摘　　要：广西南流江口无居民海岛生态系统较为脆弱,自海岛地名普查以来,该区域海岛形态和岛体开发利用变化显著。文章基于2012-2019年共8期遥感影像,开展南流江口海岛形态和开发利用的遥感提取和变化检测,并逐年分析海岛变化情况。遥感监测结果表明:2012-2019年,南流江口10个海岛形态变化显著,面积减少约61.8%,2个海岛岛体新增开发利用变化;重点说明花轿铺、小砖窑岛和小平墩岛3个显著变化海岛的逐年变迁情况,并分析海岛变迁的主要原因,为海岛保护和管理提出若干建议。The ecosystem of island in Nanliujiang Estuary in Guangxi is relatively fragile,the islands had significant changes in morphology and island development and utilization since the investigation of islands in 2012.Based on the 8 phase remote sensing images from 2012 to 2019,the paper conducted remote sensing extraction and change detection of the morphology and island development and utilization of the Nanliujiang Estuary Islands,and analyzed the island changes in every year.The remote sensing monitoring results showed that from year 2012 to 2019,the morphology of the 10 islands had changed significantly with an area of about 61.8%reduction,and new development and utilization changes in 2 islands.The paper focused on the year-to-year changes of the islands named Huajiaopu,Xiaozhuanyao and Xiaopingdun.The paper analyzed the main reasons for the change of the island,and put forward several suggestions for the protection and management of the island.
