Taking Hancang River watershed in Jinan City as an example, SWMM model is used to simulate the effect of macro-scale LID measures on hydrology and water quality of the basin under different rainfall intensities and different rainfall peak positions. The results show that with the increase in repetition period of rainfall, the effect of planning scheme of rainwater wetland system on the reduction of average discharge, peak discharge and pollutant load in the basin is gradually weakened. Under the same conditions of repetition period of rainfall, when the rainfall peak coefficient is small (r=0.4), the pollutant load is less, the peak discharge reduction rate is higher, and the delayed effect of the peak runoff is better, but the pollutant reduction rate is not affected by the single rainfall peak coefficient.
