Why do people call those lakes in Jiuzhaigou "colorful sea" and "colorful pool"?

First, people call those lakes in Jiuzhaigou "five seas of flowers" and "colorful pools" mainly from legends.

Legend 1

It is said that the goddess who fills the sky needs a lot of colored stones when needed. She was busy searching for these colorful stones for several days and nights before she found five colors of stones: red, yellow, blue, white and blue. She melted them, and after ten days and ten nights, the colorful stones finally turned into a very viscous liquid. Nu Wa put them in a big basin, lifted them to the horizon, aimed at the big black hole, threw them hard, and saw the golden light shining, and the big hole was repaired immediately. When she spilled the liquid, it fell to the ground, and every pit was a colorful lake. After being washed away by rain, it became thinner and thinner, and now it has become a colorful pool in Huanglong. A large piece of yellow liquid rolled down the hillside and covered the whole hillside, forming a golden color, and the waterfall exuded golden light. This is the famous Jinsha Building.

Legend 2

Jiuzhaigou landscape is unique in that it has 65,438+008 clear Haizi (locals used to call the lake "Haizi"). Legend has it that in a very distant era, the fierce male god Dago, the lover of the goddess Vornochem, gave her a precious mirror. Perhaps Wonuoqim was so happy that he accidentally dropped the mirror to 108, and this 108 became a colorful lake of 108, called "Cuihai".

Legend 3

There are colorful jade ponds in the palace of the Queen Mother, and the mountain wind is blowing, which is even more colorful. It really looks like a colorful jade pond falling into the world. It is widely rumored in the local area that this is dyed by the fairy's rouge.

Second, the scientific explanation says.

The real formation of most lakes in Zhaigou is related to calcium carbonate contained in running water. In that ancient time, the earth was in a very cold interglacial period and a little ice age, where calcium carbonate in the water could not condense, and they died with the water. About 12000 years ago, after global warming, calcium carbonate in running water became active. They cling to an obstacle as soon as they meet it. For thousands of years, it has accumulated more and more, and it has accumulated thicker and thicker. As people can see in Jiuzhaigou, it is a "Haizi" composed of a milky calcium embankment, which is called a dammed lake in geology.

The reasons for the different colors of colored pool water mainly come from:

1, CA2+, MG2+ and HCO3- which are common in pool water can also enhance short-wave light scattering.

2. The transparency of the pool water is high, and the grayish-white travertine and yellow-green algae at the bottom of the lake selectively absorb and reflect the transmitted light.

3. Scattering, reflection and absorption of solar light by pool water (sunlight or natural light is polychromatic light composed of monochromatic light with different wavelengths, and in the spectrum, the wavelength gradually decreases from red light to purple light).

4. Part of the surrounding scenery is in the shadow of water or reflected in the water.
