| 摘 要： | 以鄱阳湖区2个时相的M SS、TM遥感影像和1:5万地形图作为数据源,在具有最大信息量背景下,依据地物光谱、形态等影像特征对赣江河道变迁及三角洲成因进行了解译,发现河道的变迁主要表现为河流的改道和袭夺;采用人机交互式手段,利用多时相影像数据对赣江三角洲1976~1991年来演变进行了遥感动态监测,统计出15年间三角洲前缘新淤面积为37.6km2,整体淤积速度约2.5km2/a,且各部位淤积程度不一,并以中支淤积速度最快。

| Abstract: | Regarding 2-phase Remote sensing images of MSS and TM and 1:50000 relief map in Poyang Lake as data sources,the Ganjiang transition and delta evolution are interpreted in maximal information assembly based on the spectral signature and morphological character;Its was considered that river's transition mainly manifestated its diversion and capturing stream.By the means of human-computer intesaction,making use of the remote sensing image from 1976 to 1991,the dynamic monitoring of evolution in Ganjiang Delta was carried out,the increased area in delta front was 37.6 km2 and it is pushed forward at the speed of 2.5km2/a;Each part is pushed forward at different rate and the mud filling chiefly focuses on the Ganjiang's middle branch in delta front. |
