Water is the source of life, where is the most water scarce place in China?

In Dingxi, Gansu Province, precipitation is scarce and variable, the climate is dry, and meteorological disasters are frequent. The average annual temperature, frost-free period of 122 160 days, the average annual rainfall of 350 600 mm, Dingxi City is poor in water resources, the per capita annual occupancy is more than 600 cubic meters, the average annual occupancy per mu of cultivated land is 140 cubic meters, the north is extremely scarce, the water quality is poor, the mud content is large, the farmland is more, and the water required is large.

There are many cities in China that are short of water, such as Beijing, Tianjin, Shijiazhuang, etc. But the most water-scarce county is in Dingxi County, Gansu Province, which is also the poorest place in China. The annual rainfall is only about 250 mm, while the evaporation is as high as more than 2,500 mm.

To what extent is there a shortage of water? Bathing three times in a lifetime, birth, marriage and death, of course, this is not uncommon. Xihan has to open his mouth to drink some tears when he is crying.

Anyone who has been there will be deeply shaken by the heart.

Malta. According to statistics, there are currently 20 countries in the world that are water-scarce. Malta has the highest level of water scarcity among the most water-scarce countries, with an annual per capita water availability of only 82 cubic metres.

Based on the United Nations hypothesis for population**, Libya will be the top water-scarce country by 2050, having been the fourth-largest water-scarce country in 1995 with an annual per capita water availability of only 31 cubic metres. Malta, with its slower population growth, will then become the fourth most water-scarce country, with a per capita water availability of 68 cubic metres.

Water is an inorganic substance composed of hydrogen and oxygen, which is a colorless and odorless transparent liquid at room temperature and pressure. water, including natural water; Artificial water. Water is one of the most common high-destruction substances on the earth, an important resource for the survival of all life including human beings in Qiduanchong, and the most important component of living organisms.

Water has played an important role in the evolution of life.

If you want to lose weight, but don't drink enough water, your body fat can't be metabolized, and as a result, you gain weight. Proper drinking of water can avoid gastrointestinal disorders. You can drink some hydrogen-rich water half an hour after your meal to strengthen your body's digestive function and help you stay in shape.

Water is something that everyone's body cannot lack, in normal times, it is best to choose to drink boiled water, which can wash our body, dilute blood concentration, and help our body metabolize faster, and can also help us regulate body temperatureHelps relieve constipation

And drinking a glass of water before a meal can improve satiety, which has a good effect on friends who want to **, so that the intake of things is less than usual, helping to eliminate toxins and garbage, and for women, it is the best manager.

Water intake includes all waters, such as direct from drinking water and beverages; direct moisture from food; Metabolic water from the oxidation of food in the body to produce. Water can be excreted through the kidneys and digestive tract in the form of urine or feces, as well as through the exhaled air and evaporated water vapor from the lungs.

Drinking more hydrogen-rich water can keep the human body in good condition, reduce the probability of colds, thereby reducing the incidence of rhinitis, people suffering from rhinitis usually try to wash their faces with cold water, and rinse the nasal cavity, which can promote blood circulation in the nose.

The weather is relatively hot in summer, many people like to drink some cold drinks, especially in the hot summer, most people will choose frozen drinks like this, which can effectively reduce the temperature of our body and eat some cold food, in fact, this is very unfavorable to physical health, and is not conducive to relieving the heat, the most scientific and healthy is to drink warm water.

Water is not only an important component of the human body, but also an important component of food. Water from purified water is easily metabolized and excreted from the body, while water from food can prevent rapid loss of water from the body, which is beneficial to health. Therefore, about 30% of the daily water requirement is required for food in normal temperature weather.

In general, fruits and vegetables have a higher water content than other foods.

In the early stage of dehydration, there will be symptoms of dry mouth and thirst, if the severe lack of water will lead to dehydration, affect the function of the kidneys, the urine will become dark and yellow, and if it continues to worsen, there will be dizziness and palpitations, and at the same time affect brain power and memory, and auditory hallucinations will occur.

