Discussion on the function of 1. 1 square

Xuzhou administrative center square is located in the starting area of Xuzhou New Town. As the front square of Xuzhou new administrative center, it has the fuzziness of square, that is, the imaginability of urban node space, the activity of urban public space, the functionality of assembly and leisure places, and the * * * of history and times.

The main building of Xuzhou administrative center square includes citizen center, party-mass office area, municipal party committee, municipal people's congress office area, municipal government, CPPCC office area, comprehensive government office area, and planned exhibition halls and art galleries on both sides of the plot. It is an administrative and cultural comprehensive central square, so the functions of this square cover a wider range [1]:

These functions are embodied in many practical problems in the design of the square, which makes the square "accept the space of multi-level urban life" and achieve comprehensive results.

1.2 Creation of Place Spirit

Square is a public place where people communicate with each other. A complete place consists of the physical characteristics of space, people's activities and historical and cultural significance. Therefore, we should consider the nature and culture of the region and the present situation of the place when designing, so that landscape design can become a process of interpreting the spirit of the region and the place [2].

The basic content of 1.3 square design

Image, function and environment are the basic contents of modern square planning and design. The image corresponds to the landscape, and the square shapes the image of the city; Functions are used correspondingly, and the square needs to meet different use requirements under different situations; The environment corresponds to ecology and greening.

In the process of landscape design of Xuzhou administrative center square, we always focus on the basic content of the square, meet the requirements of citizens' activities, and make it a new century square that embodies the image of Xuzhou and ecologically beautifies the environment.

2 overall design concept

2. 1 design principle

Through the interpretation of the square foundation site, landscape design should follow the following principles:

(1) Form a square style and style with unique local characteristics and cultural spirit;

(2) to form city signs and symbols with unity of integrity and individuality;

(3) Infiltrate new scientific and technological means with the natural environment to form an intimate and comfortable space atmosphere.

2.2 Themes and ideas

(1) Theme-Seal Xuzhou

"Impression Xuzhou" means "Impression Xuzhou" and "Memory Xuzhou".

Impression of Xuzhou: For passers-by (tourists) in Xuzhou. The landscape image of the square gave them the impression of Xuzhou, and the landscape design also reflected the symbolic special position of the square.

Memory of Xuzhou: For Xuzhou citizens. The square is the square in front of the municipal center and the civic center, and it is the living room of the city. Therefore, the landscape design of the square will arouse the sense of identity and belonging of Xuzhou citizens.

Impression comes from memory, and memory sublimates impression. "Sealing Xuzhou" is the theme of this landscape design. By shaping and excavating the impression and memory of Xuzhou, the taste of the square will be improved.

(2) idea

① Reasonable division of functional areas, in-depth analysis of local context, drawing lessons from advanced landscape design concepts, fully embodying the regional, contemporary, advanced and forward-looking landscape design.

Advocate the "people-oriented" design concept, enlarge the position of the main body of the square-people, improve the walking system, realize the accessibility, crossing, comfort and sightseeing of people by using the three-dimensional walking system, and build a complete, orderly and reasonably connected whole by using steps, stairs and elevators.

(3) Emphasize the mutual promotion between human beings and the ecological environment, build a spatial landscape system combining points, lines and areas, highlight the prosperous atmosphere, rich cultural atmosphere and historical context of the square area, and create a comfortable, beautiful, clean and vivid urban landscape.

④ The detailed design embodies humanization. In the design of the square, the convenience of all kinds of people (young people, children, the elderly and the disabled) should be considered.

3 landscape design

3. 1 landscape layout

The whole administrative center and civic center square contain four plots, thus forming the overall landscape layout mode of "vestibule-square-main building-back garden".

Courtyard: As the elevation of the site suddenly drops by 6m, a group of symmetrical semi-underground buildings are designed on the south side of the central square, and the elevation of the top of the building is the same as that of the square in front of the administrative center. This gap has also created an inner court, making the scale of the square more pleasant. At the same time, the roof of the building is used to decorate the small space for leisure, echoing the sinking inner courtyard, making the square full of green full of layers.

Square: an open gathering and greening square surrounded by curved roads to meet the material function as the administrative center square. Fountains, flower beds and flag stands are set in the center of the circle, and sparse forests and radially trimmed grass enhance the cohesion of the square. The design of the square not only meets the functional requirements of the assembly, but also takes into account people's feelings in the square. Planting large shade trees to shade the sun enriches the green landscape effect of the square.

Main building: separated from the front square by a "moat", forming a landscape environment different from the square. Special emphasis is placed on the use requirements of the office environment, and plants are the main landscaping to create a quiet and simple landscape.

Back garden: the building opposite the road to the north of the main building, with symmetrical parking lots and sports venues. The middle is dominated by cultural landscape, and some small leisure spaces are arranged along the arc moat on both sides. At the same time, greening plants tend to be natural, just like the back garden of the square, which is more private and comfortable.

3.2 Landscape nodes

Landscape nodes run through the whole square, especially in the center of the square, leading the whole landscape space and sequence with the landscape nodes of "ecology" and "humanity".

Ecological view of "returning to the earth"

The development of mankind and the progress of civilization depend on the gift of nature. The earth has nurtured human beings and carried everything, but with the pace of modern civilization, people have forgotten the goodness of the earth more and more, and the spread of cities has covered the vibrant land. Finally, people woke up from blind development, and the reflection on urban heat island and environmental damage became social knowledge, and the ecological concept returned to its proper theme. Being in a city and yearning for nature and ecology has become a social collective ideal. Therefore, designing roof gardens on the semi-underground buildings on both sides of the sinking square, using the change of height difference instead of simple filling, can obtain a unified facade, which not only enriches the spatial level, but also saves earthwork. It is not trying to change nature, but trying to echo ecology by adapting to nature. The choice of local plant varieties has created a natural and rich plant community, and also formed a pleasant scale, suitable micro-topography and microclimate, which is impressive and achieved the effect of "marking" the site, and then became the symbol of the whole square. (Figure 2)

Humanistic idea of "tracing back to life"

The southernmost part of the administrative center square is sunken plaza, with a height difference of 6m from the main building floor. This sinking square is actually built on the existing floor, which is naturally formed by using the height difference between the existing floor and the designed floor. Because of its special facade, the sunken square is surrounded by surrounding structures, forming a visual center and becoming a place to gather popularity. In line with the specific connotation of this place, a group of theme sculpture fountains named "Life" are arranged in the center, and the dry land fountains constitute the water cultural center, reflecting the significance of water to human beings in the form of ground sculptures. Eight sculpture columns are arranged on the north and south sides to record the great achievements of local great men in past dynasties, reflecting the elegance of "the hometown of a generation of emperors", and landscape lamp columns are arranged on the east and west sides to echo it. With the concept of "tracing back to life", people can awaken their memories of history and predecessors, cherish life more and have a sense of struggle for limited life.

The two concepts of "returning to the earth" and "tracing back to life" echoed up and down, the landscape connotation of the square was sublimated, and the unique "imprint" was deeply branded on the "living room" of Xuzhou.
