Abstract: In order to explore the spatial reconstruction strategy of rural settlements and help rural revitalization, We take Luojiang district of Deyang city as an example. Based on the remote sensing image data of GF-1 in 2018, we use object-oriented methods to extract settlement patch information, use nuclear density estimation to analyze the spatial distribution characteristics of rural settlements, and combine natural and socio-economic factors to construct the settlement land suitability evaluation system evaluates the existing rural settlements, and finally we propose a differentiated reconstruction strategy. The results show that:①The distribution of rural settlements presents the characteristics of "single-center multi-polar circle diffusion".② The suitability of settlement layout is generally high, with significant differences in suitability among different towns.③The layout of existing rural settlements tends to be higher-level suitable areas, and the more suitable the layout of towns and villages is more reasonable.④According to different agglomeration and suitability characteristics, the rural settlements in Luojiang district are divided into four types:agglomeration development type, construction promotion type, restricted coordination type, and ecological transformation type, and the direction of differentiation and reconstruction is discussed.
