2022年鄱阳湖湿地草洲生物量（春秋）

植物生物量是指单位面积湿地范围内存在的湿地植物的总重量，通常以鲜重或干重表示。湿地植物生物量是评价湿地生态系统健康状况、固碳能力和描述系统内 物质循环、能量流动过程的重要指标。植物生物量的变化与区域气候和水文条件的 变化密切相关。准确估计植物生物量对研究湿地生态系统碳循环和动态变化有着重要意义。
利用卫星数据，通过遥感估算模型对鄱阳湖春季和秋季草洲生物量进行反演，最后得到鄱阳湖植物生物量专题图共两张。验证表明，产品结果可信。
该数据为2022鄱阳湖湿地草洲春季（4月）和秋季（11月）的生物量信息，空间参考标准为WGS-1984_UTM_Zone_50N。

Plant biomass refers to the total fresh or dry weight of wetland plants per unit area within a wetland. Wetland plant biomass is a critical indicator for assessing the health status of wetland ecosystems, their carbon sequestration capacity, and for characterizing the processes of material cycling and energy flow within the ecosystem. Variations in plant biomass are closely associated with changes in regional climatic and hydrological conditions. Accurate estimation of plant biomass is of great significance for research on the carbon cycle and dynamic changes of wetland ecosystems.
Using satellite data, the biomass of marshy grasslands in Poyang Lake during spring and autumn was retrieved via remote sensing estimation models, and two thematic maps of plant biomass in Poyang Lake were finally produced. Validation results demonstrate that the product outputs are reliable.
This dataset provides biomass information of wetland marshy grasslands in Poyang Lake during spring (April) and autumn (November) of 2022, with the spatial reference standard being WGS-1984_UTM_Zone_50N.
