The Landsat satellite image of Liuyang City was selected in June 2018, and the land use landscape type map was generated based on RS and GIS technology. The landscape index was calculated by the FRAGSTATS to analyse the landscape pattern of urban land use in Hunan hilly areas, and the minimum cumulative distance model was used to construct the urban ecological pattern. The results showed that: ①The most dominant landscape types in the city area were forest lands with high degree of aggregation and cluster distribution. The fragmentation of landscape types in urban areas was obvious, especially the grassland fragmentation. ②There are few landscape types in the city area, and there are obvious dominant landscapes. ③The article builds an ecological security pattern by searching for ecological sources, corridors and nodes, and guarantees the ecological security of hilly urban cities.
