ABSTRACT
ABSTRACT: Diaokouhe River is one of the ancient channels of Yellow River Delta. Because of long-term no-discharge, the channel shape and ecosystem degenerate seriously. For saving and protecting the ecology and the environment of the channel, the governmental management department carried out artificial water supplement for the channel in 2010 and 2011. During the supplement period, some important index and data were observed and recorded systematically. The results indicate that the artificial water supplement had positive effects on the local ecology and the environment, such as preventing the saltwater intrusion trend in the degenerative estuarine wetland, controlling the rapid development of soil salinization, optimizing the ecological types and landscape structure, and improving and repairing the wetland biotope and bird habitats. However, some problems also exist, such as difficulty in transferring large amounts of water and huge accumulation of channel sediments.
