紫外线B对海洋生态系统的影响

本文根据国内外的相关研究资料，讨论了紫外线辐射(主要是紫外线B)对海洋生态系统中各个层次的海洋生物(包括浮游植物、细菌、底栖藻类、微型和小型动物以及养殖经济生物等)的影响及其对海洋环境中的污染物的效应，结果表明紫外线辐射不但对各类海洋生物有比较明显的直接作用，并且通过生态关系进一步影响到整个海洋生态系统的结构，对海洋生态系统造成威胁．

Effects of ultraviolet B radiation on marine ecosystem

Based on wide literature studies, this paper reviews the impacts of ultraviolet radiation (especially UVB) on various trophic levels of marine lives,including planktons, bacteria, benthic algae, micro- and meso-fauna, culturedlives, as well as on the fate of marine pollutants. The review shows that the ultraviolet radiation has not only direct influences on many forms of marine lives,but also on the structure of the marine ecosystems and further on the health ofthe marine ecosystem.
