摘 要: 藻类对水体内生命元素的转化及其分布、迁移的影响,是目前水体内藻类生物地球化学研究的重点内容。藻通过光合作用和生物矿化,控制着C、N、Si、P、S、Ca等元素在水体内的循环;驱动着C和S在水体和大气之间的交换,进而影响大气中的C和S。藻生物积累及其对环境变化的及时反馈,使藻类成为地球化学环境变化的生物指示物。本文对水体内藻类的生物地球化学进行了综述。 Algae are important research objectives in the biogeochemisty studies.The influences of algae on transformation, distribution, migration of bio-elements within water body are key contents of biogeochemical studies by now. Algae control cycles of bio-elements C, N, Si, P, S, Ca within water body by photosynthesis and bio-mineralization. Algae urge exchanges of C, S between water surface and the atmosphere, influence the distribution of carbon and sulfur in the atmosphere as a result. Algal bioaccumulation and timely feedbacks to the environmental changes make algae become bio-indicator of environmental changes. Algal biogeochemistry within water body has been reviewed in this paper.
