| 摘 要： | 基于1987—2015年Landsat遥感影像,运用ENVI与MapInfo软件提取岸线,分析红河三角洲近30年岸线演变规律,并结合历史岸线、红河多年径流量与输沙量,以及过境该海域多年热带气旋数量等数据,初步探讨红河三角洲岸线演变的影响因素。研究表明红河三角洲岸线在时间上呈前进与后退交替变化特征,其中巴拉特河口以南的岸段以后退为主,河口北部岸段总体以前进为主。巴拉特河口地区淤进与蚀退变化频繁,主要与上游建坝导致入海沙量变化以及台风造成的侵蚀有关。

| Abstract: | Based on the data acquired by Landsat remote sensing from 1987 to 2015,ENVI and MapInfo softwares are used to extract shoreline of the Red River Delta to follow up its evolution in the recent 30 years.Integrating the historical coastline together with the runoff and sediment budget of the Red River,and the number of tropical cyclones passing through the sea area in the recent years,the controlling factors of the coastline evolution of the Red River Delta are preliminarily discussed.The study shows that the coastline of the Red River Delta changes alternately with time.The southern part of the Balat estuary mainly retreats towards the land,while the northern part of the estuary mainly advances to the sea.The frequent siltation and erosion in the Balat estuary are mainly related to the change in sediment input caused by dam construction in the upper reaches and the severe erosion by typhoon. |
