浦东国际机场东移建在潮滩之上，少占用了土地，却也影响了长江河口的湿地生态环境。上海市非常重视市政工程建设与湿地环境保护的问题，通过在长江河口的九段沙岛实施种青引鸟的生态工程，补偿湿地被占用而失去的生态功能；在九段沙中沙和下沙共引种芦苇（Phragmite communis）和互花米草（Spartina alterniflora）90 hm²。经过3年连续监测，植物种群生长和扩散良好，鸟类数量有所增长，生态工程取得初步成功。

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,affecting the estuarine ecosystem. Shanghai seriously considered the contradiction between wetland ecosystem protection and land use in engineering construction. A related ecological engineering had been done on the Jiuduansha Island to compensate the lost ecological functions. The eco-engineering started on April 13 and ended on May 6, 1997.40 hm² of Phragmite communis and 50 hm² of Spartina alterniflora were planted in the 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 sets a precedent in the world.
