We researched the design of city square from a new angle of time and space. In order to make four dimensional squares, we have to use all the methods comprehensively, such as composition, decomposition and change, finally, we can make the space more perfect. At the same time, we have to pay attention to the formation of time, emphasize the factor of time, and make design from these perspective: history and culture, spaces series, and plant arrengement etc. But in square design, "human" is always the main body. Therefore, our formation of space and time, have to meet human's behavior requirement.In the end, through investigation and study, we can conclude: square design, must attach importance to four dimensional time and space's formation . time and space's formation of city square must satisfy requirement of human. |
