How many cities in the country are short of water, and which areas in China are short of water?

North China and Northwest China are the most severely affected by water shortages. North China is densely populated, has a developed industrial economy, and has a huge demand for water resources, but the supply is seriously insufficient. The northwest region is far from the sea, is an inland area, with a large desert area, and due to the blockage of humid air by plateaus and other terrain, precipitation is scarce and there is a serious shortage of water.

The total amount of water resources in China is quite a lot, but the per capita share is very low, about 1 4 of the world's per capita water resources, and the regional distribution of water resources in China has a significant imbalance, which is manifested in more in the east and less in the west, and more in the south and less in the north.

1.There is a shortage of water in northern China.

North China has a temperate monsoon climate. Summers are hot and rainy, and winters are cold and dry. The average annual temperature is around 8°C-13°C.

The annual precipitation is around 400-1000mm. The Inner Mongolia Autonomous Region has less than 400mm of precipitation and is a semi-arid region.

In terms of physical geography, North China generally refers to the vast area of China north of the Qinling-Huaihe River line and south of the Great Wall; It is bordered by Northeast China and Inner Mongolia Autonomous Region in the north. It is roughly bounded by the contour line of 10 accumulated temperature of 3200 (3000 in the northwest section) and the contour line of the average temperature in January of -10 (-8 in the northwest section).

Lack of precipitation and arid climate are the main climatic characteristics of Northwest China. Due to its location in the hinterland of the Eurasian continent, Northwest China has scarce precipitation in most areas except for the south of the Qinling Mountains, and the annual precipitation is less than 500 mm in most areas, which is a continental arid and semi-arid climate and alpine climate.

Among them, the annual precipitation on the Loess Plateau is between 300-500 mm, the Qaidam Basin is below 200 mm, the Hexi Corridor is less than 100 mm, Dunhuang is only mm, Turpan is less than 20 mm, and Ruoqiang is millimeter, almost all year round without rain. Due to scarce precipitation, arid climate, and widespread deserts, the surface water volume in Northwest China is about 220 billion cubic meters per year, accounting for only about 8% of the country's total runoff.

2.Water is scarce in the Northwest.

Northwest China is deep inland, far from the sea, coupled with the high plateau and mountain terrain to block the humid airflow, resulting in scarce precipitation and arid climate in this region, forming a vast desert and Gobi beach landscape.

Only a few areas in the southeast of the western region have a temperate monsoon climate, and most of the other areas have a temperate continental climate and an alpine climate, with severe and dry winters, high temperatures and scarce precipitation in summer.

Topography: The terrain of the western region includes the Tianshan Mountains, the Altyn Mountains, the Qilian Mountains, the Kunlun Mountains, the Altai Mountains, the Hexi Corridor, the Junggar Basin, the Tarim Basin, the Taklamakan Desert, the Turpan Basin and other mountains, basins, deserts and the Gobi.

Xinjiang, Gansu, Shanxi, Shaanxi, Ningxia, Hebei, Beijing, Tianjin, Tangshan.

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.

There is a shortage of water in the whole country! There are many Chinese! However, in comparison, North China (Shandong, Hebei, Henan, Beijing, Tianjin, Shanxi, etc.), Northwest (Xinjiang, Inner Mongolia), and Southwest (Sichuan, Yunnan, Chongqing, Guizhou) are relatively short of water!

The ability is limited, I hope to give you some help! Thank you!

The distribution of water resources in China is as follows: more in the east and less in the west, more in the south and less in the north, and generally speaking, it decreases from the southeast to the northwest.

Therefore, from the perspective of natural conditions, the northwest region of China has a serious water shortage.

However, the sufficiency and shortage of water resources are also affected by consumption, and from this point of view, China's North China (especially the Haihe River Basin) has a serious water shortage. Because there is less precipitation here, especially in spring, evaporation is strong, but the rain belt has not yet arrived, forming a spring drought. Moreover, it is densely populated, developed in industry and agriculture, and consumes a large amount, coupled with serious waste and serious water pollution.