**It will become very yellow, especially dry, inelastic, and will also cause constipation, which can cause joint pain and damage to the body.

I think it can cause weakness in the limbs, hotheadedness, dizziness, loss of appetite, and lack of sleep.

Summary. The reuse rate of industrial water in China is about 60% to 65%, and in developed countries, it is generally more than 80% to 85%, and household water waste is also very large. A recent Xinhua survey also found that more than 15 percent of China's urban water supply networks are leaking.

Excluding the normal loss rate, if it can be reduced by 10 percentage points, it can save at least 5.2 billion cubic meters of water, which is equivalent to the water volume of more than 2,000 Kunming lakes in conservative calculations.

Is there a place in China where there is a severe water shortage?

Good morning, dear! I'm glad to be able to answer for you, typing takes a little time, please wait a minute, I'll give you a complete answer!

Hello dear, glad to answer for you. Dear, there is a serious shortage of water in Xinjiang.

China's water resources are scarce, with a per capita water resource of about 2,100 cubic meters, a quarter of the world average. According to international standards, less than 3,000 cubic meters of water resources per capita is considered mild, less than 2,000 cubic meters is considered moderate water shortage, less than 1,000 cubic meters is severely water shortage, and less than 500 cubic meters is extremely water shortage.

The reuse rate of industrial water in China is about 60% to 65%, and in developed countries, it is generally more than 80% to 85%, and household water waste is also very large. A recent Xinhua survey also found that more than 15 percent of China's urban water supply networks are leaking. Excluding the normal loss rate, if it can be reduced by 10 percentage points, it can save at least 5.2 billion cubic meters of water, which is equivalent to the water volume of more than 2,000 Kunming lakes in conservative calculations.

Seawater is not drinkable. Drought salt water is also not drinkable, and groundwater can only be a little bit, so there is no water.

One is Huining, Gansu - Huining, Gansu is probably the most water-scarce place in China.

Huining, Gansu Province, is probably the most water-scarce place in China, where people are said to bathe only three times in their lives, when they are born, married, and when they die. For a long time, the people there mainly live by storing rainwater, and every household has a water cellar, the previous water cellar only has a water output of 15 cubic meters, ** After the 121 project, the general water cellar has been expanded to 30 cubic meters. The so-called 121 project is to build a storage level for each house, which consists of a roof and a yard.

Generally, the roof is 60 square meters, and the yard is 40 square meters; Build two water cellars for each family; Next to each house there is a vegetable garden for itself. Nowadays, people there generally use water in this way, take the water out of the water cellar, wash the vegetables first, after washing it after many times of precipitation, filter out the sediment, leave the relative clean water, and then wash the face, hair, feet, and finally water the used water. When watering, special attention should be paid to the mode of "point watering", a scoop of water, less than three seedlings, more than four seedlings.

**Measures are being taken to further improve the water problem in the Hoeryeong area. The main method is to lift irrigation, and the water is adjusted up to a vertical height of several hundred meters through electricity. For such a project, people need to pay more than 3 yuan per cubic meter of water.

This is a very cheap **, because if you use a tractor to carry water to eat, the cost is about 50-100 yuan per cubic meter. The project is said to be completed in May 2007. At that time, the people here will be able to greatly alleviate the problem of water and even take a bath.

The people of Huining live in such difficult natural conditions, and the children here study very hard. It is said that since the liberation, 40,000 college students have been admitted to Huining, or 160,000 if you calculate the number of people in each household of four. And the population of this place seems to be only 210,000.

The second is the North China Plain, and the most water-scarce place in the North China Plain is Shijiazhuang. It's not that precipitation is scarce, it's that there is too much water.

The most water-scarce place in the world:

Middle east. Oil is abundant there, but due to its desert location, large population, and very scarce fresh water, fresh water is more precious than oil.

Five Trees Village is where there is only one drop of water a day for one tree.

