1990-2015年海上丝绸之路沿线30mLandsatTM/OLI海岸带红树林分布范围及其变化数据集

红树林是生长在热带、亚热带海岸潮间带或河流入海口，受到海水周期性浸没的木本植物群落，有着防风、防浪、促淤造陆、稳定海岸、保护海堤等的作用。基于中高分辨率卫星影像建立解译标志库，结合红树林特殊的生长环境，完成1990年、2000年、2010年和2015年海上丝绸之路沿线红树林分布范围。并获得两期数据的变化监测图。

Mangroves are woody plant communities growing in tropical and subtropical coastal intertidal zones or river estuaries, periodically inundated by seawater. They serve functions such as windbreak, wave attenuation, sedimentation promotion and land formation, coastal stabilization, and seawall protection. Based on medium-to-high resolution satellite imagery, an interpretation marker database was established. Combined with the special growth environment of mangroves, the distribution ranges of mangroves along the Maritime Silk Road were determined for 1990, 2000, 2010, and 2015. Additionally, change monitoring maps for two periods of data were obtained.
