It seems that the main way to cure floods is to build water conservancy projects, which are not cured by the root cause. There are many reasons for this flood, but in Zhao Gang's view, there are several reasons that must not be able to escape. One is that the desertification is severe and the greening is insufficient, which has caused soil erosion. The other is that the flood area has been artificially reduced, and the lake that could have accommodated many floods has been surrounded by heaven and earth.

In view of this, Zhao Gang decided to carry out the greening project-Three North Shelterbelt Engineering University, also known as the construction of the Green Great Wall. The project is located in areas with severe wind and sand hazards and soil erosion in the northwest, North China, and Northeast China. It is a large-scale shelterbelt project, namely the "Green Great Wall" that combines belts, slabs and networks.

The planning scope includes 324 counties (banners) in Xinjiang, Qinghai, Ningxia, Inner Mongolia, central and northern Gansu, Shaanxi, northern Shanxi, and western regions of the three northeastern provinces, with 44 million rural populations and a total area of ​​3.9 billion mu. In order to lock in wind and sand and reduce natural disasters.

The Three North Shelterbelt System Project is a grand ecological construction project and a great feat in the history of world forestry development. It has set a precedent for forestry ecological engineering construction. It spans the western part of the northeast, northern China and most of the northwest areas, including 13 provinces in northern my country (autonomous regions, 551 counties (banners, cities, districts). The construction scope starts from Bin County in Heilongjiang Province in the east and ends at the Wuzibeli Pass in Xinjiang Uygur Autonomous Region in the west, with a total area of ​​4,480 kilometers east and west, with a total area of ​​406...| times.

In this land that was once densely forested and fertile grasslands. Due to the effects of various man-made and natural forces, the vegetation here has been damaged. The land has desertified and soil erosion is very serious. There are eight major deserts, four major sands, deserts, Gobi and desertified land in the area reaching 1.49 million square kilometers, extending from Xinjiang to Heilongjiang, forming a line of wind and sand.

On the Loess Plateau, the area of ​​soil erosion accounts for 90% of the total area of ​​this area. In some areas in the lower reaches of the Yellow River, the riverbed is 3-5 meters above the ground outside the embankment, becoming a "hanging river" on the ground. The average annual precipitation in most areas is less than 400 meters. It has formed a climate characteristic of "nine droughts in ten years, and if there is no drought, it will flood." The harm of wind and sand, the ecological harm brought by soil erosion and drought seriously restricts the economic and social development of the Three Norths, leaving people of all ethnic groups in a poverty-stricken and backward situation for a long time, and also poses a severe challenge to the survival and development of the Chinese nation.

If greening is successful, China's ecological environment will improve greatly, resulting in less floods and losses caused by raging floods and reduces accordingly. However, the difficulty Zhao Gang has to face is where to find water areas.

In the Three Norths, the average precipitation is only 500 meters. Most of them are concentrated during the flood season and cannot be effectively utilized. It is unrealistic to rely solely on local water resources to green. A sapling requires a lot of water to promote growth. If there is no sufficient water, the tree cannot grow. But where does the water come from?

"South-to-North Water Diversion"? Just kidding, the South-to-North Water Diversion is for people to use, and it is just that, and the cost is quite high. If you give a tree, then it will not be enough. Zhao Gang thought for a long time but couldn't figure out what to do, so he had to ask for opinions from others.

As a result, in less than ten days, countless plans were collected, including those who exploded Mount Everest and melted snow water, those who dug deep wells to grab groundwater, and those who were artificial rainfall in the sky. However, one plan was still feasible, and the others were short-term behaviors. It was not advisable.

This report, called Selenge River irrigation project analysis, explains in detail how to reverse the Selenge River. Selenge River originates from the northern slope of Hanai Mountain in Mongolia, called the Idel River. It flows through northern Mongolia and injects into Baikal Lake in Russia. It is one of the sources of the Yenisei River-Angara River. It is 1,024 kilometers long and has a basin area of ​​945,480 square kilometers. Hanuyi River and Orhung River flow from the right bank, and the water flow is slow and the drop is only 35 meters. The Deleger River and Eji River flow from the left bank. The water flow is rapid, and the drop of the river bed is

This plan is to completely reverse the river water and form a huge irrigation project radiating to the Three Norths. Its spirit is amazing. If this project is completed, it will provide 65 billion tons of water every year, which is equivalent to building a new Yellow River.

The total source of this plan is that Lake Baikal is the largest freshwater lake in the Eurasian continent. It is kilometers long and has an average width of 50 kilometers. It is the seventh largest lake in the world and the deepest in the world: it contains one-fifth of the entire freshwater of the earth (which should refer to the freshwater of rivers and lakes). It is equivalent to the total water volume of the five major lakes in North America. Even the annual extraction capacity of 65 cubic kilometers is nothing compared to the lake capacity of 23,600 cubic kilometers. Lake Baikal is 650 yuan at an altitude of 650 yuan, which is more important than the lake capacity of 23,600 cubic kilometers.

