Beschreibung
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, held in Nanjing, China in April 2005. Coverage includes: physical processes and their effects on shallow lake ecosystems; biogeochemistry of sediments and nutrient cycling in shallow lakes; and algal blooms and ecosystem response in shallow lakes.
