Eco-Engineering of Jiuduansha Island Caused by Pudong International Airport Construction in Changjiang Estuary, Shanghai, China

摘要

Pudong International Airport were suggested to be constructed on the tidal flats of the south bank of the Changjiang estuary, which could save some land, but also make some wetland changes to effect to the estuarine ecosystem. Shanghai seriously considered the contradiction between wetland ecosystem protection and land use in engineering construction. A relative ecological engineering could be done on the Jiuduansha Island to compensate the lost ecological functions. The eco-engineering started on April 13 and ended on May 6, 1997. Phragmite communis of 40 ha and Spartina alterniflora of 50 ha were planted in middle part of Jiuduansha Island respectively to improve its ecosystem structure, which acquired good effects. This kind of synchronous construction of both Airport and eco-engineering set a precedent for the world.
