| 摘 要： | 采用遥感和地理信息系统技术，根据遥感影像数据和实测水深数据，分析了现代黄河三角洲河口区滨海湿地面积的变化规律，并计算了研究区湿地面积与黄河入海沙量之间的相关性。结果表明，黄河改道清水沟流路初期，三角洲河口区滨海湿地面积呈快速增长之势，但滩涂面积变化较复杂，1996年实施清8出汉工程后，低潮线至水下-2，-5和-6m湿地...

| Abstract: | 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. |
