China is facing the dual challenges of urbanization and motorization（Jing, 2008）. The poorly organized urban centers and traditional residential planning are unable to meet the increasingly diverse demand of people. To solve these problems, the TOD model and the emerging community living circle are being favored by policy makers. Promoting urban construction based on the land development model of large-capacity rail transit station becomes a common understanding in many cities (Xuewu & Meng, 2018). However, faced with chaotic urban layout, mixed functions, and complicated land use, the new modes of transportation (rail) and the built-up areas (communities) create incompatibility. The issue of coordinated development of rail stations and communities is receiving increasing attention. Simultaneously, the uneven distribution of public facilities prompts the community living circle to emerge as a means of planning innovation. However, the theoretical division of the station influencing realm and community living circle is not applicable to mountain cities. In the context of complex mountain terrain, the way in which the two describe the space with a fixed distance as the radius is inconsistent with actual experience of people. So, this paper redefines the station influencing realm and community living circle, and delimits the radiation range of the two with the walking time of 15 minutes. Moreover, the connection area affected by both can reflect the spatial coupling and accessibility of the two spaces. At the same time, the connection area has low coupling degree and poor space quality in the mountain city. Therefore, the design strategy for the connection space of mountain cities needs to be updated and optimized. This paper will review the literature on TOD models and their associated station influencing realm and link them to residential district planning and start-up concept of community living circle to better explore their dynamic relationships and build a set of operational models and assessment systems, achieving a balance between transportation, high density and high-quality space experience.

Although the benefit of agglomeration has been hugely emphasized by the central government which led to the majority of amenities and services are only in cities and the household-registration system (Hukou) equipped the city with more advantages, the exclusively focus on “megacity-making” eventually leads tothe mega-city problems, environmental deterioration and the urban-rural disparity. In the 30 years since the reform and opening up, the rapid urbanization has brought many urban problems to China, such as the widening gap between urban and rural areas and the worsening environment.Urbanization is still in progress in China, with another 300 million people expected to become urban in the next decade. Based on the studies of the Kunming peri-urban area, this project will analyze the competitive advantages and disadvantages of peri-urban agriculture development in Kunming, and reveals that the rural industry transformation is the development trend of peri-urban village reinvention from the perspective of realizaing the diversified agricultural values - economy, ecology and society values. This project will also discusse the spatial planning strategy of peri-urban villages under the guidance of industry agglomeration and knowledge economy, forms the benign growth boundary between urban and rural areas by constructing the multi-functional industrial-space system, and finally realizes the urban-rural coordinating development with different characteristics respectively.
