| 摘 要： | 比之传统的调查方法，利用遥惑技术进行岸线解译具有范围大、多时段、省时、省力以及快速等优点。根据多时相TM遥惑数据，对闽江河口地区岸线进行解译，结合20世纪60年代地形图和2001年海图，分析了河口地区河道演变情况．对河流岸线和浅滩变化进行对比分析，发现闽江口南部水道多呈淤积状态，北边水道则为弱侵蚀型岸线；南部水下浅滩有新发育，原有的浅滩面积有很大的扩展，北边水道变化较小；文章最后对河道演变的影响因素进行了初步的探讨。

| Abstract: | Compared with traditional investigation methods,the remote sensing-based coastline interpretation method has its advantages of large range,multiple periods, time saving,labour saving and high speed.In this paper,the multi-temporal Landsat- TM images are used to interprete the coastline in the Minjiang estuary area and analyze the river channel evolutions in the estuary area in combination with the topographic map in 1 960 s and the marine chart in 2 0 0 1 . It is shown from the analysis results that most of the southern channels in the Minjiang estuary area were silted up,and the coastlines of the northern channels were weakly eroded;the underwater shoals in the southern part were developed in recent years and the shoal area has been extended greatly,but the changes in the northern channels were smaller.Finally,the factors affecting the river channel evolution are also discussed preliminarily. |
