The invention discloses a salinity forecasting method for a water intake of a river-side water source, which is characterized by comprising the following steps of selecting a proper runoff monitoringpoint at the upstream of the water intake of the river-side water source, and selecting a proper open-sea tidal range monitoring point at a river-water estuary; counting the daily salinity value of the water intake, and counting the upstream daily runoff volume and the open sea daily tide difference of the water intake at the two monitoring points respectively; establishing a mathematical model ofthe runoff volume, the open sea tidal range and the salinity of the water intake of the water source area, and fitting the established mathematical model to obtain an empirical relational expressionof the runoff, the tidal range and the salinity; and substituting the upstream daily average runoff volume and the open sea daily average tidal range obtained by the monitoring points into the relational expression to obtain th
