Abstract: In view of the diversity and conformity of biology in the Yellow River estuary, and considered the influence of phytoplankton, sediment concentration, configuration of estuary, climate, and the change of season to the eco-environmental water requirements, a support vector machine (SVM) model used its powerful non-linear mapping ability to deal with input variables including concentration of chlorophyll, water level, runoff, sandiness and Sea Surface Temperature is set up, the quantificational study of the least eco-environment water requirements of seashore region in representative years for Yellow River estuary is realized, and the forecast results are compared with the BPNN output data.

Key words:Eco-environmental water requirements; Support vector machine; NN; Seashore region; Yellow River estuary
