天津市国民经济一直高速发展,然而,我国北方水资源严重短缺,天津尤甚。天津市水资源人均量为160m~3,为全国的1/15,远低于世界公认的缺水警戒线(人均1000 m~3),与其社会、经济地位极不相称,严重制约着该地区的发展。水资源是支持天津市经济社会发展的不可或缺的自然资源。根据天津市经济社会可持续发展和生态环境保护对水资源的要求,以及本市水源条件,提出城市水源合理配置方案。如何高效使用南水北调来水,使有限的水资源更好地支持我市经济社会可持续发展,提高人民生活水平,保证城市供水安全。必须合理配置用水指标、确定城市供水系统总体布局及各类水源的相互补偿方式。根据供水条件划分供水分区,在调查了解各分区供水现状经济社会发展规划,以及对水资源的需求的基础上,按照人口、资源、环境和经济协调发展的原则,对城市可利用的水源(包括引滦、引江、当地地表水、地下水、再生水和海水利用等)用层次分析法进行了合理配置研究。运用层次分析法进行城市水资源配置,首先建立城市水资源配置层次模型。其总目标就是将可供水量进行合理配置,根据水源不同确定子目标。结合水源配置原则,进行层次模型准则层的架构。方案措施层为划分的受水分区。根据层次模型,针对目标层不同的子目标,分别进行配置求解。
The national economy of Tianjin is always developing in high speed, whileNorth-China is facing a series of problems caused by a severe shortageof water , especially Tianjin . The average amount of water resources apiece inTianjin is 160m3 , which is one fifteenth of our country . It is lower than waterdeficit warning (1000m3)that is accredited in the world. It is inappropriate withsocial and economic status. Water resources restrict development of Tianjin.Water resources that supports social and economical development in Tianjinis indispensable resource.Complying with the requirement of economic and socialsustainable development , biological environment protection on water resources,present water source in Tianjin , we study out reasonable allocation project onwater resources.How to do effectively utilize South-to-North water ? It is secured that thedrinking water quality shall be above class Ⅲ national standard and thereforepeople"s living standard shall be improved. Furthermore the demand of economicand social sustainable development for water resources shall be met. Reasonablyallocating water source confirms city"s overall arrangement of water supplysystem and balance ways of all water resources each other.Marking off the water supply sub area, researching economy and socialdevelopment programming and demands for water resources of every area, inaccordance with coordinative development of population、source、environmentand economy,we reasonably allocate available source by adopting analytichierarahy process (including Tianjin Luanhe River water resources 、South-to-North water transfers、surface water、groundwater、regenerative water、improvable sea water etc).We allocate water source by adopting APH . first,how to set level modle ofwater source allocation. the aim is to allocate reasonably available water supply.Confirming sub-object on the basis of different source, and linking to allocationfundamental of water resources, set model rule level, project level is sub area ofwater requirement.