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.

Water is the source of life, people can last 7 days without eating, but if you don't drink water for three days, it will be over, many plants and crops need water to grow, and many enterprises also need water to continue to operate, human society can be said to be difficult to move without water, which leads to some water-scarce areas with sparse population and backward economic development level, although we sometimes see floods in our country, giving people the feeling that our country is rich in water. In fact, our country is a country with a shortage of fresh water, especially in some areas, where the water shortage is very serious.

A glance at the areas with the most severe water scarcity in our country:

The following ** is a good record of the distribution of water resources in China.

Judging from the above situation, most of the most water-scarce places in China are located in the western region, especially Xinjiang and Inner Mongolia, which are areas with serious water shortage.

Xinjiang has the largest desert area in our country, where the year-round rainfall is very low, and the lack of water is reasonable!

But many people may not expect that many places in Inner Mongolia are also short of water! The main reason for the lack of water in Inner Mongolia is the low amount of precipitation.

How to solve the problem of regional water scarcity?

In ancient times, people relied on the sky to eat, and what kind of weather and climate God gave you determined your future food!

However, in the development of human beings to the present, it is completely possible to change some realities that cannot be changed in the past through technology and manpower, such as the problem of water shortage! ：

The main solution to the problem of water shortage is to develop water conservancy.

1. Dig deep wells.

In the past, the technology could not be reached, and the deep place could not be dug, but now digging deep wells is one of the means to solve the difficulty of draft.

2. Water diversion project!

For example, our water conservancy projects such as the South-to-North Water Diversion Project are an important means to solve regional water shortages.

3. Other water conservancy projects, artificial rainfall, etc.

For example, the construction of reservoirs to store water, artificial rainfall means, etc., in fact, these methods are being used in our country, and they have also achieved good results!

About 13 million people in the arid western regions suffer from severe water shortages. Water scarcity has become the direct cause of poverty in most areas of Gansu and Ningxia.

The areas with serious water shortage in our country are:

1. Northwest China [Northwest five provinces: Xinjiang, Gansu, Shanxi, Shaanxi, Ningxia] 2, North China [Hebei, Beijing, Tianjin, Tang].

According to statistics, 400 of the country's 669 cities have insufficient water supply, and 110 are seriously 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.

On the whole, China is a relatively water-scarce country, and the overall water shortage is very short, and the water shortage in the northwest of our country is very serious, but it is more formed by some natural reasons, and many cities in the southeast coast of our country are indeed water shortage, which also has nothing to do with the natural climate, mainly because we are densely populated in the southeast, and the population density in the coastal areas is too large. Therefore, most of the cities on the southeast coast are now generally declining groundwater very much, such as the Baotu Spring in Jinan a few years ago, which can only show that our groundwater level has dropped really badly. In fact, China itself is a water-scarce country, the northwest region is mainly because of its arid and hot climate, perennial precipitation is relatively scarce, so the water source in the northwest region mainly comes from some lakes and some rivers, and the southeast coast, ah also has a little precipitation will be more, but the population density of the southeast coast is too large, well, plus China's rivers and lakes, now it is not relatively large, so it leads to many cities on the southeast coast, In fact, the groundwater itself is very exploited, and it is already in a state of water shortage. If we can see these people around us a lot of times, and the concept is very good, and no one can pay a little attention to it, then we can save a lot of water in a year.

In fact, China is a country with a general shortage of water, and the distribution of China's water resources is extremely uneven, as well as many northwest regions, because of the perennial arid climate, and then the precipitation is relatively scarce, and the water resources are relatively scarce, so most of the northwest areas are actually generally short of water. The northwest is mainly due to climatic reasons, but the population density in the northwest will be relatively small, so this pressure will not be great for a while, but in the long run, there is indeed a very serious water shortage crisis in northwest China. Uh, in fact, the amount of groundwater exploitation in many cities in the southeast coastal area of China has been very large, the groundwater level has dropped very much, if there are small partners living in those areas should have a feeling, if there are rural areas, there will be, with the wells dug more than ten years ago, the water level has dropped very much, and even some have dried up, which shows that the groundwater level has dropped very much, Jinan Baotou has stopped spraying in the past few years, which shows that although these cities say that the precipitation is not very little, but it, due to too much population, the amount of mining is too large, Therefore, the groundwater is declining every year.

