The paper researched the wetland vegetation dynamics in the Yellow River Delta by the remote sensing and geographic information system technology. The study results showed that the land area of the closed regions with sea dykes was basically stable since 1995, and which of the open regions showed the diminishing trend from 1984 to 2006. The change trend of the area of the saline vegetation had increased from 1984 to 2006 and the change rate was 7.18. The change analysis of dynamic degree of wetland vegetation landscape revealed that the succession and conversion within the wetland vegetation landscapes was also one main process. The conversion rate of farmland was more than 12% in the two periods of 1984-1995 and 1995-2006, the human farmland reclamation activities in the coastal region had been on the rise.
