Why does Guangzhou "choose to live high" in Jiangzuo?

On the issue of urban location, most big cities are located on the right bank of the river. Many friends are skeptical: the north bank of the Pearl River is on the left side of the river, while the south bank of the Pearl River is on the right side. According to the ancient concept that the right side of the river is good and the left side of the river is bad, shouldn't Guangzhou be centered on "Henan"? Did the ancients choose to plan Guangzhou against common sense? This is because the landscape environment in Guangzhou is quite complicated and unusual, and it is impossible to simply use the concept of "left river and right river" to distinguish which side of "Henan and Hebei" is more livable.

There are many hills and terraces on the north bank of the Pearl River.

The price of soapy water is the source of life and an indispensable element and resource for human production, life and transportation. It is human instinct to choose water for survival. Feng Shui also believes that "there is no water on the ground", and villages and cities should be selected "until there is water". The water environment in Guangzhou is very special and unique. In other big cities in China, there is generally only one big river passing in front of or beside it. In this case, the area on the right side of the river is usually more livable than the area on the left. Guangzhou is located at the intersection of Dongjiang River, Xijiang River and Beijiang River, which belongs to the water gathering pattern of "turbulent flow like brocade, prosperity regardless of long distance transportation".

In ancient times, the Pearl River was very vast and tidal, so Cantonese called it "Zhuhai", not the Pearl River. Crossing the river is called "crossing the sea". Due to the constant threat of tides, people have to "choose the highest place to live". Located on the tall Baiyun Mountain, the north bank of the Pearl River is a hilly, terraced and plain area with relatively high terrain. There are only plains and terraces on the south bank of the Pearl River, and there are no hills, so the ancients chose to build their capital on the north bank of the Pearl River. Bu Zhi, the secretariat of the State of Wu, inspected the geographical environment of Guangzhou. He looked up into the distance. "Look at the vast sea and the port of Yinzhou." Nai: The fertile land of Sicheng Island should be the capital city. "So on the basis of burning the city, Guangzhou City was rebuilt.

The topography on the left side of the river gradually decreases from north to south.

In the long-term urban construction practice, the ancients also summed up a law, that is, the geographical environment of the city is "negative yin and yang", and the balance of yin and yang is the best environment. Geographers believe that mountains are still life and belong to yin; Water is a moving object and belongs to Yang. The so-called "negative yin embraces yang" means being in an environment where there is water on the back of the mountain and water around the mountain. Therefore, the ancients said that "water around the mountain must have gas." The base of the city is best located in the middle of the mountain pattern, with a flat terrain and a certain ramp. The geographical environment on the north bank of the Pearl River meets these requirements. Not only is it "facing the sea with its back to the mountain", but the terrain gradually decreases from north to south. Building a city here has mountains on one side and water on three sides. Mountains stop water from gathering, and yin and yang are balanced. Feng Shui believes that "mountains dominate your wealth and water dominates your wealth", so the north bank of the Pearl River can be both a political center and an economic center.

In contrast, "Henan" on the south bank of the Pearl River is surrounded by water, with low terrain, plenty of water and thin mountains. In addition, water flows clockwise to the right, with more yang and less yin, so it can become an economic hub but not a political center. Therefore, the ancients chose "Hebei" to build a city for political and economic reasons.

As a big city, it must have a hinterland large enough to meet the needs of the expanding city scale. According to the size of the relatively closed geographical environment unit, geo-informatics can be divided into "large gathering", "medium gathering" and "small gathering". It is considered that "Daju" should be the capital and "Zhongju" should be the county G.

Scientific research shows that the right bank of all rivers in the northern hemisphere is seriously washed by the current, while the left bank is slightly washed by the current, which is caused by the "right bias force" produced by the earth's rotation. Sediment washed down by hills and streams in mountainous areas, and sediment in the three rivers are deposited on both sides of the Pearl River. Under the influence of the "right deviant force" of the earth's rotation, the sediment on the north bank was slightly washed by the current, and accumulated over time to form a "accumulation plain". The natural accumulation on the south bank is washed by the Pearl River water and tide, and the deposition is very slow. Therefore, after the Song Dynasty, the north bank of the Pearl River moved southward rapidly, and the Xicheng in the Song Dynasty, the New Town in the Ming Dynasty and the Thirteen Lines in the Qing Dynasty were all built on the "accumulation plain". Now Jiangyan Road, Yide Road, Daxin Road, Dade Road and Huifu Road. In ancient times, it was the "seabed", but now it has become a densely populated and prosperous area, which proves that the northern shore of the Pearl River is more conducive to the formation of a vast hinterland and the expansion of Guangzhou.

Haizhu Island from "Henan" to "Hebei"

Due to the erosion of the Pearl River tide, the south bank of the Pearl River moves northward at a much slower speed. In the past 300 years, the river bank has not extended to 100 meter. Haizhu Island in Song Dynasty, because it is close to the south bank, has always been regarded as a place belonging to "Henan". In modern times, with the southward movement of the northern shore of the Pearl River, Haizhu Island is getting closer and closer to the northern shore. 193 1 year, due to the need of land use, people filled the narrow branch between Haizhu Island and "Hebei" mainland, and the southern edge of Haizhu Island became a long embankment. Since then, the beautiful Haizhu Island has disappeared from people's sight.
