The urban concentrated area is a form of regional organization in the advanced stage of urbanization. It is benefit for clearing national development framework and promoting regional integration to divide and identify the urban concentrated area spatially. Based on the existing research results, according to the level and stage of China's urbanization, this article defines the space identification standards of urban concentrated areas in China, including such aspects as the core city, standard city, other small cities and towns, and boundary identification, then divide Chinese cities into 15 typical urban concentrated areas and 8 quasi-urban concentrated areas based on the traffic accessibility. They present a spatial pattern of "three vertical and two horizontal distributions", which construct a national system of urban concentrated areas. Compared with the main function areas of the national plans, the proposed program of urban concentrated areas is consistent with the strategy pattern of urbanization in the national plans of main function areas on the whole. Under the guidance of the strategy of the national main function areas, the urban concentrated areas should develop in the light of the positions and goals in the plans to select the right path and direction.
