摘　　要：三江平原是我国重要的内陆湿地分布区,开展湿地资源监测对湿地管理保护及可持续发展具有重要意义。基于GEE云平台对三江平原2010年、2020年湿地覆盖类型进行了遥感调查和驱动力分析:对Landsat系列多景影像进行了快速预处理,建立了契合研究区域的湿地分类体系,采用了以光谱特征和指数特征作为输入变量的随机森林算法,开展了三江平原近十年的湿地动态监测,并分析了其动态变化的驱动力。三江平原十年间湿地恢复显著,自然和社会多种因素驱动湿地恢复。Sanjiang Plain is an important inland wetland distribution area in China.It is significant to carry out wetland resources monitoring for wetland management and conservation and sustainable development.Remote sensing surveys and driving force analysis of wetland cover types in the Sanjiang Plain in 2010 and 2020 are conducted based on the GEE cloud platform.The Landsat series multi scene images are quickly preprocessed,the wetland classification system suitable for the study area is established,the random forest algorithm with spectral characteristics and exponential characteristics as input variables is adopted,the dynamic monitoring of wetland in Sanjiang Plain in recent ten years is carried out,and the driving force of its dynamic change is analyzed.The wetland restoration in Sanjiang Plain has been remarkable in the past ten years.Many natural and social factors drive the wetland restoration.
