Water environment safety has always been an important issue that plagues the healthy development of country's social economy. Low-impact development technologies have good resilience in dealing with water environment safety issues. Taking Cangzhou China-Europe Green Industrial Park as the research object, the rainstorm flood model and the rainwater resource utilization benefit model were established. The study found that green roofs have an obvious control effect on ground runoff. The reduction rate and control rate of the total runoff are 56.31% and 68.32%, respectively, and the peak flow reduction rate is 48.58%. The control rate for pollutants of TP, TN, SS and COD is 72.92%, 74.82%, 74.44% and 73.89%, respectively. However, with the increase of rainfall intensity, the runoff control rate and the pollutant concentration control rate decreased, showing a significant negative correlation between the fourth and fifth power functions. After calculation, green roof can produce better economic and environmental benefits.
