Abstract: It is an important content of the new urbanization era to construct the urban pattern of coordinated development between large-medium-small cities and small towns. The development foundation of small towns in the central region is historically backward, and small towns face new opportunities in spatial development. The spatial pattern of small towns in Hunan Province presents four characteristics:obvious hierarchical scale pattern, strong spatial clustering along traffic trunk lines, concentrated distribution of characteristic small towns, and clear ecological spatial pattern. In combination with the new requirements of territorial spatial planning, the spatial planning system of small towns in Hunan Province should be optimized from three aspects, including optimizing the spatial pattern of regional small towns' scale, guiding the characteristic industry space in different layers and guiding the ecological space with dual objectives.
