Abstract
Nutrient limitation of phytoplankton growth in aquatic systems is moving towards a higher incidence of P and Si limitation as a result of increased nitrogen loading, a N:P fertilizer use of 26:1 (molar basis), population growth, and relatively stable silicate loading. This result will likely alter phytoplankton community composition, and may compromise diatom-->zooplankton-->fish food webs.
摘要
由于氮负荷增加、氮磷肥料使用比例为26:1（摩尔比）、人口增长以及硅酸盐负荷相对稳定，水生系统中浮游植物生长的养分限制正朝着磷和硅限制发生率更高的方向发展。这一结果可能会改变浮游植物群落组成，并可能损害硅藻→浮游动物→鱼类的食物网。
