Why is Lake Namco getting bigger and bigger?

king

(1) Since the beginning of this century, herders living on Namco Lake have found that Namco Lake is approaching their place of residence bit by bit, and even some herders wake up and find that their homes are adjacent to the lake. In this regard, there are various opinions among herders. Some people say, what is this? Tianhu? God was angered. Because the herdsmen did not pay attention to hygiene, the fairy Namco, who always loved cleanliness, became angry, and the lake rose, flooding the people by the lake. Others said that the gods in the sky were angry, and there was too much rain, so the lake naturally rose.

② The rising of Lake Namco has attracted the attention of not only the local government and herdsmen, but also scientists. Through observation, the staff of Namco Comprehensive Observatory of Qinghai-Tibet Plateau Research Institute of China Academy of Sciences found that the water level of Namco rose by 7 meters from 1970 to 2009, the elevation of the lake changed from 47 18 meters to 4,725 meters now, and the capacity of the whole lake increased by nearly1400 million cubic meters.

③ Why did Namco Lake suddenly rise? Where does the increased water come from? With these questions, let's look for information, visit villagers and experts, and uncover the truth behind the problems.

④ In Tibet, the most significant change brought about by global warming is the melting of glaciers. As we know, glaciers are solid reservoirs in the snowy plateau and play an extremely important role in the plateau water cycle. There are many white snow mountains around Namco, which are actually glaciers. These glaciers are melting every year, supplying water to the downstream, supplementing the melting amount of glaciers through snowfall every winter, and finally forming a dynamic balance. However, with the intensification of global warming, this dynamic balance is broken, and the melting speed of glaciers is accelerated. The replenishment of glaciers through snowfall is far less than the melting amount. As a result, the glaciers kept retreating, and most of the water melted by the glaciers was injected into Namco Lake, which eventually led to an increase in the water level of the lake.

⑤ Besides, the water level of Namco is also affected by other factors.

⑥ The elevation around Namco is basically above 4,000 meters, which belongs to the alpine region, and a thick layer of frozen soil is formed on the surface under the action of perennial low temperature. Researchers from China Academy of Sciences have found that there is even a thick layer of ice in the frozen soil, which has become a part of the plateau water cycle to some extent.

⑦ These frozen soils exist in the form of ice for a long time at low temperature. After the temperature rises, especially in winter, the frozen soil begins to melt. These melted water will also be injected into the low-lying Namco Lake, causing the water level of the lake to rise.

Under normal circumstances, global warming will lead to an increase in water evaporation. However, research shows that evaporation is a meteorological factor influenced by many factors. With the increase of temperature, the evaporation of water does not necessarily increase, but is also closely related to cloud cover, sunshine, radiation and other factors.

The author once talked with Kang Shichang, a researcher and doctoral supervisor of Chinese Academy of Sciences, about the evaporation of Namco Lake. According to their analysis and research, in the year when the water level rises, the cloud cover, especially the low cloud cover, increases in Namco area, but the evaporation in Namco area decreases compared with before.

Attending this means that the decrease of evaporation is also a reason for the rise of Namco water level, but this factor is much weaker than the influence of glaciers and frozen soil on the water level of the lake.

? Having said that, everyone basically understands why the water level of the lake in Namco has risen. In the final analysis, this situation is caused by climate change. Therefore, it is of great significance to pay attention to the climate and the earth where we live.

Look, mung beans have answers.

Those mung bean things

According to research, as early as the Shang and Zhou Dynasties, our ancestors began to plant mung beans. In Qu Yuan's Lisao, there are records of mung beans. Mung beans, like soybeans, are native crops in China. Only compared with soybeans, mung beans always look humble. Soybean ranks among the five grains and is enshrined in the temple alongside rice, millet, millet and wheat, while mung beans can only be associated with sweet potatoes and live in miscellaneous grains. In fact, this difference is not difficult to understand. Because, in terms of nutritional components, mung bean is really too moderate, containing only starch (6 1%) and protein (22%). Soybean is rich in nutrition, and the protein content is as high as 40%, so there is? Meat growing in the ground? The reputation of.

