Abstract:Improving the urbanization strategy and making the city a space for the people's high-quality life is the new requirement put forward by General Secretary Xi Jinping for urban development. To fulfill this requirement, it is needed to study and understand in-depth consideration of urban development issues. This work studies urban issues from the national conditions such as urban morphology, population distribution, population mobility, and flow of peasant workers. Focusing on the overall requirement of respecting regularity, this study considers the connotation of urbanization and socialist modernized cities in the era of ecological civilization. Reviewing the theoretical basis of urban science proposed by Qian Xuesen, this study puts forward the guiding principles for the current research on urban science, and the main points and contents for thinking based on a new stage, implementing new ideas, and constructing a new pattern.
