| 摘 要： | 利用不同时段的遥感影像、数字化地形图和历史航空相片,在地理信息系统平台上获取广西海岸线的时空变化资料,并对其进行分析。结果表明:(1)近50年来,广西海岸线总的长度减小,在1955—1998年期间岸线长度呈递减趋势;(2)岸线由曲折向平直化演变,其中围垦段的岸线相对平直;(3)风流岭江南岸及企沙东面鹿墩岛海岸的自然侵蚀幅度不大,岸线变形较小。

| Abstract: | Spatial and temporal data of the change of Guangxi shoreline were obtained and analyzed on the platform of geographical information system (GIS) by using satellite remote sensing images, digital topography maps and historical airplane photos in different periods of time. The results showed that: (1) the length of Guangxi shoreline has generally decreased in late 50 years, especially during between 1955 and 1998;(2)the shoreline is developing from zigzag to straight, especially the inning shoreline; (3) the shoreline to the south of the Fengliuling River and the shoreline around Ludun Island to the east of Qisha have been eroded slightly, the shoreline has changed less. |
