Abstract: The urbanization of China has entered the middle and late stage, and the connotation of the people-centered urbanization needs to be further enriched and refined. The land spatial planning is the key to the practice of the new-type urbanization and ecological civilization construction. This paper proposes that the improvement of well-being of residents is the core of the people-centered urbanization. It sorts out relevant domestic and foreign studies on the connotation of well-being, summarizes the subjective and objective measure index systems and methods of well-being, and examines the factors influencing well-being and happiness of residents. In this study, we draw on the experience of foreign spatial planning and take the improvement of the well-being of urban and rural residents as one of the guiding principles for the compilation of land spatial planning. In the process of the practice of land spatial planning, it is necessary to focus on public health, disaster risk assessment system and construction of urban resilience, optimization of "production-living-ecological" spaces, community living spatial planning, fine-scale management, and big data and intelligent decision-making system. Urbanization is the indispensable important component of national spatial planning, and the establishment of national spatial planning promotes the high-quality development of new-type urbanization and the well-being of urban-rural residents. So, we should show great concern on urban scale hierarchy structure, the pattern of population flow network, peri-urbanization and local urbanization, basic allocation and equalization of public service of urban and rural areas, the impacts of climate change and urban disaster risk management, and the basic research of the new-type urbanization, such as the evolution of man-land relationship in the rapid urbanization.

Key words: well-being, new-type urbanization, middle and late stage, happiness, Beautiful China, land spatial planning
