The theme sculpture of a city square is usually the focus of a city center or a specific area, which enhances the cultural taste of the city square, makes it the most attractive and intriguing part of the urban landscape, and promotes the progress of urban civilization. The expression content and cultural orientation of the theme sculpture in the city square should not only be closely combined with the historical and cultural conditions, ethnic and religious beliefs, artistic atmosphere, natural environment and unified image construction plan of the city, but also be combined with the specific conditions of a specific region and a specific space, so as to make the theme to be expressed clear, concentrated and appropriate according to the principle of individuality, and highlight the personalized brilliance and aesthetic value of art. Adapting a specific work into a specific environment makes this work only suitable for this environment, but not widely suitable for other environments, in order to break through the limitations of real space and expand the scope of spiritual space. This is a problem that should be considered in the creation of theme sculptures in city squares. At present, China's urban construction is entering an unprecedented period of prosperity, which is a good opportunity for the development of sculpture art.

However, we are also soberly aware that there are quite a few sculptures in city squares, which are similar in form, superficial in content, vague in theme and pale in expression. They are so-called "propositional" works, which are denounced as "vegetable sculptures" by people in the industry. This situation is caused by the lack of cultural self-confidence and artistic expression of sculpture creators, and I am afraid it is also related to the owner's disrespect for artistic laws and excessive intervention in creative design. In fact, only when the owners and designers cooperate with each other and put themselves into the creative process can they create high-quality products, and the sculpture of the city square can truly have the orientation and cohesion of a specific space, become the source of square culture and become the spatial focus in the public eye. In the creative practice of urban sculpture, many cities attach importance to the theme refinement of square sculpture, and have launched artistic masterpieces that can be passed down for a long time and have far-reaching influence, which not only enhances the image of the city, but also enhances the artistic taste of urban sculpture. From the traditional spirit and historical and cultural accumulation, find the performance theme suitable for the modern environment. In many cities of our country, there are many contents that can be excavated and summarized, such as a long history and civilization, profound cultural accumulation or glorious revolutionary tradition. Choose an accurate starting point for artistic creation, thus highlighting the historical sense of the square.

Qingdao is a city with glorious revolutionary tradition in the modern history of China. The May 4th Square in this city is close to the city and faces the sea. The 30-meter-high theme sculpture "Wind in May" is a sculpture created in the traditional spirit. She is thriving and full of strong visual impact. The square is dazzling because of it, and the famous sculptures in the city complement each other with the environment because of it. Draw creative inspiration from human scientific and technological civilization and extract a brand-new theme. In the glorious history of human civilization, the Chinese nation has created many achievements in scientific and technological civilization. Some city square sculptures have launched a large number of works of art with strong modernity around this theme. The large-scale landscape sculpture "Dong Fangzhiguang", which stands on the century avenue in Pudong, Shanghai, takes the ancient China as the theme, indicates the time with the rays of the sun, and expresses the scientific and technological civilization in the new century with modern architectural techniques. This sculpture, which is made of 1000 stainless steel pipes, is about 20 meters high, 22 meters in diameter and 40 meters in length, making it the largest metal sculpture in China at present. This sculpture art practice based on China traditional civilization has positive exploration significance. Excavate materials from regional culture and show personalized charm. China has a vast territory and abundant resources, and its regional civilization and geo-culture have their own characteristics.

As the saying goes, one side's soil and water support one side's people, as well as one side's regional culture and aesthetic characteristics, such as "Tiema autumn wind north, apricot blossom south and spring rain south." The south is soft, the north is rugged and handsome, the west is bold and open-minded, and the east is bright and exquisite ... In Laiyang, Shandong Province, a large sculpture stands on the square in front of the municipal government, with the theme of local five rivers and five tall dragons holding a shining pearl, surrounded by raging flames, making the square a new local cultural landscape with a distinct theme. Draw creative nutrition from folk culture, bring forth the old and bring forth the new, make the past serve the present. Folk culture is vast, and the subjects available for sculpture are very rich. Square sculptures with the theme of positive and healthy contents in folk culture, such as the "four spirits" (forest, phoenix, turtle and dragon) sculptures in the zodiac and sculptures created according to myths and legends, all make the square culture more readable and friendly. These square sculptors, full of positive and romantic spirit, feel the aesthetic pleasure imperceptibly through time-space communication and situational dialogue with them. Excavate creative materials from the spirit of the times and modern life to enhance the modernity of works. Articles are composed of songs and poems from time to time.
