Abstract
随着工农业的发展，沿海地区水体富营养化的程度加剧，严重威胁了海滨湿地生态系统的功能。本文综述了富营养化对盐沼外来植物竞争能力、盐沼植物群落演替、盐沼植物生长策略及沉积环境、盐沼植物对大气二氧化碳浓度增加的响应以及植物碳分配策略的影响等方面研究进展，总结了富营养化对盐沼的生态系统固碳潜力的效应及可能的作用机理，指出未来的研究方向。 With the development of human activities, more nitrogen and phosphorus are released into marine ecosystem, leading to heavier eutrophication, which threatens the function of the coastal wetland ecosystem. This paper reviewed the research progresses on the eutrophication affecting the salt marsh ecosystems including the effects of eutrophication on the alien plant competition ability, salt marsh plant community succession, salt marsh plant growth strategy and sedimentary environment, the responses of salt marsh plants to the atmospheric carbon dioxide concentration increase and the influence on plant carbon allocation strategy, discussed the effects of eutrophication on salt marsh soil organic carbon and its possible mechanism, and suggested the valuable research directions in this field.
