Dinghai is Zhao Xin's thousands of choices, and the final selected place for development, location and area, are relatively suitable, without a reasonable location, it will not be able to play a huge commercial and transportation value, as for not enough land, even a large factory can not be accommodated, let alone a huge population.

In the previous Zhao Xin's positioning, it was set as a large-scale industrial city and commercial center, this positioning is very high, Zhao Xin is to treat Dinghai as the future of Shanghai, which is a country's commercial and manufacturing leader.

In terms of geographical location, compared with Shanghai, the Dinghai Navy has no other problems except that it does not have a waterway in the Yangtze River basin, and even has certain advantages.

It is also a port, and it is quite close to Hongze Lake, the terminal of the Huai River, as long as it takes a certain amount of effort to dig a 300-mile-long waterway to solve the problem of Hongze Lake entering the sea, and further combine the core water system of the Northern Song Dynasty with him, and the linkage of river transportation and sea transportation will eventually create good results.

When he first chose a place to stay, Zhao Xin also considered Shanghai, but in the end, the reason for not deciding Shanghai was very simple, that is, the existing situation.

In the Northern Song Dynasty, except for a small part of the southern part of the Yangtze River, most of the areas, such as Hunan, Hubei, and Sichuan, are still an undeveloped place.

In fact, to promote the development of Jiangnan, it was not until the period of the Southern Song Dynasty that the Jin State broke through Bianliang and destroyed the Northern Song Dynasty, and the emperor of the Southern Song Dynasty crossed directly to the south and opened up a new dynasty in the south of the Yangtze River.

It was a miasma land, but because of the population and the administrative orders of the imperial court, it was developed, only more than a hundred years, but it laid the foundation of Jiangnan, and really shifted the center of gravity of the entire feudal dynasty from the north to the south, and thus laid the foundation of the future south.

Hundreds of years later, the Ming Dynasty, which was the Yuan and Mongolian, and the Han people regained sovereignty, was the unified dynasty from the south to the north in the entire Chinese history, and established the regime.

Even if the southern regime, in the beginning, was stronger than the northern regime, and could even sit on the hill and watch the northern melee fight, once the north was reunified, the south would not have the slightest chance of being reunified, and it was only a matter of time before it was reunified.

Now, the Northern Song Dynasty has not yet crossed to the south, and the development of the south of the Yangtze River is still developing slowly, even if Zhao Xin forcibly developed Shanghai, Shanghai also has this heritage to develop, but it is too far away from the center, from the most densely populated area of the entire Northern Song Dynasty, which is a natural disadvantage, if it cannot be changed, it is quite unfavorable for development.

It is too early to say Shanghai now, in the future, perhaps when Zhao Xin has laid the foundation, these coastal ports will be developed, and they will be developed at the mouth of the Yangtze River, which can radiate most of the southern Shanghai, and the natural geographical advantages are not changed, and he will inevitably become a large port.

In the extreme era, Shanghai almost occupies more than half of the entire industrial output value of China, made in Shanghai is not only a brand, but also a production capacity, and the same is true of the Dingjun under Zhao Xin's arrangement, and even with the blessing of Zhao Xin's technology, the cooperation of the card system will be even more terrifying.

Unconsciously, it has been 2 years since the crossing, from the confusion that has just passed, to the current clarity, Zhao Xin has a feeling of being separated from the world, a city that can be called modern, full of industrial charm and fast-paced in the 11th century, in less than a year, rose in the Yellow Sea, this sense of achievement is indescribable.

Starting from Miaojiazhuang, and then laying the foundation of the Daimyo's Mansion, it is unceremonious to say that the development of the Dinghai Navy is much faster than Zhao Xin's estimate, and the victims from Huainan East Road are a huge test.

But Zhao Xin's strength is much stronger than it shows, not to mention 300,000 victims, and even twice as much can accommodate it, after obtaining orders from the Privy Council and the Third Division of the Northern Song Dynasty Iron and Steel, plus other industries, Zhao Xin has a lot of funds in his hands, and by sea transportation, as long as enough rice is transported from Jiangnan, it is enough to feed these people.

