河口、海湾生态系统初级生产力研究进展

河口及海湾生态系统与大洋生态系统相比,其理化环境因子复杂多样,且易受近岸人类活动的影响,生态系统多样性更高。初级生产力是河口及海湾生态系统研究的重要内容之一,也是渔业资源评估、水环境评价及生态环境治理等方面的重要参数。本文综述了近十年来河口及海湾初级生产力相关研究所取得的成果与进展,并从河口及海湾水域影响初级生产力的主要环境因子、初级生产力的粒级结构、赤潮机理研究、初级生产力估算方法等方面的相关研究对河口及海湾初级生产力的特点进行归纳总结,并对现在相关水域初级生产力估算的技术发展和研究重点进行了探讨和展望。

Progress in research on primary production of esturies and bays

Compared with the open marine ecosystem, the ecosystem of estuaries and bays have more diverse characters because of complicated environmental factors and anthropogenic impacts. Primary production is one of the research fields on the ecosystem of estuaries and bays, and is also an important factor on potential fishery evaluation, aquatic environmental assessment and management of environments. Research progress of primary production in estuaries and bays in the last 10 years are summarized. Detailed explanation and conclusion of recent reports on key environmental factors controlling primary production, the size fractionation of primary producer, the mechanism of red tides, evaluations of the primary production quantity are included in the paper in order to describe the characters and rules of the ecosystems, and discuss the development of assessment techniques and research focuses on primary production in the estuaries and bays.
