Abstract:The Yellow River Delta is located on the west coast of the Bohai Sea. It is one of the regions with the most active interaction between land and ocean, and one of the three major estuary deltas in China. This region has the most complete, the most extensive, the youngest wetland ecosystem and abundant biological resources in China's warm zone. It plays an important role in regulating the climate, reducing exogenous pollution, restoring amphibious ecological ecotone, and other functions. In recent years, with the rapid development of the Yellow River Delta region, problems such as the continuous reduction of inflow seawater and sediment, the serious shrinkage of wetland areas, and the invasion of Spartina alterniflora Loisel, have become increasingly prominent. On the basis of summarizing and analyzing the development status of this region, we proposed four development concepts:ecological protection priority, adapt to local water conditions, deep integration of multiple elements, and reasonable spatial layout, then, suggested four development models:ecological farm and ranch, integrated development of fishery and tourism, integrated development of fishery and energy industry, and linkage of three kinds of industrial models, with a view to achieving green development of blue agriculture in the Yellow River Delta.
