The invention discloses a quantitative analysis method for river runoff change caused by climate change and human activities. The method comprises the steps of collecting hydrological and meteorological information, water resource evaluation data and human activity information in a basin, judging a mutation point of an annual runoff process, wherein the part before the mutation point is a natural stage of the basin and the part after the mutation point is an influence stage of the basin, the entire natural runoff sequence is reconstructed by using the hydrological and meteorological information of the natural stage, using hydrological model rating model parameters and then using meteorological information of the whole period, and analyzing the contribution of climate change and human activities to the river runoff change by using the difference between the reconstructed natural runoff and the actually measured runoff. By adopting the quantitative analysis method for river runoff change caused by climate change and human activities, in combination with situations such as hydrological and meteorological factor changes, land use changes and water use in the basin, the binary attribution analysis of the river runoff change caused by climate change and human activities is extended to quaternary attribution analysis of the river runoff change caused by rainfall change, climate change, land use change and water use.
