As the forerunner of the revitalization of public spaces in urban blocks，Barcelona adopted the planning scheme of Cedar’s urban expansion area in the middle of the 19th century，which laid the grid plane of the chessboard shape of the whole city；in the early 21st century，Barcelona innovatively proposed the concept of “innovative district”；and recently，the new concept of “superblock” has emerged strongly. Barcelona，which has a long history of urban development，once again provided the world with a new urban development model. This paper systematically sorts out the “Urban Mobility Plan of Barcelona 2013-2018”，trying to explore the inherent nature of superblock planning，and then proposes suggestions for China’s urban construction.
