Water Resource Management for Wetland Restoration Engineering in Tianjin Coastal Area in China

Abstract

Wetland is one of the most diverse ecosystem and important habitats. However, degradation and loss of wetlands increased with anthropologic factors. Thus, the research of wetland restoration has become the emphasis and imperative issue. Water plays an important role in ecological evolution of the wetlands, and water requirement is a key step for water resource management of wetland restoration engineering. This research deals with the analysis of water requirement for wetland restoration engineering in a case study in Bohai Bay. The results show that the total water requirement in the study area are (0.18~0.28)×109m3, (0.54~0.81)×109m3, (1.21~1.41)×109m3 to reach the basic objective, moderate objective and perfect objective, respectively.
