Water shortages in China's major cities into the ills of the <a href="http://www.ajaxify.info/"> Desk Help Software Tracking </ a> the first water use near the limit at 11:17 on November 2, 2010 China News Net .I want to comment (0) Font Size: T | T <wbr> Tencent microblogging broadcast to the utilization of water resources near-polar <a href="http://www.cachyeu.info/"> Help Desk Tracking Software </ a> limit ."/> <wbr>" are used more than ten years, and how to say no water no water out? ."Wang complained. Originally, Wang Huilongguan Tianxin home district where the waterworks and own wells the water level dropped, causing pump failure, not water, five thousand households so far have been for 5 months of life depend on water tankers. .call privatial well as residents protested, calling connected to municipal water, the water supply for a stalemate. Yuehua Jian, Wang bought a bottle of mineral water in the canteen and drank less than half thrown into the trash, the reporter was surprised ."There are half a bottle of water it, you do not you? ."Wang smiled disapprovingly," all right, to the office have drinking fountains, and put my purse, carrying, heavy and unsightly. .I do not believe such a big city but also the capital of no water use, such as 'South' and consequently do not have a start to worry about! ."With the" South ", we can really sit back and relax, humming a minor child to continue our indifference extensive use of water it? Then we call the mouth of" sustainable development ", how should the hands of radical .big cities, "poor water" chronic illness? "there is a demand there is supply can not be met, especially the water! ."Yin Ming Wan said," Water Diversion Project can do for a long time in the future alleviate the Beijing water problems, will not trouble 'water shortage', but not once and for all. .Without long-term water demand-side planning and management of water is not allowed to be unrestricted, endless growth continues, one day, 'water scarcity' will appear, will be restricting urban expansion and the main social and economic development .One of the obstacles. ."Status quo falling water tables," in fact is not only one of the waterworks and own wells Tiantongyuan water level dropped, according to the Urban Water Authority's statistics, average precipitation last year, Beijing is only 448mm, for the dry years, the middle of October this year, only 509mm, .lower than Beijing for many years the average annual precipitation of about 585mm, a large number of storing and using a lot of exploitation of groundwater and surface water, making groundwater recharge and water storage decreasing, the water table will continue to decline. ."Yin Ming universal reporters that the city waterworks and own wells draw groundwater is mainly to meet through a number of districts, the needs of enterprises and other collective units. In addition, due to environmental pollution can make the section of the underground water was also affected," underground wells like .Like a funnel, will focus on the flow of groundwater around the center of the lowest, if sustained over-exploitation, the water table will decline more and more, and finally may lead to land subsidence. ."Speaking of water resources development and utilization of nearly limit water use efficiency is often debate the issue, Yin Ming Wan said, Beijing has in recent years have greatly changed, from the water structure, between 2000 to 2009, there was a clear change .had the largest proportion of irrigation water from the city's total water consumption accounts for 40.8% to 33.8%; industrial water has become 26% from 14.6%, water consumption per million GDP, down from 111 m3 to 19 .cubic meters, down 82.7%; and urban water the opposite tack, from 33.1% to 41.4%! "current utilization of water resources development has reached 92%, if the amount of transfer water supply is taken into account, .it reached 93.87%, the limit can be almost used, the local and then there is not much potential to be dug. ."Population growth and urban expansion has increased the gap of Beijing water supply shortage of local resources is an indisputable fact, however," continuous, massive population growth and urban sprawl also leads to the huge growth in water demand, increased .gap. ."According to Municipal Water Affairs Bureau of Statistics data show that the total water resources in Beijing last year, 21.84 billion cubic meters, an average of 3.739 billion cubic meters for many years less 42%, water consumption has reached 35.5 billion cubic meters, up 040 million in 2008 .cubic meters. population how much water can it? Yin Ming million to reporters out of a set of data, the average annual growth rate of Beijing's permanent population was 2.58%, while the net input rate of population growth was 2.24%, that is, the population growth .86.77% are net importers of the population. 80 cubic meters per capita annual water demand of life per year will need to light a net importer of population growth of 35.34 million cubic meters of water (the end of 2009 the city's resident population reached a total of 19.72 million), while .Beijing itself is still in the average annual water shortfall over 12 billion cubic meters of embarrassing situation. as to improve the urban ecological environment, water, landscape water quality, the demand is also increasing, and last year accounted for 10.1% of the city's total water consumption. .However, many urban areas, lakes, canals are often not the people "treat" all kinds of garbage floating on top, seriously affecting the water quality, groundwater resources have been destroyed, water, natural ecological imbalance. urban water "recipe" .the construction of the water system, the collection of water ladder "system without the constraints of water, but expect people to consciously, then many people would from their own comfort, convenience to consider the phenomenon of waste water will be difficult to control. ."Yin Ming Wan said, because Beijing is the early construction of tall buildings, so most of the water system is not built, if the companies are now additional, high cost, so very few companies will take the initiative to build." If there is .appropriate policy could be improved. ."In addition, because Beijing is China's political and cultural center, large and small gathered by government agencies, non-residents pay household water because it is public, so the phenomenon is more serious waste of water." Taking into account the water Tedian such units .install water-saving devices is necessary for the waves <a href="http://www.sense-of-wonder.info/"> wells fargo home equity loans </ a> charges the water units and individuals to give some .sanctions can not be a mere formality. ."Strict water quotas for the residents there may be some difficulties, but may be charged as the bus fare ladder, like ordinary citizens and enterprises to the collection of water ladder. Relocation or closure of some large-scale water enterprises" in order to .Let the water do not become the bottleneck of urban development is the key to the implementation of industrial restructuring. ."Yin Ming Wan said, Beijing is a fixed water business for years, has achieved some results," but in the long run, also some large-scale water companies need to be part of the relocation or closure of the relocation of Shougang is a good .model. ."It is understood that the domestic steel industry, Shougang, as the leader of the annual water consumption in Beijing up to 5,000 million cubic meters, while the relocation of Shougang, Hebei steel industry after the intervention, although the new Shougang about 40 million cubic meters water annually, .However, these water primarily through the full use of sewage treatment plants discharge a large number of water every day, and in the local design of a desalination project, desalination of seawater each year 30 million cubic meters. this calculation, the relocation of Shougang Beijing and Hebei will .eastern water more than 100 million cubic meters per year. Note throttling, better to move closer to the sustainable use of water, according to the Office of the State Council issued the news that the South, South East, Middle Phase 155 Project design unit ., the basic completion of 33, accounting for 21%; in the construction of 67, accounting for 43%. Yin Ming Wan said the water diversion project is expected to be completed in 2014, before the water supply in the South, Beijing Water Resources Council .getting tighter, so cutting short-term special attention, especially in the urban residents and growing body of water into the case. "transit should be strengthened upstream water management, reduce pollution, keep the water source. .Similarly, Beijing should make the local environmental protection of water in transit, so that the downstream can then use. ."Yin Ming Wan said, the only way to better move closer to the sustainable use of water. Have written Notes from the city" big ", resources may not be" wide "as demand for water like a balloon, the more bigger and bigger, but how much can blow balloon in the end finally .see the pressure on the balloon material itself, has nothing to do with our subjective wishes. "big" cities may have a lot of resources to be called rich, cultural, artistic, economic, etc., but the natural resources not the case. There have been so described .Beijing's water situation, "If there is a bottle of water all over the world, then a glass of water left in China, while Beijing only one saliva. ."When the mass of the population to the cities, make the city more and more" big "when the reason that, even the saliva of a person can no longer be the exclusive.
