Research on the village layout optimization in China's developed areas based on daily life circles.

Public service facilities are the basic material carrier of social services. It is of great significance for the operation of social justice and the improvement of residents' wellbeing. In the process of rapid urbanization, the demand for traffic convenience and diversity of public service facilities in rural areas has been further improved. Since the sudden outbreak of the COVID-19 epidemic, it is more necessary to meet the public service needs of human daily life within a certain space. The huge gap between urban and rural infrastructures, human living conditions, and supporting public services such as education, health, and culture has become a key bottleneck constraining the integration of urban and rural areas. It is appropriate to focus on the requirements for the construction of daily life circles and prioritize the satisfaction of villagers' increasing demand for public services in regions characterized by high levels of urban-rural integration. The behavior preference of public service facilities significantly affects the choice of residential areas. The existing research on village layout optimization focused on the spatial pattern, landscape morphology, influencing factors, and other contents. To some extent, the preference for equalization of public services in the context of urban-rural integration has been ignored. Uneven distribution and low utilization of public service facilities in villages resulted in an inability to adapt spatially and functionally in response to the renewal of urban-rural relations. Taking a highly developed urban and rural integration area named Wuxi City of Jiangsu Province in China as an example, this paper combines the current situation of public service facility allocation and the transport situation of residents in rural areas to build a life-circle system of different levels. On this basis, combined with the optimization goal of public service facilities and the constraints of agglomeration coverage, we try to determine the village layout optimization scheme under the construction of both the daily life circle and location-allocation model. The study can effectively adjust the allocation of public resources in rural areas and solve the problems of irrational village layout leading to long travel distances. It can also serve as a reference for improving the situation of lagging rural public service functions and promoting urban-rural equalization.
