Effects of water depth and sediment nutrients on Vallisneria spinulosa in Lake Poyang

Journal of Freshwater Ecology, 2019
Poyang Lake, the largest freshwater lake in China, has experienced a large decrease in wetland area due to long-term overutilization and especially after the hydrological drought events from 2003. This outdoor study was conducted to elucidate the impacts
