摘  要:
由于洪水这种自然灾害严重影响着正常的农业生产,该研究提出基于最小二乘支持向量机(LS-SVM)的洪水预报方法。利用LS-SVM泛化能力强、收敛速度快、预测精度高的特性,结合四川省自贡市某水文站实测水位和流量的数据,建立了单输入单输出(水位—水位)和双输入单输出(水位和流量—水位)2种洪水预报模型。结果表明:这2种模型都可以满足洪水预报精度的要求,并且双输入单输出(水位和流量—水位)模型的预报精度比单输入单输出(水位—水位)模型的预报精度高。

摘  要:
Since the flood natural disasters seriously affect the normal agricultural production,this paper gives a LS-SVM method for flood prediction. Using the features of strong generalization ability,fast convergence rate,high prediction accuracy of LS-SVM,combining with a hydrological station in Sichuan Zigong measured data of water level and flow set up a single input single output( water level-water level) and double input single output( water level and flow-water level) two kinds of flood prediction model. Experimental results show that both models can meet the requirements of flood prediction accuracy,and the accuracy of the double input single output( water level and flow-water level)prediction model is higher than the single input single output( water level-water level) prediction model.
