● per capita share of water resources is very limited According to the World Bank in 1998 on the 132 national statistics, China's total water resources of the world's first four, but the per-capita share of water resources is ranked 82. According to international standards, the per capita water resources of 2,000 cubic meters is a serious water shortage brink of 1,000 cubic meters per capita minimum requirements for the survival of mankind. At present, China's 15 provinces, autonomous regions and municipalities serious than the per capita water resources dry line, seven provinces and regions (Ningxia, Hebei, Shandong, Henan, Shanxi, Liaoning, Jiangsu) per capita quantity of water below the minimum survival requirements.

● extent of water pollution, according to the Ministry of Water Resources on the tremendous loss of the more than 700 rivers around 100,000 km long river's water quality assessment, 46.5 percent of the river pollution; 10.6% of the serious pollution of the river, water Benji lose value . More than 90 percent of urban water pollution has been serious. In all seven major river basin, Taihu Lake, the Huaihe River, the Yellow River Basin have more than 70 percent of river pollution; Haihe, Liaohe Basin-also very serious pollution, pollution of the river more than 60 per cent, there are 1 / 4 of the population drink does not meet the health standards of water. Water Pollution a direct impact on the life of the people in our country, the survival environment.

● shrinking lakes and rivers, the Yellow River drying up in the Yellow River from 1972 to the beginning of 1998 there disconnection of the 27 years, the Yellow River Lijin station stop in a total of 21, reached four years of stop-off frequency, for a total disconnection 1,050 days, the average Each year 50 days disconnection, 1997 devascularization 226 days, up to 704 km river drying up of the lower reaches of the chief of 90%. Haihe River valley in the middle and lower reaches of the river basic dry, estuaries increased siltation, ecological damage to the environment seriously. Since the drastic reduction of runoff, and the discharge of sewage towns are not diluted. A lot of sewage River, the image was called: "Without the river do not do it, then there is water pollution." Survey shows that nearly 30 years ago, the lake surface in China area has been reduced by 30 per cent.

● Northwest Region Water Environment bad At present, China's northwest arid, semi-arid region lakes He was a very serious problem, and some lakes salinity and salinity increased significantly, especially the northwestern lakes of a trend more obvious. Bosten Lake in Xinjiang, due to the construction of irrigation projects upstream, causing a sharp decline in the water, high salinity of the irrigated area continued to retreat into the lake water, therefore, in the lake within a short span of 10 years from fresh water into the lagoon, increased salinity of the water six times, and surface-to reduce 120 square kilometers, 3.54 meters lower the water level. Known as the "green labyrinth" of the Junggar Basin west of the Ebinur Lake, in the 1960s, the Great Lakes region due to deforestation for development, the closure of 70 water, the lake has Ebinur Lake has been the past 600 square kilometers to 1,300 square kilometers, dry The lake has been reduced salt desert. China has the largest in the history of the lagoon - Lop Nur has also dried up.

● shrinking wetland area, and ecological degradation as a result of population growth, expansion of cultivated land, trespassing types of ecological change, China's shrinking wetland area seriously. Reclamation to the Great Northern Wilderness years of this country's largest wetland area reduced by 60 per cent, the Sanjiang Plain wetlands area has been the founding of the initial 4.43 million hectares dropped to 1.9 million hectares. Failure to take urgent measures to protect more than 10 years Sanjiang Plain wetlands will be lost.

● South Weihucaotian Weihucaotian serious consequences in the South Lakes area is the primary reason for the decline. Have an awe-inspiring group of Jianghan Lake lakes disappear because of reclamation and 983 area reduced 2,041 square kilometers, only 83 lakes, Dongting, a mighty 800 in less than 40 years time, the reclamation area of 2.26 million mu, siltation and reclamation casual, resulting in ecological vicious cycle of the Great Lakes region.

