Abstract: In this paper, hydrology, hydrodynamics and water pollution of shallow lake are analyzed. Gehu lake is one of the typical shallow lake located in the upstream of Taihu Lake basin in China and characterized by its multi-connected rivers and lakes in the river network. Several technologies and projects are put forward for pollution prevention and control, and water environmental protection, including water pollution control integration technology for the water systems of Gehu Lake, river-lake water quality and quantity regulation technology, ecological restoration technology for polluted and degraded water body, and water environmental integration management and optimization strategy. The main objectives are to: (a) stably and efficiently intercept and decrease the pollution load entering the lake through enhancing the river outlet ecological system structure function and water self-purifying capacity; (c) make Gehu Lake as a regulation system of water quality and water quantity in Taoge water system and guarantee that water quality of the flow into Taihu Lake from the upstream of West lake be further improved and the flow water be the clean water sources in the upstream area of Taihu Lake.
