【 摘 要 】

The Taihu Basin is one of the most important areas which contains most of the wealthy metropolis of China. The frequent floods caused by extreme rainfall always bring economic loss and property casualties to the Taihu Basin. The backbone works of the Taihu Lake (BWTL) consisted of 11 mainstay projects are aimed at the basin management and flood control. The whole works begin in 1991, and are almost completed in 2002. We compare the two rain events in 1991 and 2016, and take two typical flood events as the case to analyse the effect of the BWTL in this paper. Due to the urbanization, more flood drains into the water body around the cities and causes the water levels of the control stations are higher than that in 1991. The BWTL changes the outlets of the flood water and improves the flood regulating capability of the Taihu Basin. Under the protect of the BWTL, even the continuous rain in 2016 brings the more serious flood than 1991, the Taihu Basin experience less flood loss.
