Abstract: The harnessing of Yellow River estuary is a very important part of the YR harnessing, which is related to the flood control safety of Lower YR and the economic and social development and the benign maintaining of YR delta ecology. This article analyzes the YR delta evolution since 1855 and the variation situation of flow course for different periods, while concludes the main harnessing process and harnessing measures of YR estuary. Viewing from requirements of keeping the healthy life of the Yellow River and ensuring the sustainable development of estuary region, it presents such countermeasures as to further enhance the engineering flood control construction, to stabilize the flow course of Qingshui Gully, to schedule the spare flow course, to well deal with the relationship between YR estuary harnessing and the economic and social development and benign  ecological maintaining, and to establish and perfect scientific management system, etc..

Key words: the Yellow River estuary; harnessing countermeasure; estuary flow course.
