| Abstract: |
| 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. |
