The shape of the trees in the sky formed on the Qiantang River is related to the tides of the Qiantang River. This phenomenon occurs every year when the Qiantang River is at high tide. The locals call it the tide tree, and nature is simply breathtaking. This so-called tidal tree has nothing to do with plants. It is a tidal ditch formed by river scouring and belongs to sedimentary landform. This scene was shot by a photographer through a drone. Tidal tree phenomenon is quite common in Jiangsu coastal areas, where the geological structure is relatively complex, and the structure of tidal forest has been formed, and the tide has a great impact on the ecosystem.

The reason why the towering trees appeared. Qiantang River is located in Yan Guan Town, Jianghai Ning County, Zhejiang Province. Since ancient times, it has attracted many people to watch. From the first day to the fifth day of the lunar calendar, from 15 to 20, you can see the tide rushing to the shore. August 18th of the lunar calendar is the biggest spring tide in Qiantang River every year. At this time, the waves of Qiantang River are rolling, and the distant tide is coming to people like a white line, which is very spectacular. The spring tide in Qiantang River is actually related to the gravity of the moon. When the celestial bodies run, the sun, the moon and the earth will be in a straight line, and the moon will have the greatest attraction to the seawater, and the seawater will roll.

The reasons for the formation of tidal trees. The conditions for the formation of tidal trees include: the coastal soil is related to tidal force, and the soil is soft and vulnerable to tidal erosion. The long-term erosion of tides will change the accumulation form of sediment in soil, resulting in gullies of different sizes and depths, thus forming this phenomenon. Tides have a great influence on the ecosystem. First, the evolution of organisms. It is precisely because of the tides that fish landed on the land from the water, thus evolving a variety of creatures on the land. Many marine animals will migrate according to the direction of the tide to find a more suitable environment for survival. Tides will accelerate the stability of ocean temperature, and the cold water at the bottom of the ocean will rise to the surface of the ocean, thus delaying the possibility of large-scale algal blooms.
