Abstract: In the context of the national security strategy, the town (city) of the corps is ‘small city but not small’. It takes charge of the strategic mission entrusted by the state. This paper analyzes the characteristics and challenges of the corps town (city) during the transitional period from ‘Reclamation and Garrison’ to ‘Building-city and Garrison’, including ecological environmental protection, internal and external forces, military coordination, urban space, population size of urbans and towns, planning and construction, etc. The paper also points out the corps town (city) planning in the new times should be kept pace with times and overall planning. Based on the practical experiences of Cocodala, the paper prospects six strategies, including the development mode of green ecology, the industrial system of internal and external forces, the integration of corps cities and local cities in a winwin cooperation, the relatively balanced space pattern, the planning concept of ‘human-oriented orientation’, and the action framework of time-sharing division, hoping to provide reference for other new corps town (city) planning.
