摘要： 罗斗沙岛是我国首批公布的可以开发利用的无居民海岛之一,属于泥沙岛,岛体极不稳定,动态变化比较大。本文利用1973—2011年间12个时相的遥感影像,分析了罗斗沙岛近40 a来的动态变化情况。研究结果表明:近40 a来,罗斗沙岛的位置、形状和大小均发生了较大的变化。罗斗沙岛的动态变化可分为3个阶段:第一阶段(1987年以前),罗斗沙岛为一个完整的岛体;第二阶段(1987—2001年),罗斗沙岛被分为东北和西南两部分;第三阶段(2001年至今),罗斗沙岛的西南部分消失,仅剩下东北部分。本文的监测结果可为编制罗斗沙岛的海岛保护与利用规划、制定海岛开发利用的具体方案、提出海岛的生态保护措施等提供数据支撑,进而为罗斗沙岛的生态保护和相关部门对其进行海岛管理提供服务资料。

Abstract: Luodousha Island is one of the first batches of the nonresidential islands that can be used to exploit and utilize. Luodousha Island is composed of sands. Therefore, it is unstable and its dynamic changes are highlighted. We used 12 remote sensing images spanning from 1973 to 2011, to analyze the dynamic change of Luodousha Island. The research results show that its position, shape and area changed obviously during the past forty years. The dynamic change of Luodousha Island can be roughly divided into three stages. The first was before 1987 and the island was a whole. The second was from 1987 to 2001 and the island was composed of northeastern and southwestern components. The third was after 2001 and the southwestern component of the island disappeared. These monitoring results may provide scientific basis and supporting data for compiling the protection and utilization plan, formulating the specific scheme of exploitation and utilization, putting forward the environmental protection measures. And then they may serve the ecological protection and the related management of Luodousha Island.
