摘要: 在海洋生态动力学研究过程中,采用浮游植物细胞数量来估算浮游植物丰度可以说是不够精确的,因为不同种的浮游植物细胞大小差别很大,只有浮游植物的生物量才能正确反映海洋生态系中的能量分布.本文以拟合浮游植物细胞相似体积方法,基于胶州湾生态动力学研究所获资料,计算了87种中国近海常见浮游植物的细胞体积、鲜重、碳含量、氮含量.Abstract: Cell size differs greatly between species of phytoplankton.The routine estimation of standing stock as cell numbers is therefore an imprecise and sometimes even inadequate measure of phytoplankton abundance, only the biomass can represent the energy distribution in ecosystem more precisely.The relationship between cell carbon and cell volume has been sought in order to estimate phytoplankton carbon in seawater from preserved phytoplankton samples.Bases on the original data of the Jiaozhou Bay Ecosystem Dynamics, cell volume calculations for 87 phytoplankton species were analyzed for the China sea and we calculated the cell size, five weigh, carbon content and nitrogen content of phytoplankton.
