本研究的目的是开发和验证一个特定生境的生产模拟模型，以量化每年的底栖微藻生产在北湾河口，南卡罗来纳州。使用每小时测量的入射辐照度在1990-1991年的强迫函数，模拟模型被用来获得每小时的估计面积底栖微藻总初级生产力在5个生境类型。该模型，这是使用生产的实际测量结果进行验证，显示出良好的（r2= 0.63，P < 0.001）之间的协议观察和预测的生产在短互花米草Loisel区栖息地显示最高的平均每小时生产量（61.1毫克C m−2小时−1），而潮间带泥滩有最大的每小时速率（166.9毫克C m−2小时−1）。每日产量变化很大，主要是由于辐照度的每日波动。将特定生境产量的年度估计值乘以特定生境产量的mates，再乘以每种生境类型的已知面积，以确定河口的总微藻产量（3.423 × 109 g C yr−1）。短米草区生境提供了45%的总微藻年生产量，其次是潮间带泥滩（22%），高米草区（18%），浅潮下带（13%）和微藻生产超过浮游植物和微藻生产，但小于米草生产。
The purpose of this study was to develop and validate a habitat‐specific production simulation model to quantify annual benthic microalgal production in North Inlet estuary, South Carolina. Using hourly measurements of incident irradiance during 1990–1991 as the forcing function, the simulation model was used to obtain hourly estimates of areal benthic microalgal gross primary production in five habitat types. The model, which was validated using actual measurements of production, showed good (r2= 0.63, P < 0.001) agreement between observed and predicted production in the short Spartina alterniflora Loisel zone habitats showed the highest mean hourly production (61.1 mg C m−2 h−1) while intertidal mudflats had the maximum hourly rate (166.9 mg C m−2 h−1). Daily production was highly variable, primarily due to daily fluctuations in irradiance. Annual estimates of habitat‐specific production were multiplied by the mates of habitat‐specific production were multiplied by the known area of each habitat type to determine total microalgal production for the estuary (3.423 × 109 g C yr−1). Short Spartina zone habitats provided 45% of total microalgal annual production, followed by intertidal mudflats (22%), tall Spartina zones (18%), shallow subtidal (13%) and microalgal production exceeds phytoplankton and microalgal production but is less than Spartina production.
