摘要

琼州海峡白沙门海滩是海口市重要旅游资源,历史研究表明自20世纪60年代以来其一直处于侵蚀退化状态。本文选取1994—2015年的19景Landsat遥感影像提取白沙门海滩水边线并计算海滩坡度,分析海滩冲淤,结果表明:1994—2008年海滩处于冲刷状态,高潮位的水边线平均向岸回退了104.71 m, 低潮位的水边线平均向岸回退了95.49 m,但是2000年附近时段的人工补沙弥补了海滩侵蚀退化;2008—2015年海滩转为淤积状态,高潮位的水边线平均向海前进了34.17 m,低潮位的水边线平均向海前进了25.52 m,海滩淤积可能是海滩东侧的新埠岛围填海工程造成的。

Abstract

The Baishamen beach of the Qiongzhou Channel is an important resource for the Haikou city's tourism, but the previous researches presented that it has been in erosion from 1960. The waterlines in 19 Landsat sensing images from 1994 to 2015 were extracted, which were used to calculate the beach slope and analyze the beach erosion and accretion. The results show that the beach was mainly in erosion from 1994 to 2008, the waterline moved 104.71 m to the shore near the high tidal level and 95.49 m to the shore near the low tidal level, but the artificial sand filling in the time around 2000 compensated the erosion. While the beach was mainly in accretion from 2008 to 2015, the waterline moved 34.17 m to the sea near the high tidal level and 25.93 m to the sea near the low tidal level, which may be induced by the Xinbu Island enclose engineering.
