Nature is natural artist

Some time ago, near the Jiashao Bridge near Haining

Qiantang River enter Haikou

I have created a freehand "ink painting roll"

A towering tree

Skinchi

Long on the beach

Winding texture

Like Jupiter surface

As if there is an interstellar crossing

Why does this scene appear in Haikou?

Behind this is actually a geographical class

According to experts from the Zhejiang Provincial Department of Natural Resources, the "tide tree" is not a certain plant, but a strange phenomenon in the tide belt landform. The tidal band landform refers to the part between the average low tidal line and the average climax line, and the "tidal tree" is a unique phenomenon in the tide beach (silt beach).

Generally, the "tide tree" is formed, and two conditions need to be met:

First, the internal cause, that is, the texture of the tide beach where the "tide tree" is located is easily eroded, and generally the sediment content is high;

The second is the external cause, that is, the external hydraulic effect is needed. The "tidal tree" is generally accompanied by the "growth" of the tidal effect. When the tide rises and the tide is brought and out of the sediment, the tide grooves that are scratched day after day will become deeper and more deeper and deeper. The longer and longer, forming the main trunk of the "tidal tree", continuously extending to the inland.

At the same time, under the action of side erosion and traceability erosion, the "tidal tree" gradually leafy leafy, forming a "towering tree".

In other words, the formation of "tidal trees" is a kind of sedimentary landform affected by the tide of seawater. In the process of rising and falling, it is also a natural phenomenon. Sometimes when the seawater impacts ashore, it will bring seaweed, growing on "branches", and looks like "leaves". "It is more ornamental, and the‘ picture ’formed by the tide is also dynamic. There may be a difference from what you see tomorrow.”

According to reports, "tidal trees" appear more in coastal places such as Liaoning, while Zhejiang coast is relatively rare. "In the picture I took this time, the gray one is actually silt, and the formation of 'tidal trees' is also related to the amount of mud."

Experts say that there are many near -sea farming in Zhejiang, there are certain human intervention, and the "mud content" is relatively small, which affects the formation of "tidal trees" to a certain extent.
