As a transitional zone between urban and rural areas, the peri-urban areas are the areas with the most intense urban expansion and the most frequent spatial reconfiguration, and in this context, it is particularly important to reveal the evolution pattern of rural settlements in the peri-urban areas to provide reference for the rearrangement of rural settlements. The study takes five townships in the urban suburbs, and explores the scale, shape, spatial layout, and spatial characteristics of the urban suburbs of Hefei from 1980 to 2030 under the influence of urban-lake symbiosis based on spatial mathematical analysis and geographical simulation software. The study shows that: (1) the overall layout of rural settlements in the study area is randomly distributed due to the hilly terrain, but in small areas there is a high and low clustering phenomenon, and the spatial density shows the distribution characteristics of "high in the east and low in the west"; (2) since the reform and opening up, there are large spatial differences in the scale of rural settlements in the study area. (3) Different development scenarios have a strong impact on the future spatial pattern of rural settlement land use within the study area, which is a strong reflection of policy.
作为城乡之间的过渡地带，城市边缘区是城市扩张最剧烈、空间重构最频繁的区域，在这种背景下，揭示城市边缘区农村居民点的演变规律，对农村居民点的再布局具有重要的参考意义。本研究以合肥市五个乡镇为例，运用空间数理分析和地理模拟软件，基于城市-湖泊共生的影响，探讨了 1980-2030 年合肥市城市边缘区农村居民点的规模、形态、空间布局和空间特征。研究表明：（1）研究区农村居民点整体布局由于地形起伏呈随机分布，但在小范围内存在高值和低值聚类现象，空间密度呈现“东高西低”的分布特征；（2）改革开放以来，研究区农村居民点的规模存在较大的空间差异。（3）不同的发展情景对研究区内农村居民点土地利用的未来空间格局有较强的影响，这是政策的强烈反映。
