摘要
海洋中“有机碎屑雨”的存在,早已引起国内外学者的重视。生物学家认为它为深海生物提供了食物来源(Harding,1974);化学家则认为它是海洋中物质转移的主要途径(Menzels,1974)。但是长期以来,由于实验技术未能解决,无法进行现场研究,因而这些论断均未得到证实。自70年代以来,沉积物捕捉器的使用(詹滨秋等,1991)开创了这个研究领域的新局面。现在不仅能够研究悬浮体的基本特性,而且可以了解它们在沉降过程中的动态变化。沉积物捕捉器的使用,在我国开始于80年代,主要用于浅海和港湾,
Sinking matter is a carrier of chemical elements in the sea for transfering. The paper is the result of the study on the sinking matter, which was collected with the sediment traps in the 15m and 68m depth water layers in the East China Sea at 32°00’N, 126°00’E, in May and July, 1990. The grade distribution of sinking matter and plankton in the whole water column, biological species and number, and contents of chemical elements, were analysed and examined. The results show that the grade distribution and biological species in the sinking matter were similar to that of plankton. The paper describes the spatial and temporal characters of metal element content in spring and summer, the relationships among the particulate metals arid the existence forms of the particulate metals in the sinking matter.
