A country with a land area of 3,000 square kilometers

Bhutan. With an area of one square kilometre and a population of less than 800,000, Bhutan is such a small country that occupies 3,000 square kilometres of our land.

The People's Republic of China has a land area of about 9.6 million square kilometers, with a coastline of more than 10,000 kilometers on the mainland, more than 10,000 kilometers on islands, and more than 4.7 million square kilometers on the inland and border seas.

Although 9.6 million is an official figure, it is actually only an approximate number. Strictly speaking, it should be 10,000 square kilometers. Compared with the whole country, 10,000 square kilometers of land looks very small. But in fact, these lands are not a small amount.

For example, the United Kingdom, which we are all familiar with, has a combined land area of only 10,000 square kilometers. The 10,000 square kilometres we often overlook are about one-eighth the size of the UK. In addition to this part of the land, with the continuous development of its comprehensive national strength, China has also recovered some land that was seized by foreign invaders.

For example, places such as the Pamir Plateau and the Black Blind Island have returned to the embrace of the motherland one after another after the founding of New China. Over time, China will certainly be able to regain more of its lost territory, and the total area will grow larger and larger.

About 9.6 million square kilometers.

Bigger than Oceania.

The actual land area of China is now 9601158 square kilometers (kilometers).

The official figure is 9.6 million square kilometers.

The land area of each Chinese dynasty is as follows:

1.The territory of the Qin Dynasty is 3.4 million square kilometers.

2.The land area of the Western Han Dynasty is 6.09 million square kilometers.

3.The Eastern Han Dynasty covers an area of 5.8 million square kilometers.

4.During the Three Kingdoms period, the land area was 2.91 million in Wei, 1.06 million in Shu, and 1.45 million in Wu.

5.The land area of the Western Jin Dynasty is 5.43 million square kilometers.

6.The land area of the Sui Dynasty was 4.67 million square kilometers.

7.The Tang Dynasty had a land area of 12.37 million square kilometers.

8.The land area of the Northern Song Dynasty is 2.8 million square kilometers.

9.The land area of the Southern Song Dynasty is about 2 million square kilometers.

10.The land area of the Yuan Dynasty was 13.72 million square kilometers.

11.The Ming Dynasty had a land area of about 9.97 million square kilometers.

12.The Qing Dynasty had a land area of 13.16 million square kilometers.

"3 million square kilometers" is China's recognized maritime land area. During the interview, this reporter learned from authoritative departments that China's ocean area is 10,000 square kilometers, about one-third of the land area. ；There are also some maritime territories that are disputed.

According to the Oriental Outlook Weekly, in the Yellow Sea, 250,000 square kilometers of the 380,000 square kilometers should be placed under China's jurisdiction. However, on the issue of maritime demarcation, the ROK advocates an equidistant line as the boundary, and if it is divided according to this, the DPRK and the ROK can draw an additional 180,000 square kilometers. In other words, China has 180,000 square kilometers of disputed sea areas with the DPRK and the ROK.

In the East China Sea, the Diaoyu Islands, China's inherent territory, were illegally occupied by Japan; The continental shelf of the East China Sea is a natural extension of China's landmass, so 540,000 square kilometers of the 770,000 square kilometers of the sea area should be under China's jurisdiction. According to Japan's unreasonable demands, Japan and China have 160,000 square kilometers of disputed areas.

In the South China Sea, China's maritime rights and interests have been violated even more seriously.

The geography section of the Yearbook of the People's Republic of China reads: "China's land area is 9.6 million square kilometers, and the sea area is 10,000 square kilometers".That's what China.com said:

China is located in the east of Asia, on the west coast of the Pacific Ocean. The land area is about 9.6 million square kilometers, the coastline of the eastern and southern continents is more than 10,000 kilometers, and the water area of the inland sea and the border sea is about 4.7 million square kilometers. "This does not say the area of the sea under China's jurisdiction, only that the water area of China's inland and border seas is more than 4.7 million square kilometers.

