孙德尔本斯湿地（Sundarbans Wetland of International Importance）是世界面积最大的红树林连续分布区，1992年被列为世界自然保护联盟（IUCN）国际重要湿地名录，编号为: 560。孙德尔本斯湿地位于孟加拉共和国西南海滨，濒临孟加拉湾，地处恒河、布拉马普特拉河与梅克纳河三河交汇处，湿地中心坐标为22&degN，89&deg31′E，列在国际重要湿地名录中的总面积为6017km&sup2。湿地内水系发育、潮汐河道纵横，动植物物种多样性丰富，包括大约300种植物和陆生，水生，两栖类和鸟类动物种群425种，其中一部分物种已经列为濒危物种。孙德尔本斯湿地红树林及其间潮汐河道每年面积有一定的变化，2015年红树林及其间潮汐河道总面积为4835km&sup2。该数据是在融合MODIS和Google Earth 影像数据基础上完成。数据以.kmz 和.shp 两种格式存储。

The Sundarbans Wetland of International Importance is the world's largest continuous mangrove distribution area. It was inscribed on the List of Wetlands of International Importance maintained by the International Union for Conservation of Nature (IUCN) in 1992, with the serial number 560. Located on the southwest coast of the People's Republic of Bangladesh, bordering the Bay of Bengal, the wetland lies at the confluence of the Ganges, Brahmaputra and Meghna rivers, with its central coordinates at 22°N, 89°31′E. The total area listed in the List of Wetlands of International Importance is 6017 km². The wetland features well-developed water systems and crisscrossing tidal channels, and boasts rich biodiversity, including approximately 300 plant species and 425 animal species spanning terrestrial, aquatic, amphibian and avian populations, among which some species are classified as endangered. The area of the mangroves and their associated tidal channels in the Sundarbans Wetland undergoes annual fluctuations; in 2015, the total area of mangroves and tidal channels was 4835 km². This dataset was compiled by integrating MODIS and Google Earth imagery, and is stored in two formats: .kmz and .shp.
