China's agricultural development of water-saving In order to improve the efficiency of agricultural water， 50 to 60 years of research on water-saving irrigation techniques， the early 1970s focused on the gravity irrigation area of soil impervious lining channels; began in the mid-1970s， testing the promotion sprinkling irrigation， drip irrigation and other water-saving irrigation techniques; 80 In the mechanical and electrical pumping station and the implementation of water-saving irrigation area Well energy-saving technological transformation; in the 1980s to the early 1990s， well irrigation district in the north to promote low-pressure pipe technology from the 1990s onwards， the progressive realization of engineering technology， agricultural technology and management techniques Organic Water-saving industrial and urban water conservation work began in the late 1970s in the early With some cities of north China and areas of tension in the situation of water supply， water conservation as an effective mitigation measures received wide attention and From central to local， have established a basic water-saving， water-saving publicity carried out to develop a number of water-saving regulations， the entire water-saving work with a solid foundation， has made certain achievements， 10，000 yuan GDP water consumption has 1980 from the 1999 dropped to 9，820 cubic meters of 680 cubic Water-saving aspects of life， the vast majority of cities and towns are basically a measure to install water meters charges， cancellation of the basic package for residents living water system， a number of major cities such as Beijing， Tianjin， also introduced a number of strict Fixed management measures， a planned water， the super-increase plan to reduce waste and improve efficiency of water In the industrial water-saving， the current utilization of the water recycle common than in the early 1980s increased nearly 40 percent; terms in 1983 as the base， the general industrial use only by improving utilization of a repeat basis， the mid-1997 on the amount of water-saving 7 billion cubic meters; industrial sewage water to reduce emissions significantly， in 1998 the total industrial sewage and above county level in 1995 less than 5 billion cubic meters， and industrial waste water emissions from 1995 decreased by 1 billion cubic meters， compared 1990 decreased 8 billion cubic meters in 1999 the use of seawater in coastal cities of 7 billion cubic In water-saving agriculture， through the country in recent years in building water-saving production 300 key counties， 209 high standards of water-saving efficiency demonstration zones and 99 large irrigation areas and 40 medium-sized irrigation areas to carry out water-saving irrigation as the center The Rehabilitation and upgrading and building a number of state-level water-saving demonstration area; the end of 1999， the national water-saving irrigation area of 60 million mu， which spray， drip irrigation and micro-spray irrigation area of 3，400 hectares， irrigated area in pipe 8600 million mu， channels impervious area of 4 million mu addition， to promote water-saving irrigation and water ride， and other types of non-engineering area of 24 million mu of water-saving; water compared with 1980， water consumption dropped because Mujun， and New Year water 9 billion cubic Industrial development in water-saving， water-saving equipment， for a development， production， sales， marketing， service from scratch， from small to large scale is gradually taking shape， has become China's emerging In particular， last year the State Council held city water supply and water pollution control meeting， the countries have issued several important water-saving policies: the State Council on strengthening the urban water supply water-saving and water pollution prevention and control of the notification (of the (((□ 2000] 36); Ministry of Water Resources， State Economic and Trade Commission， and other six ministries on the issue of strengthening of industrial water-saving work of the views of the State Development Planning Commission introduced the reform of water prices to promote water-saving guidance， for the development of water-saving lay the
the water in our life is important it can help us do things，such as wash dishes，so we should save water we can We can wash water used to flush the toilet， washing water is used to water
