篇1：基于Elman网络的黄河源区枯季径流预报研究
基于Elman网络的黄河源区枯季径流预报研究
采用反馈Elman网络对黄河唐乃亥及玛曲两站1959～年降水量及径流量进行了分析,建立了基于反馈神经网络的'黄河源区枯季径流预报模型.利用matlab7神经网络工具箱对黄河源区唐乃亥站枯季径流量进行了预报.结果表明,所建立的ANN(7,7,15,7)模型预报结果精度高,容错能力强,是枯季径流预报的有效手段.

土地覆盖与气候变化对黄河源区径流的影响
After dividing the source regions of the Yellow River into 38 sub-basins, the paper made use of the SWAT model to simulate streamflow with validation and calibration of the observed yearly and monthly runoff data from the Tangnag hydrological station, and simulation results are satisfactory.Five land-cover scenario models and 24 sets of temperature and precipitation combinations were established to simulate annual runoff and runoff depth under different scenarios. The simulation shows that with the increasing of vegetation coverage annual runoff increases and evapotranspiration decreases in the basin. When temperature decreases by 2℃ and precipitation increases by 20%,catchment runoff will increase by 39.69%, which is the largest situation among all scenarios.
