Study on Environmental Flows and its Evaluation Based on Eco-hydrology in Yellow River Delta Wetlands Sino-dutch Study Program YRD-EFS

Based on the principles of protecting integrity and stability of ecosystem, and aimed at promoting maintaining good situation of delta ecosystem, as well as improving the capacity and capability of the ecosystem and protecting biodiversity, this paper identified 23, 600 ha wetlands as restoration scale which urgently needed to be supplied with freshwater in the Yellow River Delta. Whereas, this study adopted the principle and methodology of landscape ecology, with the supporting of RS and GIS and wetlands plant physiology, ecology and hydrology, made a study on Coupling mechanism between water and ecological process therefore, established the Environment flow calculation and evaluation model which is based on eco-hydrology field of the Yellow River Delta; Furthermore, this study apply pre-scheme methodology and planning evaluation concept of landscape ecology decision & evaluation support system to forecast and evaluate ecological effects on the wetlands with different wetlands water discharge scenarios, which focused on the relationship study between suitable habitat conditions for indicator species such as Red-crowned crane, Oriental stork, Sauders gull and changing of ecological pattern after water supplement. In general, after fully took water resources, water allocation engineering measures and integrated requirement of wetlands ecosystem protection into account, this study proposed recommendation of supplying the Yellow River Delta wetlands with 0.35 billion m3/a freshwater abstracted from the Yellow River to restore and protect the Yellow River Delta wetlands ecosystem.