(2) Mung bean is not as good as soybean except for protein content, and its starch content is not as good as rice, and its yield is even worse than wheat. Therefore, it is reasonable to divide miscellaneous grains.

Although it is a miscellaneous grain, mung bean is a supporting role that is unwilling to be lonely. There will always be mung beans in every kitchen, not to mention mung bean porridge, mung bean cake, mung bean popsicles for children and cold mung bean sprouts on our table. The mung bean soup of every household in summer alone is enough to prove its great contribution to the dining table.

④ More particularly, mung bean starch has excellent cooking performance. There is a special ingredient in China cooking? Vermicelli, (a kind of pure starch? Noodles? ), and in vermicelli, mung bean starch is better. The mung bean starch granules are surprisingly fine, which reduces the shearing force needed to make vermicelli. To put it bluntly, you can fully stir when making vermicelli. The vermicelli produced in this way will be bright and hard. So far, no crop can provide such high-quality starch, which is one of the reasons why fake mung bean fans are rampant.

In addition, mung beans rich in starch have a special purpose, which is to make frozen popsicles. The delicate starch of mung beans gives popsicles a unique sense of looseness. Of course, the popsicle frozen from this pure mung bean soup is far less soft than the mung bean ice cream later. However, in the summer when saccharin water popsicles ruled, mung bean popsicles were the best.

6. Just, can green mung beans really protect us from the scorching sun and provide us with coolness like its color?

In fact, mung bean soup as a summer drink is not because it has the magic to take away heat. But because it is rich in potassium, sodium, calcium and other minerals. In summer, we sweat easily. At this time, we lost not only water, but also all kinds of precious minerals. Drinking mung bean soup at this time can quickly replenish body fluids and lost minerals to achieve the purpose of relieving summer heat. Therefore, when rescuing heatstroke patients, we should not give them pure water, which will only make the situation worse.

Therefore, mung beans rich in various minerals have become the best products in summer. In fact, drinking mung bean soup in summer is the same as adding salty drinks after strenuous exercise. At the same time, there are some special aromatic substances (such as coumarin) in mung beans, which will bring us a refreshing mood.

Pet-name ruby just call? Mung bean soup? But usually the mung bean soup we cook is red because the polyphenols contained in mung beans are oxidized to form red substances, and this oxidation is related to the concentration of metal ions in water and the contact with oxygen. Then, if we cook with pure water and stainless steel pressure cooker, will it be easier to get the ideal? Green? Bean soup. Of course, drink it in time, or it will turn red sooner or later if it is left in the air for a long time.

Attending the popularity of mung beans is largely related to it? Detoxification? About the halo. There is a legend that the reason why the Shenlong family was lucky when they tasted the herbs was because he brought mung beans. This? Mung beans cure all poisons? The story is obviously a legend, but there are many medical classics that record mung bean detoxification. For example, it is said in "Kaibao Materia Medica" that mung beans can be used? Reduce swelling, relieve qi, and detoxify by hot pressing? ; Compendium of Materia Medica says mung beans are ok? Xiejinshi, arsenic, vegetation, all kinds of poisons? It seems that mung bean is a panacea. However, this is not the case. If superstitious mung beans can detoxify, it is likely to delay treatment.

17. The following understanding and analysis of the content of the article are incorrect (4 points).

A. Mung beans are native crops in China. Although the status is not high, it has a long history.

B. Although the content of mung bean starch is not as good as that of rice, mung bean starch is fine and its quality is higher than that of rice starch.

C. In the early years, mung bean popsicles made of pure mung bean soup were very popular, although they didn't feel loose.

D. After heatstroke in summer, you can drink mineral-rich drinks in time, but you can't drink pure water immediately.

E. Mung beans contain polyphenols and are easy to oxidize, so all the mung bean soup we drink is red.
