The rapid development of urban sculpture has increasingly become an important part of environmental art and the expression of urban image. Sculpture materials are mostly natural stone, artificial stone, wood, metal, cement and new materials such as plastic, rubber, stainless steel, aluminum alloy, gold copper, glass fiber reinforced plastic, etc. In order to cater to the trend of people's "returning to nature", break through the stereotype of traditional sculpture "steel and cement", enrich the environmental space, better protect and beautify the environment, reflect the meaning of sculpture, and make the urban landscape more attractive and cultural and artistic taste, "green sculpture" came into being at the historic moment, quietly sweeping all countries in the world. It refers to the artistic image with different postures and vivid charm, which is carefully cultivated and pruned by various green plants, especially trees. It combines garden and sculpture art, skillfully integrates the theme of "people, animals and nature" into beautifying the urban environment, and has a wonderful effect of shaping a beautiful image of the city and protecting the urban environment. The green sculptures are generally novel in design and rich in meaning. The overall style is beautiful and grand, full of modern flavor. Green sculptures are not only rich in materials, but also can release oxygen needed by human beings, absorb carbon dioxide, purify air, regulate air humidity, and bring health and artistic enjoyment to the city.

Micro carving is a kind of carving technique that is good at small and fine. Chinese micro sculpture has a long history. Miniature carvings appeared in oracle bone inscriptions as far back as the Shang Dynasty. During the Warring States Period, the seal was as small as millet, but the seal was divided into white and black. Wang Shuyuan's Nuclear Boat Story, which is widely known, is also a classic work of micro sculpture in Chinese history. The art of seal cutting is the basis for the emergence and development of micro carving art. Since the Ming and Qing Dynasties, many literati and scholars have used iron pen to write and paint in the seal, to express their interest and entertain themselves. After Shoushan Stone became the seal material, the micro carving art of Shoushan Stone began to appear. At the beginning of the Qing Dynasty, Yang Xuan and Diaobin both carved small characters in the remote patterns of Shoushan stone carvings. Lin Qingqing, a master of "Ximen Boyi School" carving, often wrote his name and the date of production in the grass and stone crevices of the carved works with extremely fine pens. Later, some people carved ancient poems with extremely fine characters on the four sides of the square pillars of the seal as margin. In the 1960s, with the application of advanced scientific instruments such as magnifiers in the field of micro sculpture, micro sculpture art became a new and unique art. The words carved in the works are smaller and smaller, and the content is more and more. Microcarvings pay special attention to the selection of materials. The texture of the Hainan EPS component stone is required to be absolutely pure, and there should be no sand grid and half silk cracks, because half of the sand dot may be engraved with more than 10 Chinese characters. Secondly, the micro carving knife is also a special thin knife, which should be sharp and sharp. Third, it is necessary to have a particularly proficient knowledge of calligraphy and traditional Chinese painting. When carving, you can carry out "free engraving". Fourth, hold your breath and concentrate on your thoughts on the spot. Fifth, the knife should be handled steadily, accurately and ruthlessly. Only in this way can calligraphy and knife technique be perfectly unified. The art of micro sculpture is "art in micro". The more subtle it is, the more refined its kungfu is, and the higher its value is. Microcarving is also an art that pays great attention to the picture and organization, which is "intended to be refined". The sculptor of micro sculpture must first have a deep knowledge of calligraphy and painting. Although the micro sculpture is too small to be recognized with the naked eye, it is still very exquisite under the magnifying glass, such as large calligraphy works.