Compared with the altitudes of the Three Norths that need irrigation, there is not much difference and does not need to be too high.

However, the funds required for such a large project are also very huge. More than a dozen huge step-type pumping stations are responsible for pumping water to the source of the Selenge River, where they are transported to other areas through four main channels. Although 87% of the places do not require construction, the other 13% of the road sections are also an extremely huge number, and a 2,300-mile canal is needed to be built.

Zhao Gang thought of "Zheng Guoqu". In the late Warring States Period, Duke Huan Hui of Han saw that it was a general trend for Qin to unify the six countries. In order to weaken the powerful strength of Qin, in 237 BC, he specially sent the South Korean watercraft Zheng State to Qin to build water conservancy, trying to use this huge project to consume Qin's manpower, financial resources and material resources, so as to achieve the goal of "exhausting Qin" that he expected!?

Unexpectedly, the Qin King Ying Zheng (later Qin Shihuang) adopted the suggestion of Zheng State and ordered Zheng State to build the Zheng State Canal in Qin State. Under the personal command and participation of Zheng State, a large-scale water conservancy project of 100 kilometers, the Zheng State Canal winds and circulates on the land of Guanzhong, as if a golden silver belt was spread on the land of Sanqin.

It cleverly utilized the terrain characteristics of the southern foot of Beizhong Mountain, which was high in the west and low in the east and low in the east, and built the canal on the highest line of the three-stage staircase of the Weibei Plain, irrigating 2.8 million acres of land in Liquan, Jingyang, Sanyuan, Gaoling, Lintong, Fuping, Weinan, Pucheng, Dali and other counties. The Zheng State Canal not only failed to play the original intention of "exhausting Qin", but also greatly enhanced the national strength of Qin. This made the originally powerful Qin State like a tiger! It even faster the realization of its dream of eliminating the six countries.

The Zhengguo Canal Project is magnificent and large in scale, which can be regarded as a feat of more than two thousand years ago. It used the fertile Jinghe mud water to irrigate the fields, silt fields and press alkali, turning the swamped saline and alkali land into fertile and fertile fields, making Guanzhong the richest area in the country. According to the Records of the Grand Historian, after the construction of this canal, "So Guanzhong was fertile and had no bad years." This made material preparations for Qin Shihuang to finally unify China!

If this new Zhengguo Canal is built, it will probably take about fifteen years. During this period, China can only defend, conduct local attacks, and cannot make a full attack. However, after fifteen years, nearly 500 square kilometers of land in the Three Norths will be turned into fertile fertile fields, and then further radiate to Siberia, and develop Siberia can obtain nearly ten million available territory.

The bright prospects made Zhao Gang understand that the new generation of Zheng Guoqu is the wealth he left to China. Even if it fails temporarily, it can leave this extremely huge treasure land to his people. So after half a year of discussion, the new Zheng Guoqu plan was approved. This plan was named the China Canal Plan.

In the Three North Greening Project, nearly 10 million people fought in the Three North Shelterbelt Project and began the battle to conquer nature by man. In addition, greening work has also begun in the south. Compared with the north, these places do not need to mobilize water sources, but only need to appropriately return farmland to forests to effectively increase the greening area. Therefore, it is not recorded in the coordinated greening, resulting in the regulation that it is enough to reach an indicator in ten years.

Soon another person put forward a feasible suggestion. The Yarlung Zangbo River water diversion plan, and the Yarlung Zangbo River has a huge water volume, which is more than three times the water volume of 140 billion rivers in the Linzhi section, which is more than six times the total inflow rivers in China, and three times the current total water volume of South-to-North Water Diversion.

China controls the desert and develops the northwest, which can lead to the water of the Yarlung Zangbo River. Once the Yarlung Zangbo River water enters the northwest, it can make the four major basins in northwest China, the Tarim Basin, Turpan Basin, Qaidam Basin, Junggar Basin, and Hexi Corridor. The yellow sand here will no longer exist, becoming the south of the Yangtze River outside the Great Wall where "the fragrance of rice flowers says good fortune and the sound of frogs is heard", and at least solves the problem of eating for hundreds of millions of people. The climate in northwest China will also change, and the evaporated abundant water vapor will completely change the precipitation in northwest China.

This project has been proven and is also very feasible, and it has a cost (the original plan was 1,250, 20 fiscal revenue in 2015, and the total GDP in two years)

After 1904, China's large-scale water conservancy construction began to study the intentions of the Chinese. In any case, Britain and Germany were secretly happy. Doing this was equivalent to declaring the fight for world hegemony and focusing on domestic affairs. In order to fight for world hegemony, Britain and Germany began a more intense confrontation.