In this desperate situation, as long as someone gives him a bite to eat, let alone such work, hard work, even if it is murder and arson, and give their lives, they are willing to do it, no one thought that this escape from the famine will become a place to change their fate.

The huge population has made the Dinghai Navy develop faster than expected, and in a year's time, Zhao Xin estimated that the labor force of the Dinghai Navy can reach 400,000, which is already good, but now, it is 1.2 million, which is three times.

Triple population growth does not bring three times the expansion of production capacity, that is more than 10 times, industrialization, the production efficiency of a single person, very high, the rapid development of the Dinghai Navy, there are already signs of a metropolis.

Urbanization is the foundation of an industrialized country, a country where eighty percent of the population is peasants, and no matter how strong the industry is, it is limited.

A city with a population of one million, it sounds like a lot in the 21st century, a million people, can no longer be called a big city, but in the 11th century, in the whole world, there is only one Bianliang, and then more than a hundred years later, Lin'an was added, which is still after absorbing the relics of the Northern Song Dynasty.

It took less than a year for the Dinghai Navy to do something that other cities may not have done in a lifetime, and once this population explodes, it will definitely surprise many people.

Of course, Zhao Xin will not publicize, any action that may touch the nerves of some people, he will not do it, Ding Haijun will definitely shock the whole world, now, it is better not to show it.

The appearance of cement and steel bars, and some six- and seven-story buildings, made the population of Dinghai exceed 1.2 million, but they are not conspicuous at all.

In the Northern Song Dynasty, even if it is Bianliang, the population density is not very large, according to the length of the city wall of Bianliang dozens of kilometers to calculate, the area of Bianliang City, at least more than 100 square kilometers, in fact, plus the surrounding villages, because of the formation of some settlements similar to towns in the Gyeonggi belt, the area of the core area of Bianliang is far larger than the city wall, with a population of one million, including the permanent population and the garrison.

Even if it is calculated according to a city of 1 million people and 100 square kilometers, the population of each square kilometer is about 10,000 people, and the population density cannot be considered low, but it cannot be regarded as high.

In later generations, that is, the size of a medium-sized city, if you deduct the large number of garrisons, the population of Bianliang is not very large.

Why, in the Han and Tang dynasties, there were no million-scale cities, even if it was Chang'an in the Tang Dynasty, that is, hundreds of thousands of people, huge cities, the pressure on a kingdom was huge, and only a truly rich country could form such a terrible city.

The Northern Song Dynasty learned the lessons of other dynastic changes, not only used the method of releasing military power with a glass of wine, seized the military power in the hands of the generals, reduced the influence of the generals in the army, and replaced the generals with the Privy Council to control the army.

In the Northern Song Dynasty, through the development of the method of using strong trunks and weak branches, a large number of forbidden troops were concentrated in Bianliang.

The 800,000 forbidden troops of the Northern Song Dynasty were basically stationed in Bianliang, which was their natural station, and over the years, with the rise of war, especially the border troubles in the northwest, a lot of them were transferred out one after another, but there were more than 500,000 people stationed in Bianliang all year round.

If the 500,000 forbidden troops are deducted, as well as those family craftsmen who are dependent on the forbidden army, the million population of Bianliang may be reduced by 6 or 700,000, and the rest is only 3 or 400,000.

In this way, in the core urban area, each square kilometer is about 3000-5000 people, which is higher than the traditional feudal city, but the height is limited, Bianliang with a huge city scale, accommodating a million people, Qingming Shanghe map is to show the scenery of the Northern Song Dynasty.

At any time, the density of the army is the largest, a family, at least a few houses, a courtyard, the Northern Song Dynasty rarely has high-rise buildings, even in the prosperous area of Bianliang, for example, the famous Fan Tower, is known for its tallness.

