%X Taking the Yangtze River Delta Ecological Green Integrated Development Demonstration Zone as an example, based on the hydrological hydrodynamic model of the Taihu Lake Basin, a series of scenarios of changes in drainage capacity and scheduling rules are set up, and a trial calculation is carried out by taking the 1999 southern-type design rainfall of the Taihu Lake Basin as an input to obtain the water level process data of the main river satin surface and the maximum water level data in m of the major river channels in the Yangtze River Delta Ecological Green Integrated Development Demonstration Zone. Based on these data, the impacts of flooding situation within and adjacent to the city due to changes in drainage capacity and rules are analyzed, and finally the mutual feedback effects of cross-regional urban drainage are quantified based on the constructed drainage response index. City flooding capacity and scheduling rule changes can change the flooding situation within the city itself, Wujiang and Qingpu polder flood control pressure by the drainage capacity of the smaller, by scheduling water level adjustments to the impact of Jiashan is the opposite. Wujiang drainage capacity and Jiashan, Qingpu flood control pressure was positively correlated, drainage capacity changes, can significantly change the Jiashan, Qingpu dike outside the river flood control pressure; Qingpu and Jiashan drainage capacity changes in adjacent cities dike outside the river flooding situation to change the influence of smaller. Adjustment of the scheduling level has almost no effect on the flooding situation of the river outside the dike in two districts and one county. The flooding response index of the three cities in the demonstration area was generally negatively correlated with the flooding capacity; the flooding situation in Wujiang, Jiashan, and Qingpu had the strongest sensitivity to changes in the flooding capacity of Wujiang District, followed by Jiashan County.
