Modeling impacts of drought-induced salinity intrusion on carbon fluxes and storage in tidal freshwater forested wetlands

A biogeochemistry model was developed to examine plant gross primary productivity (GPP), net primary productivity (NPP), plant respiration, soil respiration, soil organic carbon sequestration rate and storage under scenarios of drought and normal conditions at Tidal Freshwater Forested Wetlands (TFFW) sites along the Waccamaw River and Savannah River in the Southeastern United States.

本研究开发了一款生物地球化学模型，用于分析美国东南部瓦卡莫河（Waccamaw River）与萨凡纳河（Savannah River）沿岸的潮汐淡水森林湿地（Tidal Freshwater Forested Wetlands, TFFW）站点在干旱与常态两种情景下的植物总初级生产力（gross primary productivity, GPP）、净初级生产力（net primary productivity, NPP）、植物呼吸作用、土壤呼吸作用、土壤有机碳固存速率与土壤有机碳储量。
