The research on rural settlement has achieved rich results, but there are relatively few studies on rural settlements in megacities. This paper uses Shanghai's multi-period land survey and remote sensing data to analyze the changes in the scale, shape and layout of rural construction land from the perspective of urban-rural relations, and reveals the spatial evolution mechanism of rural settlements in megacities. The study found that: (1) Before 2000, the urban and rural construction land grew slowly, and did not interfere with each other. The rural settlements showed the characteristics of ‘large dispersion and small concentration’. (2) In 2000-2009, urban expansion accelerated, engulfing rural space, and the area of rural settlements rapidly decreased, but still maintained the characteristics of “dispersion”. (3) After 2009, the boundary of urban development is locked. Under the background of the increase or decrease of construction land, the scattered and inefficient rural construction land is reclaimed, and the spatial agglomeration of rural settlement is strengthened, reflecting the characteristics of ‘large concentration and small dispersion’. This study provides the possibility to supplement the spatial evolution analysis method of rural settlements in megacities.
