Study on Evaluation of Effect of Ecological Water Regulated in the Yellow River Delta

  Diaokou River is one of the old courses of the Yellow River into the sea before1976 and its estuarine delta is an important part of the Yellow River Delta National Nature Reserve.To recover the increasingly degenerated ecology of the wetland in the estuarine delta of Diaokou River,the eco-water supplement to the wetland during the water and sediment regulation period was decided by the Yellow River Conservancy Commission in2010.In this study,taking Diaokou River as one of case study,the effects of the Yellow River ecological water regulation were evaluated,and the follow-up assessments and analyses on the factors such as vegetation,wetland,soil salt content,ground water,etc.before and after the eco-water supplement are made with the methods including the real-time monitoring,remote sensing image interpretation and ground water model simulation concerned.The result shows that the eco-efficiency of the eco-water supplement to Diaokou River is remarkable,which not only preliminarily impedes the developing trend of the invasion of salty groundwater into the degenerated wetland area of the river,but also alleviates the soil salinization within the region to a certain extent,i.e.the damaged sensitive habitat and the wetland vegetation structure are restored along with the preliminary formation of the reed marsh and reed meadow——the suitable habitat for the aquatic birds and the obvious increase of the biodiversity of the aquatic birds therein.