Fan Lou such a high-rise building, in the era of no cement, no reinforced concrete, the cost of construction is also very high, simply build the main beam of Fan Lou, those wood that can almost build a palace, each is expensive, that is not ordinary people can afford to build, most of them are bungalows, so naturally restricting the population density.

But it is different in the army, a large shop, a tent, there are more than ten or twenty people, which is unimaginable in an ordinary family, maybe a plot of land that can only accommodate tens of thousands of people, can accommodate hundreds of thousands of troops, the population density in the barracks, far higher than the city.

Dinghai is an island with several hundred square kilometers of land, aside from some places that are not suitable for construction, the entire Dinghai Navy is planned to be more than 8 percent, that is to say, the entire Dinghai Navy has almost 300 square kilometers of land.

At present, the population of 1.2 million is concentrated in the urban area near the port, according to the standard of 80,000 people per square kilometer, which is difficult to achieve in feudal society, in the Northern Song Dynasty, the population density is not a problem at all.

According to a family of three, living in a 70 square meter of two bedrooms and a living room, a 1,000 square meters of residential land, excluding the common area of almost one floor is equal to 10 households, a total of seven floors, at least 70 households can be accommodated, according to the average of a family of four, 1,000 square meters of residential area, the population is about 280 people.

One square kilometer of land, 1 million square meters of land area, according to this ratio, is enough to accommodate 280,000 people.

Of course, it is impossible to plan for the planning of the city to 280,000 people, which is an outrageous density, so to speak, the degree of people everywhere, it will be very scary, some dense phobia, and even get sick.

However, 60,000 people per square kilometer can still be achieved, which is 10 times the degree of Bianliang, in the popularization of small apartments, the replacement of small houses with units, the reduction of yards and other costs, and the use of higher floors to bring greater population capacity, this seems to be very harmonious.

At present, the Ding Navy has a population of 1.2 million, and the core residential area centered on the port has been developed about 20 square kilometers, and the core of the entire Ding Navy, the port, the residences, and most of the factories are concentrated in this area.

It sounds like there is still a lot of area to be used in the Dinghai Navy, 20 square kilometers, compared to the entire Dinghai Navy, which is close to 300 square kilometers of land, there is a lot of unused land.

But a railway, according to the isolation of 150 meters on both sides, the railway of the simple 40-kilometer ring line occupies more than 12 square kilometers of land, and the vertical and horizontal roads also occupy a large area, in order to avoid future urban problems, Zhao Xin in the construction of the road, the reserved area is huge, the distance between the two sides of the street, at least more than 80 meters, it is impossible to use a very spacious road now, but it can give enough area to the sidewalk, with a method similar to the square to reserve.

These are huge areas, but in fact, the largest ones are the ironworks.

The Northern Song Dynasty could not reach the 21st century, the modern steel complex, with higher and more intelligent control, reduce the area of the steel plant, this era, no machines, no automation, every blast furnace, not only the blast furnace itself, he includes all the surrounding ancillary buildings.

An iron-making plant with an annual output of 2.2 million tons, all kinds of blast furnaces of all sizes, nearly 100, and the area of the iron-making plant alone is as high as 60 square kilometers, which has occupied one-fifth of the area that can be used by the entire Ding Navy, so to speak, a steel plant occupies most of the city.

In addition to the ironworks, after coming to the Ding Navy, some other large factories were built, such as cement factories and ceramic factories, which occupied most of the space of the Dinghai Navy, and left about 50 square kilometers of reserved space, but they were not suitable for rash investment.

This is also a matter of no way, the Ding Navy is too small, the future positioning, is also a commercial center and a simple industrial base, this industry, basically, does not include heavy industry and chemical industry, even daily chemicals, the future needs to be stripped, the reason is very simple, it is not that the Ding Navy does not need these light and heavy industries, but the positioning of the Ding Navy in the future, these are a bit chicken ribs for the role of the Ding Navy.

Industry, at any time, has a huge role for the city, but a pollution problem, is a problem that is difficult to overcome, for the more developed the city, the more so, not to mention the utilization rate of the huge city, there is no way to accommodate large-scale factories and mines.
