Effects of restoration engineering on the soil seed banks of typical communities in wetlands converted from farmlands in Nansi Lake, China

摘要

Wetlands are valued for providing a range of ecosystem services. However, approximately 50% of global wetlands have been lost since the 1900s, with agricultural development being one of the main causes (An et al 2007, Jarrod era/ 2010). Converting farmland to wetland is one of the most popular methods of restoration engineering in China. The study on seed characteristics responding to the restoration engineering is important for better understanding the ecological succession of the restored wetlands.
