| Abstract: | Shuangtaizi estuarine wetland along the Bohai Sea coast, the biggest bulrush wetland in the world, has been listed in ‘The
Record of Important International Wetland Conservation District’. Taking the year of 2 000 as an example, the minimum, the
most suitable and the maximum ecological water requirement of Shuangtaizi estuarine wetland are calculated in this paper based
on both ecological theory and Geological Information System technology. In addition, the remote sensing technique is adopted
in the data acquisition process. Moreover, the total water requirement and the unit area water requirement for different wetland
types are obtained. The result is very important for water resources planning, ecological conservation and regional agriculture
structure adjustment in Shuangtaizi. Meanwhile, this study can serve as a useful example for calculating the ecological water
requirement in other similar estuarine wetlands. |
