摘　　要：以2000年和2006年TM卫星影像为主要数据源,配合其它非遥感数据,在遥感与地理信息系统技术支持下,运用景观生态学原理,选取反映景观空间结构和景观异质性的指数,对大连地区湿地的整体景观格局和类型景观格局及其动态变化进行定量分析。结果表明:6年间,大连湿地面积减少了97.62km2;整体景观多样性指数和均匀度指数降低,优势度指数增加;各类景观格局时间序列上也存在明显差异性变化。湿地景观格局指数的变化,反映了移山填海工业园区的扩大及养殖业的大力发展等人为活动对景观格局的深刻影响。人为活动已成为大连市湿地景观格局变化的主要驱动因子。Two Landsat TM images（obtained in 2000 and 2006 respectively） were interpreted as basic information sources. The basic data of coastal wetland were obtained with the application of remote sensing and GIS-technique. The index reflecting the special structure and the heterogeneity of landscape pattern were selected by the ecological principle of landscape pattern. Those indexes were used to analysis the dynamic change of wetlands in Dalian. The result showed that the average fractal dimension index, fragment index and predominance index increased, but landscape diversity index decreased; and the area of wetlands in Dalian decreased 97.62 km^2 in the past six years. The change of wetland landscape pattern was a result of the expanding of industrial zone and development of the large-scale feeding. Human activity was the main driving force for the landscape change.
