The Distribution of Dissolved Oxygen and Eutrophication Assessment in the Downstream, Estuary Water of Minjiang River

闽江流域在我国东南沿海具有重要地位，但由于种种原因，其研究程度和所受的关注度相对较低。近年来，随着闽江流域沿岸经济发展，其污染程度日益加重，不仅使流域水质恶化，更对沿岸生产生活带来不利影响，更进一步威胁近岸的生态环境。为了解闽江下游与河口水域溶解氧四季变化规律，综合评价其富营养化程度，探讨污染物源汇之间的输运通量情况，本文利用2014年8月~2015年5月期间，闽江下游水口水库，至河口表层水样，依据《海洋调查规范》等多项标准中的方法，对温度、盐度、溶解氧、高锰酸钾指数、化学需氧量（COD）、硝酸氮（NO3-N）、亚硝酸氮（NO2-N）、氨氮（NH3-N）、活性磷酸盐（PO4-P）等多项水质指标...Minjiang river has important position in southeasterncoast of China, but because of some reasons, there is low attention and researches paied on it. In recent years, with the economic development along the river, the problems of increasing pollutions become more and more serious. It not only makes the river water quality worsen, but also has negative influences on the production and living along t...学位：理学硕士院系专业：海洋与地球学院_海洋化学学号：2232013115138
