【摘要】：进入二十一世纪后，供水安全已成为举世瞩目的问题。我国是一个水资源短缺的国家，在很多地区，供水安全问题已经成为阻碍经济发展的主要问题之一，直接影响到我国社会经济的可持续发展及和谐社会的建设。近年来，随着城市化进程的加快，许多城市无法承载逐渐增多的城市人口和产业，需要寻求新的发展空间，从而使城市区域不断扩大，新建城市不断涌现。水资源短缺的问题会制约这些城市的发展，，因此，建新的城市时必须要确保供水安全。供水安全的研究具有重要的现实意义和深远的历史意义。本文以“兰州新区供水安全及水资源可持续利用”为主要研究方面，首先系统的分析了国内外研究现状，为论文研究奠定理论基础，其次分析了兰州新区自然地理状况、社会经济概况、水文水资源条件、水资源利用现状等基本概况，然后依据兰州新区规划方案运用指标分析法对其未来2015年、2020年、2030年的需水量进行预测，同时预测了新区未来的供水能力，对各水平年的水资源供需平衡进行预测分析。还对兰州新区的主要供水水源—引大入秦工程进行供水保障分析。最后，为保证未来兰州新区的供水可以满足未来城市发展的需要，结合新区水资源供需分析结果和兰州新区的现有条件和发展规划，提出了切实可行的对策、措施。论文主要包括下面的内容。 1、兰州新区2013年的年用水量为13192万m3，用水以农林灌溉为主，供用水季节性强，其中引大入秦工程供水11810万m3，占新区总供水量的89.5%，供水水源单一，供水存在安全隐忧。 2、对新区未来各水平年的给水工程统一供给水量和非给水工程统一供给水量分别进行了预测，相加得出未来各水平年的净用水量，再由新区水利用系数计算出相应的毛需水量，最后结合新区未来各水平年的供水能力进行水资源供需平衡分析。 3、新区水资源供需的预测结果为：新区2015年毛需水量3.295亿m3，可供水量为3.242亿m3，水资源需求量超过了供水能力，年缺水0.053亿m3，缺水率1.63%；2020年毛用水量5.083亿m3，可供水量为4.130亿m3，缺水0.953亿m3，缺水率23.08%；2030年毛需水量6.704亿m3，可供水量为4.712亿m3，缺水达1.992亿m3，缺水率42.28%。 4、引大入秦工程断水时新区的缺水情况很严重。预测2015年引大工程夏季断水时将缺水3530万m3，冬季断水时将缺水3429万m3；2020年引大工程夏季断水时将缺水4582万m3，冬季断水时将缺水8279万m3；2030年引大工程夏季断水时将缺水5844万m3，冬季断水时将缺水14007万m3。 5、对兰州新区的主要供水水源—引大入秦工程的水质进行评价，得出其水质较好的结论。然而当前引大入秦工程在输水过程中存在不少影响供水安全的隐患，急需采取措施提高工程运行的可靠性。通过分析，提出了有利于保障引大入秦工程输水安全的建议和措施。 6、通过探讨分析，提出保障新区供水安全及水资源可持续发展的措施建议。
[Abstract]:After entering twenty-first Century, the safety of water supply has become a worldwide problem. China is a national shortage of water resources, in many areas, water supply security has become one of the major problems hindering the development of the economy, directly affect the construction of China's social and economic sustainable development and harmonious society. In recent years, along with the city development speeding up, many city cannot bear the increasing city population and industry, need to seek new development space, so that the city area continues to expand, the new City emerging. The shortage of water resources will restrict the development of the city, therefore, the construction of the new city must ensure the safety of water supply has important practical significance. And the profound historical significance to research the safety of water supply.
According to the "Lanzhou New District water supply safety and sustainable utilization of water resources as the main research aspect, the first systematic analysis of the research status at home and abroad, which lays the theoretical foundation for study, followed by analysis of the Lanzhou area natural geographical conditions, social economic development, the water resources condition of hydrology, general situation of water resources utilization, and then on the basis of Lanzhou district planning scheme using the index analysis method to the future in 2020, 2015, for water demand forecast in 2030, and forecast the future of the new water supply capacity, water resources supply and demand balance in different years were predicted and analyzed. The main source of water supply - Lanzhou District of Yindaruqin project of water supply security analysis. Finally, in order to ensure the future of Lanzhou New District water supply can meet the needs of the future development of the city, with the area of water resources supply and demand analysis results and the present condition of Lanzhou New District And the development plan, put forward practical countermeasures, measures. The paper mainly includes the following content.
1, the annual water consumption of Lanzhou New District in 2013 was 131 million 920 thousand M3, and water and agriculture were mainly irrigated. The water supply and utilization season was strong, and the water supply to the Qin project was 118 million 100 thousand M3, which accounted for 89.5% of the total water supply of the New District. The water supply source was single, and the water supply had security concerns.
2, water for water supply engineering new area in the future in different years and unified supply water and non water supply project unified are predicted, adding that the future level of annual net water use by the district water use coefficient to calculate the gross water demand, finally to the district level years of water supply capacity analysis the balance of supply and demand of water resources.
3, the new prediction of supply and demand of water resources: new results for the 2015 gross water demand 329 million 500 thousand M3, water supply is 324 million 200 thousand M3, the water resources demand exceeds the capacity of water supply, water shortage rate 5 million 300 thousand years m3, 1.63%; 2020 gross water supply 508 million 300 thousand M3, 413 million m3, 95 million 300 thousand M3 of water shortage, water shortage rate 23.08% 2030 670 million 400 thousand M3; gross water demand, water supply is 471 million 200 thousand M3, water shortage rate reached 199 million 200 thousand M3, 42.28%.
4, Yindaruqin project when the water shortage situation is very serious. The new forecast in 2015 to lead a large project in the summer when the water shortage will be 35 million 300 thousand M3 in winter, when the water shortage will be 34 million 290 thousand M3 in 2020; the project in the summer when the water shortage will be 45 million 820 thousand M3 in winter, when the water shortage will be 82 million 790 thousand M3 in 2030; the project in the summer when the water the water 58 million 440 thousand M3 in winter when the water shortage will be 140 million 70 thousand m3.
5, the District of Lanzhou, the main source of water supply and water quality evaluation of the Qin project, the water quality good conclusion. However the Yindaruqin project has many effects in the course of the water supply safety risks, measures must be taken to improve the reliability of the operation of the project. Through the analysis, puts forward some suggestions and measures to ensure water safety water Qin engineering.
6, through the discussion and analysis, it puts forward the measures to ensure the safety of water supply and the sustainable development of water resources in the new area.
