中文摘要：

以黄河三角洲东营市为研究区域,以湿地为研究对象,以多时相Landsat卫星遥感影像为主要数据源,在GIS技术支持下,对东营市湿地景观时空变化进行了动态分析.研究结果表明：10年间东营市的湿地分布及面积发生了明显变化,湿地总面积减少401.21km2.其中,天然湿地减少689.27km2,主要转化为人工湿地,尤其海涂共减少456.88km2.人工湿地增加288.06km2,面积增加最多的是海水养殖场,增加面积为187.31km2.人为干预是湿地动态变化的主要原因.

英文摘要：

With the support of GIS technology,a case study has been made on Dongying City in the Yellow River Delta region,allowing dynamic analyses of the temporal and spatial changes of wetlands in Dongying City by means of Landsat remote sensing images as the main data source.It has been found that the distribution and size of Dongying wetlands have changed during ten years,with the total wetland area decreasing by 401.21km2.The natural wetlands which decreased by 689.27km2 have mainly transformed into artificial wetland;in particular,the intertidal zone decreased by 456.88km2.By contrast,artificial wetlands increased by 288.06km2,among which the mariculture zone became the biggest winner with an increase of187.31km2.It can be concluded that human intervention is the main reason for such changes in Dongying.
