In this study, the connotation of indigenous landscape is analyzed from the perspectives of local culture, integration of Chinese and western cultures, folk cultures and modern marketing, the causes of duplicated urban square landscapes are thoroughly elaborated. In view of the deficiencies of modern urban square landscapes, it is proposed that local plants, local ornamental materials and patterns should be fully applied in square designs, and the expression of detail landscapes should be attached sufficient importance, to completely demonstrate regional features of landscapes and better apply indigenous landscapes into the design of modern urban squares.
