Urban structure and characteristics of China.

The ancient urban structure of China is a grid structure centered on imperial power, with convenient transportation, symmetrical cities or freely arranged structures based on mountains and rivers. Now many cities in China have developed into the following structures:

Concentric circle type: central city, urban periphery and outer city, which explains the increase and division of urban land. The farther away from the center, the higher the rent.

Fan shape: developed from concentric circles, focusing on the radiation traffic impact between the communication center and the outer city. This kind of structure is dynamic, which makes the urban regional structure easy to adjust and change, and urban activities can expand along the traffic lines.

Multi-karyotype: that is, a city forms central business district, residential district and industrial district around several cores. Such a city has many growing points, and the area with the best traffic location can form the central business district.
