Eutrophication and algal blooms are worldwide environmental issues in lakes. The eutrophication process and formation mechanisms of algal blooms are particularly complicated in shallow lakes due to the strong lakeland, airwater and watersediment interactions. This volume features papers presented at the International Symposium on the Eutrophication Process and Control in Large Shallow Lakes with Special Reference to Lake Taihu, a Shallow Subtropical Chinese Lake, held in Nanjing, China, 2226 April, 2005. The topics include: physical processes and their effects on shallow lake ecosystems; biogeochemistry of sediments and nutrient cycling in shallow lakes; algal blooms and ecosystem response in shallow lakes; eutrophication control and restoration in shallow lakes; and resource exploitation, environmental protection and sustainable management in shallow lakes.

This volume will make a significant contribution to the understanding and management of eutrophication in shallow lakes.
