Why is the water of Taihu Lake so stinky?

The air smells like water.

It may be that the water source is insufficient, otherwise it would not be so shallow, but many people say that the water source of Taihu Lake is quite large, with an average annual runoff of 7.5 billion cubic meters and a water storage capacity of 4.4 billion cubic meters.

It stands to reason that a lake as large as Taihu Lake should have a high water storage capacity, but its water storage capacity is only 4.4 billion tons. In contrast, the famous Changbai Mountain Tianchi.

Just a crater lake, the area of Changbai Mountain Tianchi is less than 10 square kilometers.

However, the water storage capacity has reached 2.5 billion tons, which is almost half the size of Taihu Lake.

Introduction

In fact, Changbai Mountain Tianchi is very deep, because it is a volcanic crater, the main source of water is natural precipitation, the average water depth of Tianchi reaches 204 meters, which is the deepest average depth among China's natural lakes. Changbai Mountain Tianchi is considered to be the Songhua River.

One of the sources, the water of the Heavenly Pond will also overflow outward. The reason why the water storage capacity of Taihu Lake is so low is that it is simply too shallow. The average depth of the lake is less than 2 meters, and the deepest part of the lake is only 4 meters, which is simply outrageously shallow.

Among the top 10 lakes in China, Taihu Lake is the shallowest one. If you look at the size of Lake Ether all over the world, it is estimated that there is no shallower lake than it. What is causing this phenomenon?

Some believe that this may be how Taihu Lake was formed. The left half of the lake is a perfect semicircle, so it is likely that the lake was born from a meteorite impact.

Taihu Lake is the largest shallow lake in the Taihu Lake Basin, with an average water depth of one meter and a maximum water depth of less than 4 meters, with a catchment area of 2,338 square kilometers, a length of 68 kilometers and a width of 56 kilometers.

Many people say that this is related to the initial formation of Taihu Lake, while others say that the bottom of the lake is full of nutrient-rich silt, and as long as the sun shines directly in summer, cyanobacteria are easy to explode, so the water depth of Taihu Lake is so low.

It may be that the water content is insufficient, otherwise it will be so shallow if you don't make trouble, but many people say that the water source of Taihu Lake is quite large, with an average annual runoff of 7.5 billion cubic meters and a water storage capacity of 4.4 billion cubic meters, but the water depth is so low It feels a bit abnormal.

Many people say that this is related to the initial formation of Taihu Lake, and some people say that it is due to the thick layer of nutrient-rich silt at the bottom of the lake, as long as the sun shines directly in summer, cyanobacteria are very tolerant and easy to multiply, so the water depth of Taihu Lake is so low.

1.Global warming.

It is the world that is changing, not only Taihu Lake is changing, Wuxi is changing, but there is a problem with the water of Taihu Lake, the water in Wuxi can not be drunk, the problem is not in global warming, otherwise, the water in the world will stink.

2.The issue of global warming mentioned in the article is only written in the subtitle of the article: "Experts say global warming is due to cyanobacteria in Taihu Lake."

The main cause of the early outbreak.

The local government has stepped up the introduction of water from the Yangtze River to improve the water quality of Taihu Lake", however, in the subsequent narrative, it is described as follows: "Experts point out that the excessive temperature of the lake has led to an early outbreak of cyanobacteria, and if no timely response measures are taken, the area of cyanobacteria in Taihu Lake will become larger and larger, and the spread will continue throughout the summer". Other experts only said that the high temperature was one of the reasons, without the slightest mention of global warming, distorting the meaning of others, such people are shameful, distorting the meaning of others, and publishing it on the Internet**, it is even more shameful.

What is the reason why the water of Taihu Lake stinks? The root cause is algae in Taihu Lake.

Mass propagation, i.e., eutrophication.

Phenomenon. The cause of algae blooms is the excessive amount of nitrogen and phosphorus nutrient precursors in the water. In recent years, a large amount of domestic sewage and industrial wastewater have been discharged into rivers and lakes, and the nitrogen and phosphorus nutrients in the water have increased significantly.

This led to the bloom of algae, forming a "bloom" in the lake, which is the amount of green algal material we see in the lake; Red tides form within the ocean.

We also hear about it a lot.

4.Global warming will increase temperatures, which will exacerbate eutrophication. But this is not a phenomenon that leads to eutrophication, if there is no water pollution.

There are no nutrients such as nitrogen and phosphorus in the water, even if the global temperature rises to 100 and the water on the earth is opened, there will be no eutrophication, the water of Taihu Lake will not become stinky, and the people of Wuxi will not suffer.
