What are the disadvantages of traditional closed cities?

What are the shortcomings of the development of traditional closed cities?

I benefits of urbanization:

Reasonable urbanization can improve the environment, for example, by leveling the land, building water conservancy facilities, greening the environment and other measures, so that the environment can be transformed into a direction conducive to improving people's living standards and promoting social development, and the pressure of human activities on the environment can be reduced.

As the economic center of regional development, it can promote regional economic development, and the improvement of regional economic level can promote the development of cities; Promote the change of production mode, settlement mode, lifestyle and values.

1, population transition

Cities can create more employment opportunities and absorb a large number of rural surplus population. The labor force gradually shifts from the primary industry to the secondary industry, the tertiary industry and the fourth industry.

2. Industrial adjustment

The process of urbanization can effectively promote the development of rural areas and help improve the regional industrial structure.

3. Industrial development

Urbanization helps to improve the efficiency of industrial production, and industrialization gives sustained impetus to urbanization.

4. Scientific and technological progress

With the progress of science and technology and the advancement of informatization, modern big cities have become the main scientific and technological innovation bases and information exchange centers. So as to improve the overall development level of the region.

5. Cultural exchange

The extensive diffusion and infiltration of urban culture into rural areas has affected the production and lifestyle of rural areas (self-sufficient natural economy) and improved the openness of rural areas. Conducive to the communication between urban and rural areas, narrowing the gap between urban and rural development.

6, the driving force of development

There are only two driving forces to promote the development of urbanization, one is thrust and the other is tension. Push is the factor that leads people to leave the countryside, while pull is the factor that attracts people to the city.

Motivation, such as the intensification of the contradiction between man and land, frequent natural disasters, low income, poor living standards, and shortage of social service resources. Larry has many employment opportunities, rich social service resources, convenient transportation and complete cultural facilities. ?

Second, the disadvantages of urbanization:

1, biosphere

Reduce biodiversity

2. Lithosphere

As a result, the cultivated land area is reduced, soil pollution and land subsidence are caused.

3. Atmosphere

Air pollution. Intensify the heat island effect and greenhouse effect

4, hydrosphere

Infiltration decreases and surface runoff increases; Water quality deterioration; Shortage of water resources; acid rain

Step 5 transport

be stuck in a traffic jam

6. House

Housing tension

Step 7 hire

Employment difficulties

8. Social order

Social disorder (high crime rate)

9. Moral atmosphere

The moral atmosphere is declining.

10, social security

The pressure of social security is increasing rapidly, and the social security gap is difficult to fill.

1 1, economic impact

As the land price rises, so does the cost.

12, food problem

A large number of farmers have left the original cultivated land, and the problem of abandoned land is becoming more and more serious. China's grain import rate has gradually increased, which makes the food security problem of China, a populous country, hidden, which is not conducive to China's national development and political stability.

13, big city disease

The diseases in big cities in China are quite serious now. Problems such as traffic congestion, shortage of resources, and decline in the quality of life of urban residents are plaguing the progress of the city. The pace of construction and transformation of big cities in China has been accelerated, and urban circles have begun to appear in some parts of China, and many mega-cities have also begun to build "satellite cities", hoping to solve many big city diseases.

14, transformation of urban functions

The urbanization process in developed countries can be roughly divided into two stages. The first stage is characterized by "centralization" and the second stage by "decentralization". As a result, "metropolitan circle" or "urban agglomeration" and "urban belt" centered on big cities have developed rapidly.

In some developed areas of China, such as Beijing, Shanghai and Guangzhou, there has been a trend of the affluent class migrating from cities to suburbs, that is to say, it has entered the second stage of urbanization: "suburbanization stage". The development of "city circle" and "satellite city" needs to pay attention to the transformation and coordinated development of urban functions and surrounding suburban functions.

The process of urbanization is the process of continuous modernization, and central cities should constantly improve the scale, layout and function of "urban belt" and "regional economy". The continuous evolution of urban functions is the premise of the good development of central cities, and it is also the basis for solving the diseases in big cities and promoting the stable and healthy development of surrounding areas.

Extended data:

Various aspects of urbanization:

1, travel

"Urbanization" is "people's urbanization" and people-oriented urbanization. It can be said that "urbanization" is not the same as "industrialization", and the "non-industrialization" urbanization mode oriented by tourism is a very important and worth popularizing.

First of all, we should firmly grasp the general direction of ecological civilization construction, take "green development, circular development and low-carbon development" as the leading principle to realize urbanization, guide urbanization construction to take the "beautiful" road, and make "beautiful China" a livable, business-friendly and business-friendly China.

Secondly, we should persist in protecting and inheriting local culture, maintain and strengthen local individuality, take cultural shaping as the driving force of local social and economic development, and simultaneously enhance local soft power and hard power through cultural construction.

Thirdly, it is necessary to plan and organize the industrial format, take the tourism-oriented urbanization development model, advocate the "non-industrialization" new urbanization road, and take tourism, cultural and creative industries, modern service industries and other modern new real economies as the main body.

Build a new industrial pattern characterized by "people flow drives logistics and capital flow", and create better, higher and more quality economic and social development achievements than traditional formats with innovative formats.
