摘要
根据光照、水温、营养盐对浮游植物生长影响的研究结果,综合分析光照、水温、营养盐影响浮游植物生长的变化和其集群结构的改变,探讨了上述因子影响浮游植物生长的生理特征和其集群结构的改变特点。本文阐明光照、水温和营养盐对浮游植物生长影响的机理和过程,确定了它们对浮游植物生长重要影响大小的顺序,由小到大的重要影响程度依次为:光照、水温和营养盐Si。这样,在人类的活动中,首先要考虑输入大海的营养盐Si,其次要关注海洋的水温变化,为海洋生态的持续发展做出积极的贡献。
According to the study results of the effect of light, water temperature and nutrients on the phytoplankton growth, the influences of the light, water temperature and nutrients ob the variation of phytoplankton growth and change of its assemblage structure were synthetically analyzed. The physiological characteristics of phytoplankton growth and the change profiles of its assemblage structure influenced by light, water temperature and nutrients were studied. The mechanism and process of the effect of light, water temperature and nutrients on phytoplankton growth were clarified, and the magnitude order of their effects was determined. The degree of the important influence from small to large was ordinal： light, water temperature and nutrient Si. Therefore, in the humang activities, firstly, the transportation of silicon into the sea was considered, secondly, the variation of the marine water temperature. It should make an active contribution for the sustainable development of the marine ecology.
