The rainfall series were extended to 2010.Under the land use of Taihu bhasin in 2010, the hydrological design resuls offlood control planning and water resources integrated plarnning were reviewed. The results show that the design rainstorm and designflood in different periods of Taiu basin are basically in accondance with those of flood control planming results, but the designflood of individual water conservancy partitions have been changed a lot because of the change of land use.The design anmualrainfall at different assurance rates are basically in accordance with those of water resources integrated planning results， but thedesign annual runoff and mean annual average runoff slightly increased because of the change of land use.