Northwest China is the driest region in China, accounting for 44 percent of the country's land area, while the average annual water resources account for only 8 percent of the country's total, with less than 120 billion cubic meters of available water. In many places, the social and economic use of water has crowded out ecological water use, causing natural rivers and lakes to shrink or even disappear, and land desertification has expanded rapidly, resulting in a serious ecological crisis. According to the phased results of the ongoing national comprehensive water resources plan, the current water shortage in northwest China is about 5 billion cubic meters in a normal year.

In Ningxia, water scarcity is a serious problem. Zhao Tingjie, vice chairman of the Ningxia Hui Autonomous Region, said that since the 90s of the last century, the water from the Yellow River has continued to dry up, and in 1998 and 2004, Ningxia allocated an average of 3.05 billion cubic meters of allowable consumption of the Yellow River, of which only 2.49 billion cubic meters in 2003, and the contradiction between supply and demand was particularly prominent. At present, more than 2 million rural people in the region still have unsafe drinking water, including 550,000 people in the central arid zone.

In addition, the deterioration of the water ecological environment cannot be ignored. At present, the compliance rate of water function zoning is less than 35. The degradation of natural lake wetlands is serious, and the area of natural lake wetlands has decreased by about 60% compared with the middle of the last century.

The problem of overexploitation of deep groundwater in urban areas such as Yinchuan and Shizuishan is also serious.

According to the Ministry of Water Resources, 400 of the country's 669 cities have insufficient water supply, and 110 are severely short of water. Of the 32 megacities with a population of more than 1 million, 30 suffer from chronic water scarcity. Water quality is poor in 46 key cities, and 9 of the 14 open coastal cities are severely short of water. Beijing, Tianjin, Qingdao, Dalian and other cities are the most severely deficient.

Taking 1996 as an example, the national industrial wastewater discharge is 20.59 billion tons, and the discharge of domestic sewage is expected to be about 15 billion tons, due to the slow progress of sewage treatment, the standard discharge rate is not high, China's rivers, lakes and reservoirs are generally polluted to varying degrees, except for a few water system tributaries and some inland rivers, water pollution is generally aggravated, 78 in the urban river section is not suitable for drinking water sources, and 58 are below the five types of water quality; 50 percent of urban groundwater is polluted, lakes are generally polluted by total phosphorus, river water pollution leads to a large number of fish deaths, nitrogen and organic pollution, eutrophication, and ozone-depleting organic matter pollution are serious problems. 60% of southern cities are suffering from water shortages due to polluted water. The most memorable incident was the 1995-1996 incident in which millions of people in the Huaihe River basin had difficulty drinking water due to water pollution.

Water pollution further reduces the amount of available water resources.

North China is the most scarce because of the above-ground rivers in the lower reaches of the Yellow River, the long ice period of the rivers, and the excessive use of water for industrial and domestic use, which causes serious water pollution.

Needless to say, the Northwest is a place where water is scarce. Because precipitation is scarce, the desert is widespread.

The southwest was originally one of the most water-rich regions. And it is the most developed place in China for hydro energy. Because it is the birthplace of many rivers, it is located at the junction of the first and second steps, and the drop is very large. But now there is also a drought and a lack of water.

About 13 million people in the arid western regions suffer from severe water shortages. Water shortage has become the direct cause of poverty in most areas of Gansu and Ningxia, and it is the luxury of many mothers in those areas to let their children drink a sip of clean water and take a bath.

The areas with serious water shortage in our country are:

Northwest China, five northwest provinces: Xinjiang, Gansu, Shanxi, Shaanxi, Ningxia;

North China: Hebei, Beijing, Tianjin, Tang.

There is a shortage of water in many places. It is most severe in the north and north-west.

In the dry western region, with a population of about 13 million, there is severe water shortage.

Sichuan Province has the most abundant water resources in Sanzhou.

Yunnan lacks water, such as Qujing, Zhaotong, Wenshan and so on.

Tianjin, Beijing, Gansu, Ningxia and other 7 cities.

It's fun, ha, I'm very skeptical, the literary committee asked my brother, and I also drank it overnight, just now I asked Ha and uh, and my brother Ye crossed the river u ghee lamp and hungry oh oh dormitory.
