摘  要:
结合基于经典贝叶斯统计推断理论的MCMC(Markov Chain Monte Carlo)方法与多输入单输出模型,建立了不确定性水文预报模型,并将该模型应用于长江三峡水库,依据实验结果可得出以下结论:①较传统方法而言,不确定性水文预报可更好的避免由于模型的不确定性而引入的误差;②应用于三峡水库入库流量预报,实验结果表明预测流量可很好地覆盖实际观测流量,取得理想预报结果。

摘  要:
This paper combined the multi-input single-output model and MCMC(Markov Chain Monte Carlo)methods Based on the classic Bayesian statistical inference theory.The establishment of uncertainty hydrological forecasting model was applied in Three Gorges Reservoir,according to the experimental results can be obtained the following conclusions:① the uncertainty hydrological forecasting model can better avoid the uncertainty of parameters and the importing error than traditional methods;② apply to the Three Gorges reservoir Inflow forecasting,experimental results show that the flow can be predicted good coverage of the observed flow forecast to achieve the desired results.
