| 以北京市再生水灌区为研究对象,灌区再生水、地表水以及地下水的联合调度为研究内容,结合系统分析的思想,提出了再生水灌区水资源联合调度的数学模型。采用逐时段动态分析的方法,得出典型年北京市再生水灌区水资源的配置方案,其中特枯水年、枯水年、平水年和丰水年地下水开采量为21 626.08、14 616.39、11 928.83和7 262.05万m3,分别仅占全年总灌溉需水量的44.35%、37.61%、41.09%和34.04%。研究表明,通过联合调度有效缓解了灌区地下水过量开采的问题,同时提高了灌区的灌溉保证率,优化了供水结构,是一种科学可行的再生水灌区水资源联合调度方法。 |

| Choosing reclaimed water irrigation district in Beijing as the researched object, the combined dispatching
of reclaimed water, surface water and groundwater is studied. Binding with the theory of systematic analysis, it presents a mathematical model for united dispatching of multi water resources . Using the method of dynamic analysis, the distribu-tion schemes are achieved for the water resources in the irrigation district of each typical year. The results show that the groundwater supply amounts to 216. 1608 million m3 in very dry year, 146. 1639 million m3 in dry year, 119. 2883 mil-lion m3 in common year and 72. 6205 million m3 in wet year, while the proportion of groundwater for total irrigation water is only 44.35%, 37.61 %，41 .09% and 34 .04 %，respectively. It shows that through united dispatching we can effec-tively relieve the serious situation of over-exploitation of groundwater and improve the irigation guarantee rate, and the dispatching model is scientific and feasible. |
