| 摘 要： | 根据甘肃省气候条件和地理环境十分复杂，河流站网密度低，面对上下游区间有正负入流量且没有观测资料，以水量平衡原理为基础的河道洪水演算无法进行的实际情况，立足于利用现有上下游水站的水情信息，在传统系统水模型和河道汇流理论有关原理、方法的基础上，提出了考虑区间正负入流量的自适应洪水预报模型，改进了现行系统输入～输出水量不平衡关系，解决了甘肃省河流洪水过程无法预报的问题。具有十分广阔的应用前景。

| Abstract: | Gansu Province is located at the northwestern China with a complicated weather condition and geography environment,the sparse runoff observation station is along the river ways,whereas above status,according to relational methods of conventional system hydrologic model and river network flow concentration theory a new flood forecast model called Auto-adapting Flood Forecast Model Considering with the Effect of Inflow into Reaches is established.In the model water storage variables and auto -adapting method of considering the effect of the inflow into reach are presented.So the lopsided relationship between input and output in the actual system is ameliorated and the problem of flood processing forecasting is solved by using the method.The results show that Auto-adapting Flood Forecast Model Considering with the Effect of Inflow into Reach es possesses a favorable application foreground on the arid and semi-arid areas in the northwestern China. |
