Abstract: Based on historical and 2005-2006 field survey data, environmental impact assessment of Qingcaosha Reservoir construction project in the Yangtze Estuary was carried out. Results show that water quality in Qingcaosha is good, and the main indicators of water quality can meet the class Ⅱ of national surface water standard. There are 22 common types of plants in the study area with a vegetation cover of 11.3 km2. The aquatic biodiversity is high, and freshwater species are the main types of aquatic ecology. River basin pollution emissions, upstream runoff water quality deterioration, major construction projects and estuarine saltwater invasion may impact water quality of the reservoir. Reservoir operations optimization, delineation of source water protected areas, environmental pollution control and compensation strategy should be taken to protect the Qingcaosha area.