● excessive drilling of groundwater, surface caused environmental problems due to scarcity of water resources and worsening water pollution, which in some areas of groundwater predatory exploitation, excessive extraction of underground water is very serious. According to incomplete statistics, China has formed underground waters of the 149 landing funnel, the funnel area of 158,000 square kilometers, of which serious drilling area of 67,000 square kilometers, accounting for 42.3% of the drilling area. 's Average 6.78 billion cubic meters of underground water drilling, and some funnel water depth Centre has 60 - 80 meters, in some cities, surface subsidence, causing serious consequences.

● erosion of a wide range of industries, the consequences of those in gifted the world's soil erosion has become one of the worst, the area of soil erosion of 3.67 million square kilometers, accounting for 38 per cent of land area, water erosion area of 1.79 million square kilometers . In addition, the annual loss of more than 50 million tons of soil, the soil erosion in each of the additional area of 2,100 square kilometers of desertification, loss for the same reasons the area of arable land over 70,000 hectares. A year away soil erosion in Loess Plateau of nitrogen, phosphorus and potassium reached 40 million tons, the equivalent of one year's production of chemical fertilizers. Win water pollution and frequent accidents. In recent years, water pollution incidents in various parts of the country have occurred frequently, and in 1600 the average annual starting over. 1994 Huaihe serious pollution accidents, resulting in Jiangsu and Anhui provinces 1.5 million people had drinking water problems. After the Spring Festival in 1996, the Huaihe River pollution accidents from happening again, Bengbu City 700,000 people to water scarcity. Over the past 10 years, the Haihe River Basin alone amounted to hundreds of water pollution accident, caused by water pollution regional disputes have occurred frequently, seriously affecting social stability.


