3 Landscape Design
3.1 Landscape Layout
The whole administrative center, civic center plaza includes four plots, thus, forming a "forecourt - square - the main Building - back garden" of the overall landscape layout model.
Vestibule: due to the site elevation suddenly lowered by 6m, through the use of this difference in elevation, but also to reduce the amount of earthmoving, in the center of the square on the south side of the design of a group of symmetrical semi-underground buildings, the top of the building elevation and the administrative center of the square in front of the same. This difference in elevation also creates an inner courtyard, making the plaza more pleasant in scale. At the same time, the roof of the building is used to arrange greening and leisure space, echoing up and down with the sunken inner court, so that the greenness of the square continues and the level is rich.
Square: enclosed by the arc of the road, forming an open assembly and green square to meet the material function as the administrative center square. The center of the circle is set with fountains, flower beds and flagstaffs, and the periphery of the plaza is enhanced with sparse forests and grasses trimmed with radial texture to enhance the cohesion of the plaza. In addition to meeting the functional requirements of the assembly, the design of the square takes into account the feelings of people in the square, planting large shade trees to shade and enrich the green landscape effect of the square.
The main building: separated from the square by a "moat", forming a landscape environment different from that of the square. Special emphasis is placed on the use of the office environment, with plants as the main landscaping to build a quiet and simple landscape.
The back garden: north of the main building, across the road from the building, using a symmetrical layout, set up parking lots, sports venues, in the middle of the cultural landscape construction, both sides of the moat along the curve of the arrangement of a number of small leisure space, at the same time, green planting tends to be natural, just like the square of the back garden, more private, but also more comfortable.

Landscape nodes throughout the square, especially in the center of the square to "ecological" and "humanistic" two concepts of landscape nodes lead the entire landscape space and sequence.
The ecological concept of "returning to the earth"
Human development and civilization progress depends on the gifts of nature. The earth nourishes mankind and carries everything, but with the footsteps of modern civilization, people are forgetting more and more about the kindness of the earth, and the spread of the city has covered the vibrant land. Finally, people are awakening from the blind development, the urban heat island, environmental destruction of the rethinking has become a social **** knowledge, ecological concepts once again returned to its rightful place in the main. Being in the city and yearning for nature and ecology has become the collective ideal of the society. Therefore, the design of roof gardens on the semi-underground buildings on both sides of the sunken plaza utilizes elevation changes rather than simply filling in to obtain a uniform elevation surface, which enriches the spatial hierarchy and saves earthwork, not trying to change the nature, but attempting to echo the ecology by adapting to the nature. The selection of local plant species creates a natural and rich plant community, as well as a pleasant scale, suitable microtopography and microclimate, which is impressive and achieves the effect of "imprint" of the site, and then becomes the symbol of the overall square.

Meaning. The north and south sides of the arrangement of eight records of the great achievements of local great men of all times sculpture columns, reflecting the "generation of emperors and kings of the township" style, the east and west sides of the layout of the landscape light columns and echoed. To "trace life" as the concept, to awaken people for history, the memory of the past, for the life of the double cherish and for the limited life glow of the consciousness of hard work.
