Three-dimensional development of the future city
We live on a fixed-size planet and live in a society with a growing population. On the surface, will our per capita possession area become smaller and smaller? Will the land be used up one day? In-depth view, China’s urbanization is developing very fast now, but China’s current urbanization error model has led to several major Dysentery - high pollution, high energy consumption, traffic chaos, congestion, dysfunction and high cost of living, high prices of land prices, people's happiness is seriously frustrated. This requires us to re-examine our living environment and seek new ways. Today's building technology is getting higher and higher, and high-rise buildings have risen to form a piece of cement forest, which has developed the human city from the plane to the space. This is our future trend, the three-dimensional city.
As for the three-dimensional city, we have heard a lot, from many media reports to the description of the novel "Love in the City", this is a big dream to solve China's economic problems - ultra-high density giant architecture. The most popular practice of urbanization in China today is the “spreading the pie†model, the so-called “big city†framework, as if the city was naturally urbanized. This has created a strange phenomenon in the boundless city. "Western-salty integration" and "Zheng Zheng integration" suddenly found that many provincial capitals and surrounding areas are implementing integration, and perhaps one day, they will go to Washington and New York.
But this growing city has brought many new problems that are difficult to overcome. The land price in the central city is getting more and more expensive. It is a must-have for everyone to get away from the office. The work is getting harder and harder: there are cars on the ground, and no cars are blocked at the bottom. Beijing people have dubbed Beijing as the first. . In addition to congestion, the long time spent on the way to and from work is also an important factor that greatly reduces the happiness of everyone. I have been working for two hours, and I have been working for two hours. The anxiety caused by congestion is also a kind of wrath for people's spirit. When I get home, I am exhausted. Naturally, I don't have time to exercise, relax, enjoy life, and then come along. It is a variety of urban diseases.
Moreover, the pollution is serious. Air pollution and urban pressure have brought many diseases and cancers are also growing.
The city is accompanied by the problem of unreasonable functional planning and inconvenient urban life. Almost every provincial capital city now has several CBDs, but the per capita GDP does not exceed 10,000 US dollars. In fact, there is only one CBD in Tokyo and New York, but the per capita CDP is $50,000 in Tokyo and $60,000 in New York. The agglomeration of the CBD has led to a rise in housing prices, and many incumbents have had to separate their place of residence from the place of employment. Maybe go to work in one place, entertain a place, see a place in a hospital, sleep in a place, fall in love with a place, spend every day in the running. Why is it that this kind of function is not concentrated? Without the initial planning of the system, blindly pulling the big city framework, while expanding and constructing the urban construction in a patchwork manner, will inevitably lead to urban dysfunction, and life, employment,
The separation of entertainment, medical care and education has made this disorder even more intense.
The great difficulty brought by the final urbanization is that the living expenses are getting higher and higher, the heart is getting more and more depressed, the happiness is getting lower and lower, the house is more, the wallet is smashed; the house is big, the happiness is gone: so now everyone starts to discuss Happiness, start to compare where people are happier.
Three-dimensional city of 10,000 yuan per square meter
Chengdu has always been a city with a high sense of well-being. People there will manage their own desires. They like to drink a bit of wine, play a small mahjong, talk about small love, and be very happy and satisfied. Many people in Chengdu call love dating a small love. Chengdu is so free and easy in the country, and Chengdu is a city that can accept large-scale innovations. The three-dimensional city is also suitable as a pilot implementation in Chengdu.
Let's talk about the major diseases that we have to solve. We find that the "spreading the pie" model has gone wrong. Then, instead of doing the same thing, we will start the "small cake" mode. Zooming out the cake to Gaoli, this city has several new features:
First, it has changed from a plane to a three-dimensional one;
Second, the density is increased and the floor area ratio is increased;
Third, the space layout inside is several times more complicated than the original;
Fourth, management is more intensive.
Just like the high-integrated circuit we use now, anything in a fingernail-sized object can fit down, become smaller, taller, denser, but better.
In this way, when office buildings, businesses, schools, shopping centers, medical institutions, and accommodations are brought together, the area of ​​green space around this high-density building has also increased. What needs to be studied to build a three-dimensional city now is how many houses should be built on a square kilometer, how many people are installed, how many people are employed, how to organize transportation to save energy, environmental protection and sustainable development also make people live comfortably.
After a lot of comparison studies, the better scale is that 600 square meters of above-ground buildings and 30 square meters of underground buildings can be built in one square kilometer. This number is half that of Chicago, and it is obviously much better. 6 million square meters for IO million people, of which 340 square meters of housing for 100,000 people to sleep at night, an average of 34 square meters, more than 28 square meters per capita in our current city, which is more than Beijing's Wangjing, Guomao Even Manhattan in the United States is much more comfortable. These previous studies were used to promote the theory of “eat soft rice, cuckold hats, and earn hard money.†This kind of research is “eat soft riceâ€.
Today, there is an opportunity in front of us like the era of Manhattan skyscrapers. We must use a new technology and a new invention to sort out some skyscrapers and rationalize them so that they are functionally connected and low-carbon. Three-dimensional cities can completely solve the problem of reducing carbon emissions. Now the design of the overall energy system of the three-dimensional city is the supply of water, electricity and gas. This distributed energy source has a central factory, which is then used to reach the ports through the transmission system, to solve the problem locally, to cycle in place, and to reduce energy consumption by 35% compared with the traditional city. In addition, the green plot ratio is twice as high as that of the traditional city, 35% of the public land, and the vertical greening and roof of the building.
Greening, plant factories, etc.
People's consumption in a three-dimensional city will be greatly reduced, no need to drive to work, and house prices have also come down. The renovated house is priced at less than 10,000 yuan per square meter. We will do public rental housing, low-rent housing, affordable housing in the three-dimensional city, and will also do commercial housing and a small number of expensive rooms, but the overall average price will not be higher than this number. In such a convenient place than a traditional city, the cost will be much less.
Its management system has also greatly improved. Previously, the divisional management of streets, neighborhoods, governments, and development zones will use technology to manage different functions into one overall system. Let people live a life of “soft food, green hat, hard money†in places that can afford and live habitually.