The art of carving various patterns and images on stones, usually also refers to sculpture handicrafts carved from stones. Chinese stone carving can be divided into bluestone carving, marble carving, white marble carving, talc carving, black crystal carving, colored stone carving, pebble carving, etc. Hui'an, Fujian, is famous for its bluestone carvings for architectural decoration and stone lions, among which the mouth of the stone lion contains stone beads that roll freely, and is famous in Southeast Asia. The marble carving in Yunnan is made from the marble of Diancang Mountain. Its patterns are like colored mountains and rivers, or dangerous peaks and valleys, or waterfalls follow the clouds. The inlaid furniture is unique. White marble carvings in Quyang, Hebei, Fangshan, Beijing and other places were mainly used for palace architectural decoration in the Ming and Qing dynasties, such as Huabiao, stone lions, railings, etc; Modern times are used for decoration of public and memorial buildings, such as the Great Hall of the People, the Monument to the People's Heroes, Chairman Mao's Memorial Hall, etc. Talc carvings in Haicheng, Liaoning Province and Laizhou, Shandong Province use small and cute animals as traditional varieties. The carvings of black crystal stone in Dongkou, Hunan and Lichuan, Hubei are dark and bright. Caishi carving is mainly produced in Qingtian, Zhejiang, Shoushan, Fuzhou, and Liuyang, Hunan. Pebble carvings are mainly produced in Lanzhou, Shenyang and other places. Stone carving techniques include intaglio (contour carving), shadow carving, relief, round carving (complete three-dimensional carving without any background), and openwork (also known as openwork). Shadow carving is a unique technique of Fujian Hui'an bluestone carving. It uses steel drills of different sizes to chisel on the bluestone, and uses the size, depth and density of the drill points to express the images of landscapes, birds, animals, people, flowers, etc.

Auxiliary tools for wood carving: mainly hammer, wood file, axe and saw. The purpose of the axe is to cut a large amount of wood with the help of paring. Pay attention not to use too much force when cutting. Do not cut straight up and down. The edge of the axe should be kept at about 45 degrees with the vertical wood grain, otherwise the wood will crack. Hainan GRC component wood file is mainly used in the fine blank stage of round carving, which can replace the flat knife to smooth the chisel marks for polishing; It can also take the place of round knife or oblique knife for hollowing. The function of the wood file is also that it can quickly adjust the modeling structure in a large area, and can be used in combination with the carving knife to make the turning and turning of the figure's clothing patterns vivid and smooth, with both virtual and real effects. The shape of hammers for wooden sculptures in Hainan is flat, flat, wide and square. The dimension of hammer face can be controlled at about 7 × 5.5 × 2.5 cm. Too narrow or too thick will affect the accuracy of the hammer's landing point and the uniformity of force. There are two kinds of hammers: wooden hammers and iron hammers. The wooden hammers generally use hardwoods with a large proportion of wood, such as mahogany, boxwood, sandalwood, beech and fruit trees. The specifications can be controlled at 27 cm in length, 55 cm in width and 45 cm in thickness; The grip is round and slightly flat, and the size is suitable for holding in the hand.

The openwork carving technique is an original carving technique in Putian. There are still many "gold inlaid openwork lanterns" and "embossed flower windows" in the Palace Museum in Beijing, which all support the traditional craft charm of Putian wood carving. From the end of the Ming Dynasty to the beginning of the Qing Dynasty to the Republic of China, Putian wood carvings were mostly made of longan wood, which was rich in local production. Taizhou Abstract sculpture Carved into various military generals, women or gods, antiques, supplemented by cost performance Abstract sculpture The painting with old lacquer makes the work more deep in color. Zhu Bangshou, Huang Dangui, Chen Xiange and other famous painters, together with Liu Ronglin, formed a round sculpture character style characterized by Pu style military generals. So far, many figures and architectural decoration wood carvings have been left for future generations in Guandi Temple, Yuanxia Village, Jiangkou Town, Jiufeng Village, Wutang Town and other old folk houses, These masterpieces, which combine round, transparent and relief carvings, are treasures of Putian wood carving art.

Marble, granite, Hui'an stone, Qingtian stone, Shoushan stone, Guicui stone and other materials are generally used for stone carving. Granite and marble are suitable for carving large statues; Qingtian stone and Shoushan stone are rich in color, which are more suitable for small stone carvings. There are many ways to make stone carvings. According to the nature of stone materials and the habits of the carvers, stone carvings can be roughly divided into two types: first, traditional methods. Conception, composition, modeling and stone carving are all done by individuals alone. For large-scale carving of lines, the horizontal and vertical lines shall be drawn on the stone, the grid shall be made to take materials, and the simple measurement and positioning method shall be used for carving. The second is to adopt a new process, that is, first make a clay sculpture, turn it into a plaster statue, then take the plaster statue (model) as the basis, rely on the point shaped instrument, and then carve it into a stone statue.
