Extreme Drought in Grassland Ecosystems (EDGE) Seasonal Biomass and Seasonal and Annual NPP Data at the Sevilleta National Wildlife Refuge, New Mexico

Net primary production is a fundamental ecological variable that quantifies rates of carbon consumption and fixation. Estimates of NPP are important in understanding energy flow at a community level as well as spatial and temporal responses to a range of ecological processes. While measures of both below- and above-ground biomass are important in estimating total NPP, this study focuses on above-ground net primary production (ANPP). Above-ground net primary production is the change in plant biomass, including loss to death and decomposition, over a given period of time. Volumetric measurements are made using vegetation data from permanent plots collected in SEV297, "Extreme Drought in Grassland Ecosystems (EDGE) Net Primary Production Quadrat Data" and regressions correlating biomass and volume constructed using seasonal harvest weights from SEV157, "Net Primary Productivity (NPP) Weight Data."净初级生产力（Net Primary Production, NPP）是量化碳消耗与固定速率的核心生态变量。NPP的估算对于解析群落水平的能量流动，以及各类生态过程响应的时空格局均具有重要意义。尽管地下与地上生物量的测量对总NPP的估算至关重要，但本研究聚焦于地上净初级生产力（Above-ground Net Primary Production, ANPP）。地上净初级生产力指特定时段内植物生物量的变化量，包含死亡与分解所造成的生物量损失。本研究借助SEV297数据集"草原生态系统极端干旱（EDGE）净初级生产力样方数据"中永久样地的植被数据开展体积测量，并利用SEV157数据集"净初级生产力（NPP）重量数据"中的季节性收获重量，构建了生物量与体积的相关回归模型。
