First of all, we need to know what public space is. Simply put, public space is collective space. Small, a home, living room, kitchen, bathroom ... is a public space. Broadly speaking, a society, roads, squares, museums and so on are all public spaces.

Art design is not difficult to understand, is it? I study art ~

Secondly, public art design is aimed at the public, combining your own ideas and creativity in public places in real life, so that the public can recognize the art that you can bring beauty to people.

Thirdly, industrial design, information design, environmental art design and jewelry design are all included in public art design. The design of public space is not only the purpose and result, nor is it a sign that the design caters to a few people, but the process that the public participates in and constantly shows their life changes.

As can be seen from the above knowledge points, since public art is inextricably linked with industrial design, information design, environmental art design and jewelry design. However, these arts themselves do not exist independently in society, and in reality, a market is needed as a carrier to carry the artistic style. With the improvement of people's aesthetic concept, the requirements for beautification of public places are getting higher and higher. For example, people nowadays demand perfection in the one-stop service from material selection to completion.

You can continue to think about this clue from this angle. Such a big topic cannot be finished in a few words. Magnification can be the title of a paper.

I hope my ideas can help you.
