Abstract
Raised field agriculture is a typical human-modified landscape of most shallow lakes and coastal saline-alkali areas in north China. Local farmers have constructed more than 9400 ha of raised fields for agricultural production in Baiyangdian Lake, the largest lake in the North China Plain. Most of the raised areas are 2- 4 m higher than the water level and 30-50 m wide. The canals surrounding these platforms are 2-10 m wide. The objective of this research was to obtain experimental information on a number of processes that affect the agricultural production of the raised fields system, such as the cultivation of Phragmites australis. Since aquatic plants mature in spring and summer, the field experiments were conducted in May, 2011. The ecological environment and economic benefits were analysed and it was concluded that raised fields have a positive impact on the control of water quality.
