Our water resources are okay, right? What is the current state of water resources in China?

It can be said that it is quite scarce, and China is one of the 13 water-scarce countries.

China has a large population base, and water resources are scarce in some areas.

Think of the people in the Northwest.

China is currently one of the countries in the world with a serious shortage of freshwater resources, and the per capita water resources are insufficient. More than 400 of the country's more than 600 cities have a shortage of water supply, especially in the northern region. Due to the influence of the monsoon climate in China, the temporal and spatial distribution of water resources is uneven, and drought and flood disasters occur frequently, which is often prone to the phenomenon of flooding in the south and drought in the north.

In addition, human beings use water resources irrationally, and water resources are seriously polluted and wasted. In recent years, due to the continuous occurrence of deforestation and indiscriminate deforestation, soil erosion has intensified, rivers have been cut off in some areas, and the water area of lakes has shrunk, resulting in a serious shortage of water resources in some areas of China and difficulties in drinking water for people and livestock.

Suggestions: 1. Save: 1. Moderately improve the water standards of households and enterprises; 2. Advocate water-saving technologies such as sprinkler irrigation and drip irrigation; 3. Water resource recycling; 4. Expand the coverage of green vegetation and conserve water sources; 5. Expand the publicity of water conservation.

2. Governance: 1. Increase sewage treatment efforts and improve sewage discharge standards; 2. Actively research and develop seawater desalination technology to reduce desalination costs; 3. Build reservoirs and reservoirs to transfer water across river basins.

Our country is a country with severe drought and water shortages.

China's total freshwater resources are 2.8 trillion cubic meters, accounting for 6% of the world's water resources, second only to Brazil, Russia and Canada, ranking fourth in the world. However, because China is a large country with a large population, China's per capita water resources are only 2,300 cubic meters, which is only 1 4 of the world average, and it is one of the poorest countries in the world in terms of per capita water resources. However, China is the world's largest water consumer.

China's annual freshwater withdrawals account for about 13% of the world's annual withdrawals.

China has been suffering from water shortages since the 70s of the 20th century, and this is not alarmist, but an objective fact. Since the 80s, China's water shortage has gradually spread from local areas to the whole country, and the situation has become more and more serious, which has had a serious impact on agriculture and the national economy. The main existential situations are:

There is a shortage of resources in the north, a water shortage in the south, and an engineering water shortage in the central and western regions.

According to statistics, China's total water shortage is estimated at 40 billion cubic meters, and the annual drought-affected area is 2 million 2.6 million square kilometers, affecting grain output by 15 billion 20 billion kilograms, affecting industrial output value of more than 200 billion yuan, and 70 million people in the country still have difficulty drinking water. Water scarcity has a serious impact on the environment and people's physical and mental health.

Coping strategies: 1. Industrial structure adjustment: shut down those enterprises that consume a lot of water, pollute heavily and have a high cost of pollution control.

It is necessary to develop and implement cleaner production processes, realize the closed-circuit circulation of water or improve the treatment effect and reuse rate of wastewater, and also adjust the agricultural structure with good water, especially in arid and semi-arid areas, reduce the area of rice planting, and take the road of water-saving agriculture and sustainable development.

2. Large and medium-sized cities and towns should borrow urban domestic sewage treatment plants to improve the urban sewage treatment rate and reuse rate.

3. Control agricultural non-point source pollution, agricultural non-point source pollution includes rural life sources, agricultural non-point sources, livestock and poultry breeding, aquaculture and other pollution, to solve the non-point source pollution is more difficult than industrial pollution and domestic sewage in large and medium-sized cities, and it is necessary to control it through comprehensive prevention and control and ecological agriculture demonstration projects.

4. Develop new water sources: China's industrial, agricultural and domestic water conservation potential is not small, we need to do a good job in water conservation, reduce waste, and reduce water consumption per unit of GDP, and the implementation of the South-to-North Water Diversion Project plays an important role in alleviating the serious water shortage in Shandong and North China.

5. Strengthen the unified management of water resources, allocate and use market mechanisms and economic leverage, promote the conservation of water resources, and promote the management of sewage and its resource <>

China is a country with a severe shortage of water resources, which is only 1.4 per capita in the world. In general, the distribution of water resources is more in the south than in the north, and more in the east than in the west.

China is a country with a severe shortage of water resources, which is only 1.4 per capita in the world. In general, the distribution of water resources is more in the south than in the north, and more in the east than in the west.

Among the 669 cities in the country, 400 have insufficient water supply, and 110 have serious water shortages, most of which are in the semi-arid and arid areas of northern and northwest China, among which the shortage of water resources in North China has become an important obstacle restricting the development of the national economy.

There is a significant spatial and temporal imbalance in the distribution of water resources in China, and there is a significant uneven distribution of water resources in the north and south. 81% of the country's water resources are concentrated in the Yangtze River and its southern regions, while the Huai River and its northern areas account for only 19% of the country's water resources.

China's total freshwater resources are less than 2.8 trillion cubic meters, accounting for 6% of the world's water resources (compared to more than 18% of the world's population by Chinese), ranking fourth in the world after Brazil, Russia and Canada. However, China's per capita water resources are only 2,300 cubic meters, which is only 1 4 of the world average, and it is one of the poorest countries in the world in terms of per capita water resources.

However, China is the largest water consumer in the world. In 2002 alone, the country's freshwater withdrawals reached 549.7 billion cubic meters, accounting for about 13% of the world's annual withdrawals, which was about twice the 470 billion cubic meters of freshwater in the United States in 1995.

Currently, the world's freshwater resources account for only 2 percent of its total water5 per cent, of which more than 70 per cent is frozen in the ice caps of the Antarctic and Arctic, and 86 per cent of freshwater resources are unusable with the addition of inaccessible mountain glaciers and permafrost snow.

The freshwater resources that humans can really use are a fraction of rivers, lakes and groundwater, which account for only the total amount of water on the planet. Currently, 16 people in the world, some 1 billion people, are water-defined. Experts estimate that by 2025, more than 2.5 billion people in the world will suffer from water scarcity.
