摘　　要：重点讨论近岸海域海洋资源开发过程中所诱发产生的次生悬浮颗粒物（Ｓ．Ｐ．Ｍ．）的产生机制，及其对近岸海域水体中生命元素（Ｃ．Ｎ．Ｐ．）的生物地球化学的行为、过程和内循环等诸环节的效应。该物质很大程度上决定了海域水体中的生命元素的存在形态、含量水平。因此，可能成为近岸水体富营养化的潜在威胁。We studied the process of marine environment resources development (Mainly the resources of productivity and purification ability) in the coastal area, in which the formation of the secondary suspended particulate matters is induced, especially the aquatic culture rises and domestic sewage discharges in the near shore zone.The following topics were emphasized: The mechanisms of the secondary S.P.M. formed; The buffering and controlling role in geochemical behaviour. process, fate and cycle of bioelement in water column; The effect on the kinetics of transformation among the various speciations,of bioelement and the content levels of nutrient in water. Therefore, it may turn into a potential source for the eutrophication in near shore water.
