Qingdao Urban Development And The Contradiction Between Water Supply And Solutions

Qingdao is not only important coastal port city in China, but also a serious water shortage in northern China cities, the city’s total water resources for many years the average2.21billion m3, per capita water resources313m3, only12%of the national average, are urban water resource. In addition to resource shortage, the increasing degree of water pollution in recent years and the lack of water conservancy projects exist also caused the water quality of Qingdao, and engineering of the water shortage problem.With adjustment of industrial structure and division of the continuous improvement of urban functions, Qingdao City economy in a sustained and rapid long-term development stage, but the shortage of water resources to the Development of the constraints of social economic development along with an increasingly prominent problem. Analysis of water supply and demand situation in Qingdao over the years, combined with the "Qingdao City Master Plan" and "integrated water resources planning in Qingdao," on the forecast of urban development in future years, expected the city of Qingdao on water demand in2015was3.399million m32020Qingdao, the city’s water requirement is4.486million at m3.Capacity of urban water supply at the current estimated daily water supply in2015, Qingdao will reach70million gap in m3, and by2020the daily water supply gap of Qingdao will reach1.09million m3, which would seriously affect agricultural production in Qingdao, the city’s normal population life and sustainable economic and social development, but also a potential threat to social stability.The unique geographical location, Qingdao, and climate characteristics make the water shortage problem in Qingdao, the coastal cities in the country is more representative. Because, from the national point of view, not only in the coastal city of Qingdao, location, in the country’s maritime climate with typical features of coastal areas, and according to the center of the theory generally located in Beijing, Qingdao and Shanghai, the two largest cities the middle, in function and size is second only to the two sub-cities; Secondly, from the City Group of the scale, basically at the center of Qingdao City, from the province of view, Qingdao City, Shandong, outreach is the biggest portal, so if you can solve the problem of water shortage in Qingdao City, Qingdao City, then the country was close to other cities can learn from the coastal city of Qingdao, the practice of other coastal areas of experience to solve water shortage problems.Innovation of the paper is there is going to face in Qingdao City, the situation of water supply shortfall, through comprehensive investigation and statistics over the years, Qingdao, agriculture, urban living, industry, construction industry, tertiary industry, and ecology of water supply and demand of various industries, analysis water out of the industry growth rate over the years, combined with the overall urban planning in Qingdao on the future level of economic development and the annual population growth projections, is expected to Qingdao in2015and2020, water demand in various industries, and in accordance with the existing water supply Qingdao capacity and water resources development potential, the future level of Qingdao City’s water supply and demand balance in the analysis, to find out the supply gap. and finally the actual situation of Qingdao City, to develop appropriate measures to solve water shortage in Qingdao City.To fundamentally solve the problem of water shortage in Qingdao City, Qingdao City, under the mitigation of existing water supply capacity caused by urban development, water supply and demand, we must strengthen the conservation and protection of water resources, management of water quota as quickly as possible system, the development of industry and product water quota, and promote water-saving technological transformation and the popularity of water-saving appliances, according to Qingdao the current sewage treatment capacity, should be expanded in the next level on the scale of the use of recycled water to reduce the use of freshwater resources in the city and the city volume of sewage, the sustainable use of water resources.Paper made special mention of the reservoir to restore the building official way. In the next level because relying solely on local development and utilization of water resources can not meet the water demand of Qingdao, Qingdao City, coupled with no reliable back-up water, if you encounter a particularly dry year or other special circumstances, there will be serious situation of water shortage, Qingdao City in future years to address water shortages and protect the city safe water supply, inter-basin water transfer should be implemented as soon as possible to build a reliable back-up water, therefore, to restore the building official Road reservoir is necessary. Official Road Reservoir restoration construction, is expected to Qingdao City,30million of water a day m3, which not only in the local water supply can not meet the water demand effectively solve the case of water supply shortfall of Qingdao, Qingdao, can also provide a reliable back-up water protection.Also, according to the actual regime of Qingdao, you can also learn from foreign experience in water resources management, learn will help to improve the status of Qingdao, an effective method of water resources. For example, under favorable terrain coastal city of Qingdao, the use of seawater desalination and direct use of methods to reduce water usage. The face of Qingdao rich marine resources, sea water has caused the use of Qingdao City and community leaders at all levels concerns the development of the desalination industry and the sustainable use of water resources as an important means of inclusion of "national economy and Qingdao Social Development Five-Year Plan."2015,2020, respectively, through the desalination of sea water can be resolve Qingdao4,755,000m3,12.04million m3of water gaps, while the direct use of sea water can be widely used in urban industrial and domestic use.2015,2020, respectively, can be resolved directly by the sea in Qingdao City,29.93million m382.86million m3of water gap, which largely resolved in Qingdao, the level of water scarcity in the future.With the rapid economic and social development and increasing urbanization, the issue of water resource supply and demand are becoming increasingly aggravated water shortage has become the economic and social comprehensive, coordinated and sustainable development of the serious constraints. This paper, through investigation, statistical analysis of the industry over the years, Qingdao, the situation of water supply and demand data, Science2015,2020, Qingdao City, the layout of urban development and industrial demand of water resources and water supply according to the actual Qingdao2015and2020the ability to carry out water supply and demand balance analysis to find out the supply gap, to take water conservation, water reuse, water use and inter-basin water transfer and other measures to solve water shortage in Qingdao. The implementation of the program, not only to the next level of Qingdao to water supply and demand in balance, an effective solution to Qingdao in2015and2020the water supply gap, but the rest of the program can also solve the water shortage in coastal cities experience problems.
