When designing the membrane structure landscape in the city square, the following problems need to be considered:

1. The design of landscape in the square should give the square rich cultural connotation.

2. The square landscape should be coordinated with the surrounding environment to form the activity center of the city. When designing, we should consider the historical, cultural characteristics and value of the city where the square is located. Pay attention to the landscape connotation of design, deeply comprehend and understand the specific differences and needs of different cultural environments, and design the cultural square landscape under the cultural environment and the background of the times.

3. The type and structure of landscape space are in harmony with the surrounding environment in spatial proportion. The structure of the membrane structure landscape in the square is generally an open structure. The important factor of the square environment is the surrounding buildings. Combined with the planning nature of the square, the historical buildings are protected and the surrounding buildings are well integrated into the square environment by using reasonable and appropriate treatment methods. The type and level of square space can be regarded as the level and type of the space structure of the square environment system. The improvement of the system structure will help to solve the diversified needs of square use. The structure level of the rich space is divided into the main and subordinate, public and relative privacy areas in the whole square by means of the scale enclosing degree and ground texture.

4. The landscape is in harmony with the building environment and traffic organization around the square. Surrounding the square landscape is the gathering place of pedestrian and vehicle flow, traffic organization, which is an important factor to ensure its environmental quality from external interference. In terms of the traffic organization in the inner part of the square, people's visit, browsing, communication, leisure and entertainment should be considered. In combination with the nature of the square, the pedestrian and vehicle flow should be well organized to form a good internal traffic organization so that people can enjoy the place and communication opportunities of the square landscape without interference.

5. Signs and identifiability. The sign itself is to increase the recognizability of the square. Therefore, the recognizability requires the strange characteristics of things, and the membrane structure landscape will strengthen the rationality and value of its existence for the city square.
