Abstract: The “hollowing” of rural settlements leads to changes in the structure and layout of rural land use. To study the spatial-temporal evolution of rural settlements from the perspective of rural revitalization, Jiutai district in Changchun was chosen as the research area, the land use data based on ArcGIS 10.6 and Fragstats 4.2 from 1990 to 2018 was adopted, and the methods including landscape pattern index, ANN index, and Voronoi diagram variation coefficient were used to analyze the characteristics of the spatial-temporal evolution of rural settlements in Jiutai district in the past 30 years. The results show thatOn the whole, the area of rural settlements has shrunk, and the average patch area has increased from 1990 to 218. On the patch scale, rural settlements are mainly distributed in a relatively regular manner, with low tortuous boundaries. The distribution of rural settlements generally shows agglomeration. The distribution of rural settlements in the towns and sub-districts is mostly random, and a few rural settlements are clustered. The distribution of rural settlements roughly shows the spatial distribution characteristics of “clustered in the middle and sparse around”. From 2000 to 2010, areas with high-density values shrank significantly. The center of gravity of rural settlements shifted to the center of Changchun. The research can provide a reference for the improvement and layout optimization of rural settlements, the promotion of the rational allocation of land resources, and the improvement of rural production and living spaces, to further realize rural revitalization and the development of urban-rural integration.