The Bohai Sea, the Yellow Sea, the East China Sea, and the South China Sea are marginal seas around China, with an area of 10,000 square kilometers respectively. Combined with the 80,000 square kilometers of the coastal area within 200 nautical miles of eastern Taiwan, the offshore waters around China do have 4.73 million square kilometers.

However, not all of China's coastal waters are under China's jurisdiction. The Yellow Sea should be demarcated with North Korea and South Korea, the East China Sea should be demarcated with Japan, and the South China Sea should be demarcated with more countries. As a result, the area of the ocean under China's jurisdiction is much smaller than 4.73 million square kilometers.

It is estimated that the total area of the ocean under China's jurisdiction is about 3 million square kilometers. But some of them are also disputed with neighboring countries.

The theoretical basis for daily maintenance and repair, so the construction of the highway maintenance and repair data platform must be clear about the maintenance tasks, including all the contents of daily maintenance and maintenance, assign the tasks to the relevant management personnel and technical personnel, and put forward clear provisions on the work content and requirements, and quantify the management of the maintenance and maintenance tasks, so as to realize the integration, standardization and scientificization of the data platform, so that the maintenance and repair work of the highway can be carried out more smoothly. Standardized management of conservation technology.

According to the actual work and technical level of the technical personnel involved in the maintenance and repair work, the construction of the highway maintenance and repair data platform can refer to the ISO document system architecture form, and incorporate the operating procedures and instructions related to the maintenance and repair work on the platform to enrich the document architecture of the data platform. After the establishment of such a document framework, the relevant technical personnel of the maintenance and repair work must fill in the corresponding technical information in accordance with the specifications, so that on the one hand, the phenomenon that the maintenance and repair tasks cannot be implemented due to the inconsistency between the procedures and instructions and the actual maintenance and repair work is effectively avoided; On the other hand, it is conducive to the cultivation of standardized operation habits of maintenance and repair related personnel, and at the same time, it can also define and standardize technical indicators and operation processes, so as to realize the standardized management of maintenance and repair technology. Accumulation and utilization of conservation experience.

The highway maintenance and repair data platform needs to establish a disease database, which includes disease data and disease control countermeasures. The relevant staff are required to classify the diseases found during each inspection into the disease bank, and at the same time, after the disease is treated, the relevant treatment methods should also be included in the treatment countermeasures database in the disease bank. With the passage of time, there will be more and more data in the disease database, in the future work, the maintenance and repair data platform can provide a large number of disease data for the relevant staff and technicians, if the same or similar diseases are found, the relevant staff or technical personnel can find the corresponding treatment methods in the disease countermeasures library, and then make scientific and reasonable treatment countermeasures in combination with the actual situation of the disease.

Task management to control costs.

Highway maintenance and repair data platform should establish a sound inspection system and task system, according to the detailed data of the inspection system and task system, the relevant management personnel of the expressway.

Speed highway maintenance and repair data platform should establish a sound inspection system and task system, according to the inspection system and the detailed data of the task system, the relevant management personnel of the highway can develop a more scientific annual maintenance and repair task list, and on this basis, combined with the content and time of the task implementation, the optimal allocation of resources, according to the maintenance and repair task list has been developed to the maintenance and repair task of the implementation of the situation and the cost of comprehensive tracking, while mastering the completion of each task.

Now China has entered a peak period of highway maintenance and repair

China's land area is about 9.6 million square kilometers, and the water surface area is about 4.7 million square kilometers.

If only the land area is counted, 3300 960, or 33 million square kilometers, is about China; If the water area is included, 3300 1430, or 33 million square kilometers, is about China.

Expand your knowledge:China has a land area of about 9.6 million square meters, more than 10,000 kilometers of coastline in the eastern and southern continents, and more than 4.7 million square kilometers of inland and border seas. There are more than 7,600 large and small islands in the sea area, of which Taiwan Island is the largest, with an area of 35,798 square kilometers.
