Abstract
基于2001、2005和2010年3期TM遥感影像,运用GIS技术,分析了黄河三角洲不同区士或(Ⅰ区,刁口段;Ⅱ区,东营港及临近岸段;Ⅲ区,河口段;Ⅳ区,南部莱州湾岸段)潮滩盐沼的景观演变与海岸线变迁的动因关系。结果表明,岸线变迁直接决定了潮滩盐沼面积的增长或缩减,但其在不同区域的影响程度差异较大。2001-2010年,Ⅰ区由于1976年以后刁口流路废弃、水沙输入量锐减导致其岸线持续蚀退,潮滩面积锐减明显(减少57.64 km~2,减少率25.94%);Ⅲ区由于1976年以后黄河由清水沟或清8汉入海,河口区域的持续淤积状态使得岸线持续增长,潮滩面积增加显著(增加66.17 km~2,增长率17..
