Abstract: Due to the rise of urban development in the Song Dynasty, the number of urban CI increased sharply. The urban CI covered a lot of aspectsof urban life and had a wide range of contents, which were unprecedented in the previous generation. They enjoyed profound representativeness in the construction of literary geographical space.From the perspective of the outer space, urban CI in Song Dynasty is based on the real scenes of the real cities, takes the urban material space as the describing objects, truly restores the literary activities and scenes of the Song Dynasty, and constructs a three-dimensional and regional literary geographical space.From the perspective of the inner space, through the spatial experience and memory of the cities, the poetsof Song Dynasty take the urban geographical space as the carrier and symbol of the poets'emotions, and construct a literary geographical space containing implicitly the universalfeelings of the man of letters in the Song Dynasty.From the perspective of space-time structure, the urban Ci of the Song Dynasty adopts the combination of space-time consistency, space-time dislocation and multiple space-time convolution and interleaving to cross integrate the urban geographical space from different angles and levels, and finally achieve the multi-element construction of literary geographical space from outside to inside and from point to surface.

Key words: literature of Song Dynasty, geographical space, multivariateconstruction, urban CI
