The evaluation of flooding causality factors in the lower reaches of the Yangtze River is based on the data of 88 meteorological stations with complete daily precipitation series during 1980-2020, and the analysis of the change characteristics of the causality factors, such as the number of annual precipitation days and the average number of consecutive precipitation days, the concentration of precipitation, the number of days of torrential rainfall, and the amount of torrential rainfall in the lower reaches of the Yangtze River is carried out to provide the data support for the analysis of the resilience of the response to the floods in the next step. Data support was provided, while raster data at 0.1° resolution was obtained using inverse distance weight interpolation to provide a basis for analyzing precipitation changes on a spatial scale. Based on the day-by-day flow data from 1950 to 2020 at the Datong station, we analyze the change characteristics of the upstream water inflow; based on the day-by-day maximum tide level data from 1956 to 2020 at the Wusongkou tidal station, we analyze the change characteristics of the coastal tide level, which provides support for the analysis of the change characteristics of the flood causative factors.
