After the reform and opening up, China's urbanization process is advancing rapidly, and the urbanization rate is constantly increasing. Too many resources and population are concentrated in the city, so that it exceeds the limit of its carrying capacity. In 2010, China entered the post-industrial era, and as a traditional production-oriented city, Harbin urgently needs to transform into a modern comprehensive city that is "livable, suitable for business, and suitable for travel" Today's urban boundaries continue to expand and spread, and this is not only a squandering of land resources, but also led to the excessive dispersion of urban functions, but also further caused a sharp rise in traffic. When more and more fields are smeared with traffic hazards and car noise and exhaust by criss-crossing roads; when large tracts of soft and tender grass are overturned and rebuilt into icy asphalt roads; when the distance of the academy leads to alienation of interpersonal relationships...... We can't help but ask, what are the children who should be playing and running in the arms of nature? When inspecting Beijing, General Secretary Xi pointed out that in order to curb the development of "spreading the pie", it is necessary to achieve agglomeration, integration and low carbonization. The idea of this scheme is to closely integrate the various functional parts of the city through the establishment of an ultra-high-density urban complex model. With the new model of vertical development, it is returned to nature and even to children, a green and natural paradise without the threat of car dealerships. The underground part of the single building is equipped with factories, and the first floor is connected to the outside. It is envisaged to provide food for the residents of the mound for the function of the plantation. On it are the metabolic school and dormitory, followed by the commercial and medical comprehensive service area, and the residential area is located at the top. By Midjourney the aid of this AI tool, the iteration of the scheme version is carried out, and the architectural effect diagram and the site effect diagram are designed. Finally, the expected image of the site and section is achieved by Rhino modeling.
