The province with the best geographical position in the agricultural era
Friends who like Qing dynasty blockbusters must be familiar with this sentence: "The lake is wide and ripe, and the world is full." Bread is the staff of life. No matter which dynasty, there is enough food and everything is easy to discuss! So where does Huguang mean?
In fact, to be precise, this statement first evolved from Su Hu's familiarity with the world. The main grain producing areas in China have experienced an evolutionary process. The main grain producing areas in Song Dynasty were located in Suzhou and Huzhou. As long as there is a good harvest in these two areas, the people of the whole country will not worry about food and clothing. The "Seven Manuscripts" compiled by Lang Ying, a bibliophile in the Ming Dynasty, recorded the statement that "it is enough for Su Hu to know the world"!
However, in the Ming and Qing Dynasties, this major grain producing area began to change. Farmland in Jiangsu and Zhejiang provinces began to mainly grow cotton, because this cash crop has a high profit, and the main grain producing areas gradually shifted to Hubei and Hunan, because Jianghan Plain entered the great development in Ming and Qing Dynasties, and a large number of lakes and beaches were reclaimed as farmland. With the improvement of agricultural production technology and economic level, it has gradually changed from "Suzhou and Shanghai are ripe, and the world is sufficient"
With the growth of population, there is no place to supply the whole country in the main agricultural producing areas. At the peak of the Ming Dynasty, the population of the whole country was about 60 million, close to 400 million in the late Qing Dynasty and close to 654.38+300 million at the beginning of 2000. Therefore, with the soaring population, there is no place to provide the main grain producing areas. According to the statistics of the article "Changes in the Regional Pattern of Grain Production in China since 1990s" published by Chinese Academy of Sciences, from 190,
Regional changes and statistics of major grain producing areas
Therefore, from the geographical position in the agricultural era, it is of course more complementary to share food security from Su Hu to Huguang and then to many parts of the country.
The province with the best geographical position in the era of globalization
Since the end of Qing Dynasty, China has entered the global trade circle, but in the current era of globalization, China's economy is closely integrated with global trade, so in the era of globalization, trade is an unavoidable hurdle! In the era of trade, the port is of course the most important. Although land and air transportation can be an excellent supplement, the throughput of the port is a journey!
Therefore, in the era of global trade, ports are the most important!
Where is the best port in China? There is no doubt that it is Shanghai Yangshan Port, a port directly built on the rugged archipelago in Shengsi County, Zhejiang Province at the mouth of Qiantang River. The main part is on Xiaoyangshan, with a port area of 2. 14 square kilometers. Since its completion, the container throughput of Yangshan Port has soared, becoming the largest container terminal and the busiest container port in the world!
20 19 Top 10 container ports in the world: Shanghai Port (1), Singapore Port (2nd), Zhoushan Port of Ningbo (3rd), Shenzhen Port (4th), Guangzhou Port (5th), Busan Port (6th) and Qingdao Port of Shandong Port (7th)
Among the top ten ports in the world, China has seven seats. In fact, from the perspective of geographical location and port conditions, Ningbo Port is actually excellent, but it is inferior to Shanghai in port construction. But no matter which one, it is our own!
The province with the best geographical position in space age
Mankind has gone all the way from the agricultural era to the era of industrialization and global trade, and will certainly continue to move towards the space age in the future, which is the only way for human civilization. So in the future space age, which province in China will occupy an absolute advantage?
There is no doubt that Hainan is the first choice.
Why Hainan? China's manned space base is Jiuquan, and its satellite launch centers are Xichang and Taiyuan. Why did Hainan come out? In fact, this is determined by the modern rocket launching principle!
At present, the mode of entering space is to use rockets to accelerate satellites or spacecraft to the first cosmic speed. At this time, the "centrifugal force" of the rocket around the earth is equal to the gravity it receives, so the spacecraft will make a circular motion around the earth! This speed is about 7.9 km/s, and the earth's rotation speed is about 465 m/s (equatorial linear speed), so launching from west to east on the equator can save 465 m/s acceleration and save a lot of fuel!
If launched at high latitudes, the orbit has an inclination in order to move around the center of the earth, and this component will decrease with the increase of latitude. If launched in the North Pole, the speed increment of the earth's rotation will be zero, so it is an inevitable choice to choose a rocket launch base with low latitude.
Hainan Wenchang space launch site
The latitude here is19 36' 52.10 "n, although it is not at the equator, it is the place with the lowest latitude and the most complete supporting facilities that China can find. Therefore, the future manned moon landing, deep space exploration and manned Mars program will all be implemented here, and the turning direction after its launch will be a sea of Wang Yang, and the separated first-class rocket will splash into the sea, affecting it.
Therefore, from the location of the space port, Hainan is the best!
