Water is found atmosteverywhere. Even in the driest part of the world there is some water in the air.
As we all have found out, water may be a solid, or a liquid or a gas.When it isa solid, it may be as hard as brick, When itis a liquid, you can pour it out of a container. When it is a gas, you cannot see or feel it.
Although about 70 percent of the earth's surface is covered with water, But with the rapid development of agriculture and industry, more and more water is needed. Therefore, water is becoming scarce in many places. What's more, a lot of rivers and lakes are beginning polluted by the waste watcr from factories. Fish can't live in them any longer. At the same time, thc waste water does great harm to people's health.

大家好，我是崔學榮，今天我要和大家談一談水的重要性。
水對生物很重要，沒有水，地球上就沒有生命。所有的動植物都需要水。人類也需要水。
水幾乎無處不在。即使在世界上最干燥的地方，空氣中也有水。
水，正如你所了解的，有固態(tài)、液態(tài)和氣態(tài)。當它是固態(tài)時，它可以像磚一樣硬;當它是液態(tài)時，你可以將它從容器中倒出;當它是氣態(tài)時，你看不見或感覺不到它。
雖然地球表面70%是水覆蓋著，但是隨著工農(nóng)業(yè)的迅速發(fā)展，水的需要量越來越大。因此，許多地方缺水。而且，許多河流湖泊被工廠排放的污水所污染，魚不能生存。同時，廢水給人們的健康帶來極大的危害。
為了保持河流湖泊清潔，防止水污染，我們必須采取措施，阻止各種污染。

From The first national water resources census bulletin，By the end of 2011,there are 45000 reasons basin area of 50 square kilometers above, total length of 1.5085 million km. There are 22900 reasons basin area of 100 square kilometers above. There are 2865 natural lakes water is greater than 1 square kilometers with a total area of 7.8 square kilometers. The country has about 98000 reservoirs, with a total capacity of 98000 cubic meters. The national total of 638900 lakes water inlet, the earth's surface and underground water source is respectively 1.17 and 1847.
China's per capita water resources is only 2100 cubic meters, only 28% of the world's per capita. In the northern region, water resource is very shortage, the Yellow River, huaihe river, haihe river three per capita water resources quantity respectively for the national average of only 30.1%, 21.6% and 12.9%.
China's per capita fresh water resources is only a quarter of the world's average, ranked 110 in the world, is one of the poorest countries in the world per capita water resources. Available water the presence of more than 400 cities in more than 600 cities has water supply shortage problem, the serious water shortage city more than 110, the national total water shortage of 6 billion cubic meters.
China's top ten river basin water quality success rate is 2/3, Local water quality is worrying，overall，
Through years of efforts, we have improved water quality in China, the top ten overall for watershed water quality mild pollution, but at local area, the water quality of local water environment pollution is still serious. Recently published in domestic academic journal "science bulletin", according to an
article. Surface water contains 68 kinds of antibiotics in China, and the concentration is higher. There are 90 kinds of the antibiotic pharmaceutical ingredients being checconcentration is much higher than abroad. 90% of our country urban groundwater by different level of organic and inorganic pollution of poisonous and harmful pollutants, 70% of the pollution of river water system, more than 90% of the river pollution flows through the city.On enhancing urban water supply water saving and water pollution prevention and control work Promulgated by the state council in 2000 point out that we should gradually change the past a drainage system, a single reservoir and a river water to the city water supply way, Take "library series more, drainage network, surface water and groundwater alignment, the optimized configuration of water resources".
By the end of 2013, the total 3895 key projects, medium and small rivers Management River is 35000 kilometers long. By 2015, the project management of small and medium-sized rivers around 5000, governance river is 60000 kilometers long, can make the 340 million population and 330 million mu of farmland protected by flood control.
In order to ensure the river health life, implementing strict water management system in our country, defined the development and utilization of water resources, water use efficiency, water function area restriction, they use "three line":1. Set the limits of the total water 2. The red line to promote water-saving efficiency of water use 3. The red lines limit, protect water quality,
Expert introduction, the current "three line" index system of water resources to cover 95% of the local administrative region and more than 50% of the county administrative region, which means that the water resources management in the future will be more strictly: Strict management and protection of groundwater, the groundwater water withdrawal amount control and water level control.
Strict control into the lakes pollution gross, the position is beyond the water function area limits of the total area, limit for examination and approval of new water and sewage outlet into the rivers.
I think the best way to curb water pollution is in legislation and law enforcement supervision. The water pollution problem has to be reckoned with, because it has two characteristics: The first: concealment, imperceptible. Second: once the pollution, it is difficult to treatment and recovery. In the driven of the interests, pale the role of the propaganda work, to really stop water pollution phenomenon only can depends on the guarantee of law and law enforcement supervision. Therefore, a specific law to protect drinking water sources is fundamental. Strengthen the regulation of drinking water sources protection law enforcement is the important guarantee. To continue increasoing the intensity of law enforcement inspection, investigate seriously illegal threat to drinking water quality environment act.
For urban water conservation, I put forward the following Suggestions：First, optimize the urban layout and industrial structure, Second, increase the level and efficiency of utilization of the urban internal water cycle. Third, to strengthen the construction of urban water supply. Fourth, strengthen
the protection of urban water supply.
I believe that as long as there is a reasonable means and strict supervision legislation and a determined, the problem of water pollution can be effectively improve!
