海水中可溶性无机磷是海洋浮游植物生长所必须的成分之一,学者曾进行过较深入广泛的研究。影响海水中可溶性无机磷(以下简称磷)的含量及分布变化主要是生物、化学和物理等过程。当浮游植物大量繁殖时,磷能被消耗殆尽,有机体分解,可使生,海水垂直对流可将底层再生的磷带到上层,陆地径流也会将大量的磷带之再入海洋。本调查区包括南黄海和东海的北部区域,水系复杂(见第二章)。致使调查区水体中磷的含量及分布变化;亦较复杂,呈现明显的地区性和时间性,反映了浅海区域的特征。
Soluble inorganic phosphorus in seawater is one of the essential components for the growth of marine phytoplankton. Scholars have conducted a more extensive and extensive study. Changes in the content and distribution of soluble inorganic phosphorus (hereinafter referred to as phosphorus) in seawater are mainly biological, chemical and physical processes. When phytoplankton multiply in large quantities, phosphorus can be depleted and the organism decomposes, allowing vertical convection of seawater and seawater to bring the underlying renewable phosphorus to the upper layer, and land runoff also re-enters a large amount of phosphorus into the ocean. This survey area includes the northern areas of the South Yellow Sea and the East China Sea, with complex water systems (see Chapter 2). As a result, the content and distribution of phosphorus in the water bodies in the investigation area were also changed. It was also complicated and showed obvious regional and temporal characteristics, which reflected the characteristics of the shallow sea area.