But from this point of view, China is actually generally short of water, I remember that at that time I seemed to have learned that the average water of Chinese seems to be less than 1 4 of the average, anyway, I think I personally think we should develop a good habit of saving water, only in this way can our water resources be effectively protected. The first very good habit.

The most water-scarce place in China must be Wuwei City, Gansu Province, where the water shortage is beyond ordinary people's imagination. The reality that people here only take a bath three times in their lives is definitely not hearsay, they are born, married, and when they die. In order to ensure the production of local non-ferrous metallurgical enterprises, even the upstream farmers of Jinchang City were forced to let the crops in the fields dry, not to mention the Minqin in the downstream, which eventually led to Minqin County becoming the most water-scarce area in China, and further evolved into the largest wind and dust storm center and origin area in northern China.

Although the concept of water scarcity is still vague in the central and eastern parts of China, as a member of the motherland, we have a responsibility to protect our own scarce water resources. Of course, cherishing water resources should not be just a "pledge" in our words. We should start with small bits, such as brushing our teeth every morning and turning off the faucet in time; At noon, the water used to wash the rice is also conducive to cleaning the pesticides on the vegetables; Intermittent showers when taking a shower at night, turning off the water when scrubbing, etc.

Again: don't let the last drop of water on earth become a human tear!

North China The Huang-Huai-Hai Plain is the largest plain in China, accounting for 15 percent of the country's area, 1 3 percent of the country's population and GDP, and 40 percent of the country's agricultural output. Industrial and agricultural production in the region is crucial to the country's sustainable economic development and food security.

Since the 80s, the climate in North China has been continuously arid, and the water shortage situation has become increasingly serious. From 1980 to 1989, the average precipitation in the Beijing-Tianjin-Hebei region and the Shandong Peninsula in 10 years was 10 to 15 degrees lower than the average for many years, and the temperature was 0 1 to 0 6 degrees Celsius higher. Due to the low precipitation and high temperature, the ground evaporation loss increases. At the same time, due to the impact of human activities, the amount of water supply has been significantly reduced.

According to the preliminary analysis of the Haihe River Management Committee, the surface runoff produced by the Hailuan River basin from 1980 to 1989 was only 15.4 billion cubic meters, which was 46.5 different from the average annual runoff of 28.8 billion cubic meters from 1956 to 1979, or about 13.4 billion cubic meters.

Which province is the most serious water shortage in China? To be clear, water scarcity refers to the amount of water resources per capita, some would say Xinjiang Province, some would say Gansu Province. In fact, these are not right, the most water-scarce place in China is the North China Plain, and the most water-scarce place in the North China Plain belongs to Hebei Province, as well as Beijing and Tianjin City, which are surrounded by Hebei Province, that is, the Beijing-Tianjin-Hebei region.

So why is the Beijing-Tianjin-Hebei region the most scarce in water, and why?

In 2019, the total area of the Beijing-Tianjin-Hebei region was 10,000 square kilometers, accounting for the total area of the country, with a population of 112.05 million, accounting for about 8% of the country's population, and a GDP of one trillion yuan, accounting for the country's gross domestic product. The above series of figures shows that the population has increased several times compared with the last century, and the total economic GDP has doubled several times, and the only thing that has not changed is the land area of the Beijing-Tianjin-Hebei region. The population is booming and needs water for domestic use; Industry is developing rapidly and requires industrial water; Crops grow on farmland and require water for agriculture; In addition, animal husbandry, animal husbandry, etc. need to be used in large quantities.

So where does the water come from?
