Introduction to the contiguous areas of large cities, and the introduction of contiguous districts o

The contiguous areas of large cities are generally large urban agglomeration areas with a belt-like distribution. Centered on a number of large cities with a population of hundreds of thousands to more than one million, large and small towns are distributed continuously, forming the most urbanized areas. It is home to a significant part of the country's population and economic activity.

Many of them are of global significance, and often have international seaports. In addition to residential areas, industrial areas and commercial service areas, there are also agricultural functional areas in the contiguous areas of large cities. Although the economic benefits of the contiguous areas of large cities are higher than those of radial large urban areas, the ecological balance between human activities and the natural environment has been destroyed due to the excessive concentration of population and economic sales, so it is necessary to prevent its continued expansion when planning orange teasing.

The urban contiguous area is a giant urban-rural integration area formed by the continuous distribution of several metropolitan areas along the comprehensive transportation corridor, and is the core area of the country's economic ascension. The urban contiguous area belongs to the functional area of the city, which is composed of the central city above a certain scale and the peripheral areas that maintain close socio-economic ties with it and have developed hail and non-agricultural activities.

Geographers certainly believe that there is value in the work of analysing and describing a particular geographical area with some consistency and originality, and thus distinguishing it from its neighbors. Although such an area may be unique in the world, it is often considered worthwhile to investigate its characteristics, problems, and structure.

With the gradual accumulation of data describing this unique case, people in the geographical field have been working hard to explore universal laws and carry out case analysis. The results of this study would be of direct value, as they would be applicable to more than one area or region to some extent. For a long period of time, the contiguous areas of large cities have actually become the vanguard of urban living organisms.

Features such as skyscrapers, elevators, train networks in cities and suburbs, traffic lights, and one-way streets were first introduced here before being applied and popularized around the world. The large urban contiguous area was developed by a network of numerous maritime towns that grew rapidly in the early days. These towns are spread along the coast from Boston to New York, and then along the coastline from New York to Washington.

The large scale of major cities in large urban contiguities, especially New York and Philadelphia, led to a rapid expansion of suburbs between large cities. James Madison defines New Jersey as a "barrel tapped at both ends." It was already clear to this wise observer by the late 18th century that the primary role of New Jersey was to connect the two districts of New York and Philadelphia.

The polynuclear structure of large urban contiguous districts is beginning to repeat itself elsewhere. For example, a huge urban area and suburbs are rapidly expanding around Los Angeles, actually reaching the inland city of San Bernardino and potentially connecting with San Diego along the coast. On the shores of Lake Michigan near Chicago, another impressive megacity contiguity is taking shape.

Within Ohio, the expanding metro area between Cleveland and Pittsburgh is close to contiguous; And the St. Lawrence Sea Passage (the stLawrence Seaway, once it opens, is likely to accelerate to the southern reaches of Lakes Erie and Ontario. Across the United States, more and more metropolitan areas are expanding their tentacles into suburban areas; At the same time, other smaller megalopolis-like clusters will be formed.

This process will bring about considerable changes in the way of life in the United States. This trend will be easier to understand once the case of the largest and most developed urban contiguous development, the situation of the large urban contiguous areas described in this article, is thoroughly analyzed.

Since 1982, on the basis of collecting data from more than 100 countries in the world, Chinese urban geographer Yi Yixing has carried out theoretical and index system research on the relationship between economic development and urbanization, and put forward the idea of China's regional urban system - urban contiguous area. The "urban contiguous area" is a giant urban-rural integration area formed by the continuous distribution of several metropolitan areas along the comprehensive transportation corridor, and is the core economic area of the country. "Urban contiguous area" belongs to the functional area of the city, which is composed of the central city above a certain scale and the peripheral areas with which it maintains close socio-economic ties and has developed non-agricultural activities.

At the same time, the discriminant index for the formation of "urban contiguous area" was also formulated. Zhou Yixing was the first in China to propose the practice of organizing "urban contiguous areas" to solve the problem of inter-regional coordination, and this achievement was widely used and became one of the theoretical bases for his lecture to the Politburo in 2006.

In addition to the urban contiguity and daily life area, there is another important area in the city, and that is the administrative district.

An administrative district is an administrative division that is usually managed by a ** agency. In China, administrative divisions are based on provinces, and are divided into prefecture-level cities, county-level cities, counties, townships, and villages. Administrative divisions play an important role in the planning, management and service of a city.

The division of administrative divisions is based on a variety of factors such as geographical location, population, and economic development, so the administrative divisions of different cities may be different. Administrative divisions are also an important consideration in urban planning.

In daily life, the administrative division of Chuncong will also affect people's lives. For example, the allocation of public resources such as education, medical care, and transportation may be different in different administrative divisions, and residents need to make corresponding choices and adjustments according to their administrative divisions.

For urban planners and managers, understanding the division and characteristics of administrative divisions, and carrying out scientific and reasonable planning and management, can better meet the needs of residents and improve the overall development level of the city.

Extended description: In addition to administrative divisions, there are many other regional divisions in the city, such as commercial areas, industrial areas, cultural areas, etc. These different zoning divisions have different characteristics and functions, and have an important impact on the development of the city and the lives of residents.

Therefore, in urban planning and management, it is necessary to divide and plan these areas scientifically and reasonably to achieve sustainable development of cities.
