Zhang Guoming,Gu Wei,Wu Zhizheng,Shi Peijun. The Effect of Storm Surge on Soil Salt Content of the Farmlands along the Bohai Bay in China[J]. Advances in Earth Science, 2006, 21(2): 157-160.

On October 11, 2003, a huge storm surge attacked the Changzhou region in the Bohai bay of China. The surge smashed the shrimp breeding fields and flooded the coastal farms. These farms were inundated for a period from 10 days to 15 days. On May 3, 2004, a salinity analysis was carried out for the soil samples from the seawatersoaked farms. Result shows that these farms had all been salinized: 46% of the lands had alkali pots; the content of salts in the soil (0~90cm) had increased evidently while the salts mainly concentrated at the surface layer (0~10cm), where the salt content was as high as 1.134%; constitutes of saline ions at the 0~25cm layer also changed greatly: the Clincreased for 33.3%, while the Na+ and K+ altogether increased for 39.4%. It is found that rainfall is an effective and also primary way to desalinize these soils. Two years after the storm surge, salt content of the affected soils had dropped to around 0.265%, at which level some salt-enduring crops can be grown.