Earth's water reservoir is very rich, a total of as much as 1.45 billion cubic kilometres. Earth's water, even though a huge number, and being able to direct the production and use of living, but pathetic. First, the water is salty and bitter, not drinking, not pouring, also difficult for the industry. Secondly, the Earth's freshwater resources are only 2.5% of the total volume of water, in this small freshwater resources, more than 70 percent have been frozen in the Antarctic and Arctic ice, add to the use of mountain glaciers and Wing frozen snow, 87% of the fresh water resources difficult to use. Human beings really able to take advantage of fresh water resources in rivers, lakes and groundwater part of the Earth's total volume of about 0.26%. Global freshwater resources are not only scarce and extremely uneven geographical distribution. By geographical distribution, Brazil, Russia, Canada, China, the United States, Indonesia, India, Colombia and the Congo nine of the country's freshwater resources of the world's freshwater resources 60%. About 40 per cent of the world's population of 80 countries and regions about 15 billion people lack water, which 26 countries and approximately 300 million people are extremely dry. Even more frightening is that, it is estimated that in 2025, the world will be 3 billion people will face water shortages, 40 countries and regions in a serious shortage of freshwater.
China's total water resources of 2.8 trillion cubic meters. Of which 2.7 trillion cubic meters of surface water and 0.83 trillion cubic meters of groundwater, surface water and groundwater due to conversion between each other and resupply, two double deduction of 0.73 trillion cubic meters, and the runoff is not about to repeat the groundwater resources 0.1 trillion cubic meters. In accordance with internationally recognized standards, and the per capita water resources of less than 3,000 cubic meters of dry mild; less than 2,000 cubic meters per capita water resources for moderately dry; less than 1,000 cubic meters per capita water resources for the serious water shortage; per capita water resources less than 500 cubic meters of water scarcity. China now has 16 provinces (autonomous regions and municipalities) per capita quantity of water (not including transit water) below the line of serious water shortage, six provinces, autonomous regions (Ningxia, Hebei, Shandong, Henan, Shanxi, Jiangsu) per capita water resources is less than 500 cubic meters. China's total water resources is not over, ranked first in the world in six, and the per capita share is less, 2,240 cubic meters, in the World Bank statistics 153 countries ranked in the first 88. Distribution of water resources in China is very uneven, and the area south of the Yangtze River Basin, the country's land area accounts for only 36.5% of its water resources accounts for 81% of the country; its north, the country's total land area of 63.5%, the quantity of water only 19 per cent of the country. This face severe water resources situation, we do what it is:
1, a water awareness Unfortunately, for a long time, people generally believe that water "inexhaustible," not knowing that I cherish, and some even water wasted. Should be aware that the per capita of water resources in China is not rich, not even geographical distribution, and interannual vary greatly, the year also unpredictable change, coupled with pollution, shortage of water resources, water supply even more hard-earned. I cherish the basis of water-saving water is only aware of "saving water glorious, and a shameful waste of water," can always pay attention to water everywhere.
2, cultivate good habits, According to an analysis, as long as the attention to the family to remove bad habits, we can save water around 70%. And waste a lot of water-related habits, such as: cigarette butts and broken toilets Chongdiao fine waste; access to a cup of hot water, cold water and many simply release them; first washing potatoes, carrots after peeling or washing after Optional vegetables; water when the gap between the (open to guests of the calls, change TV channels), not related faucet; water, forget customs faucet; wash face, brush teeth, let the water flow has been; sleep, go out before , do not check faucet; equipment leaks, not promptly repaired.
3, the use of water-saving appliances, in addition to the family of water-saving attention to develop good habits of water, adopt water-saving devices is very important, but also the most effective. To save money, many people would rather take its own course and would not replace the water-saving devices, in fact, long-term pay so much water down the more uneconomical. Use of water-saving appliances, save money, but also to protect the environment, not the double benefit? A wide range of water-saving devices, water-saving water tanks, water-saving leader, such as water-saving toilets. Several casually used on the water to make a lot of contributions ah!
4, slug flow leak check at home, "water dripping into the river" is not a joke. Frequently check water pipes in the home. Beginnings, we should not overlook the faucet and water leaks in the first section. Found leakage, we must promptly requested or repair their own hands, and plug the water. 1:00 repair leaks can simply switch temporarily by the flow or control. The good faucet, the water taps on the door fastening half leakage flow naturally small, the same amount of time, the loss of water is reduced by half.
On the production, in particular some high-consumption water industry, we should focus on how to optimize the operation of the water system, how to improve the concentration of the water cycle, how to improve the use of recycled water, such as water-saving as the focus of the work, and actively organize and technology research and improve the comprehensive utilization of water at the same time develop practical operating system, a fixed water consumption product management, and as a technical and economic indicators for assessing and reducing waste.
For a long time, most people have the concept of water saving, but the lack of concrete action, extravagantly used the phenomenon is still relatively common. Some people think that big业大, together with the Director of the upper riverside think that this source of inexhaustible, the lack of water-saving sense of urgency and sense of crisis. If true to the "high water than oil", we have to grasp the Huizhiwanxian water conservation work.

The way to save the global warming
SOS_ the SOS
        Today saw a news: the United States Space Administration (NASA) satellite photos that North and South polar ice melting is accelerating. Greenland ice on the surface than 15 years ago, less than 4 times its temperature is 17 to the highest. NASA Chief James climate scientists. Sen Han said: "We have been a turning point, but we have not yet beyond irreparable proportions. Can we reverse the overall situation, it must be immediately changed, action"
        As to the trend now, a north-south ice in 2012 will be completely melted!
       The source pointed out that: If the ice melts completely, sea temperature rises, and then from the ocean, natural gas will be released, we will Xidao for marine gas and poisoning, in a large number of marine natural gas, enough to kill everyone!
       Originally the North-South polar ice reflected sunlight into space, accelerated melting now, not reflected sunlight, and because ocean temperatures have been very high, further warming of the ocean north and south polar ice melting, melting the ice because ocean temperatures more , a vicious cycle. In accordance with the current rate of warming, if countries did not immediately resolved, four to five years time, the world will perish!
       This is really a very urgent! Dear friends, what we can do is appeal to people around immediately swing into action, from the start with ourselves, vegetarian, by adding environmental protection.
       As long as all our people and the government to take urgent measures to save the Earth also can we live in this beautiful planet. Http://www.youtube.com/watch?v=FJqO4HbolQk
