Dynamics of wetland and influence factor analysis of the Yellow River mouth area

This paper presents a data-based study of remote sensing images,sediment load and subaqueous bed forms including the application of techniques of remote sensing,geographical information system and correlation analysis in order to understand coastal wetland changes of the Yellow River Delta mouth.The wetland area of study zones has increased rapidly since 1996,but the changes of mudflat area are more complicated.The wetland area is controlled by many natural factors,such as Water Cut-off from the Yellow River,water and sediment load flowing into sea,the Yellow River course shifts,and coastal erosion and so on.In addition,human activities also have great effects on the wetland area changes.After realizing dynamics of wetland area and influence factor analysis of the Yellow River mouth area,the basic reference can not only be provided for environment construction and sustainable development of the region,but also has a very important significance for reasonable exploitation and protection of wetland resources.
