settlements in the middle reaches of the Yangtze River region (MRYRR) using remote sensing monitoring data from 1990 to 2020 and reveals the influencing factors of spatiotemporal changes. The research found that (1) the overall increase in the quantity of rural settlements in the MRYRR between 1990 and 2020 was 504.70 km 2 . The area of transfer of other land use types to rural settlement was 1382.57 km 2 , of which 78.55% came from arable land and 16.62% came from forests; the area of rural settlement transfer to other land use types was 867.24 km 2 , of which 66.27% was reclaimed as arable land and 8.48% was transferred into urban built-ups. Changes in different stages and regions are diversified. (2) The spatial layout of rural settlements showed no significant differences in the MRYRR between 1990 and 2020, with a cluster distribution of “five main nuclei and many secondary nuclei” and a spatial distribution of “gathering in the north and east, while scattered in the south and west”. (3) The level of fragmentation of rural settlements in the MRYRR has greatly decreased since 1990, with the average patch size expanding significantly. The patch complexity of rural settlements fluctuated moderately, but the connectivity between patches continued to increase, and their distribution became more clustered. (4) Social and economic factors, including rural electricity consumption, the output value of the primary industry, net income per rural resident, urbanization rate, and the effective irrigated area, most strongly impacted the changes in rural settlements in the MRYRR. The research can be utilized as a guide for reconstructing the pattern of rural land use to promote sustainable rural revitalization.
