Abstract: Since the water supply crisis of Taihu Lake on May 29 ^th, 2007, a series of measures had been taken to improve the water supply, and achieved remarkable results. However, there were still some problems in Taihu Lake, such as the inflow pollution load greatly exceeded the water environmental capacity, the reed wetland was greatly reduced, and the cyanobacteria bloom erupted frequently. Based on the experience and lessons of Taihu Lake management, it was put forward that Taihu Lake management should innovate the integrated thinking of three kinds of technologies: Double Reduction/Double Increase technologies includes reducing point source, non-point source, and endogenous source caused by lake bottom sediment and cyanobacteria, and increasing environmental capacity and water self-purification capacity; Double Algae Removal technologies included blue-green algae fishing and algae suppression and killing; Double Recovery technologies included wetland and biodiversity restoration. Also, the goals of Two Elimination (eutrophication and cyanobacteria bloom) and Two Restoration (wetland and biodiversity) would be achieved, through the in-depth promotion and comprehensive establishment of the lake chief system, and the increase of applied science and technology and capital investment to ensure the effect of governance. Finally, some suggestions were put forward, such as revising the Overall Plan for the Comprehensive Treatment of Water Environment in Taihu Lake Basin, and setting up related research programme on the control and elimination of cyanobacteria bloom, including the goal of eliminating cyanobacteria bloom.
