摘要
以2011年07月18日(天文大潮)象山港海域31个站位涨潮期和落潮期无机氮、无机磷、CODMn和叶绿素-a的监测数据为依据,运用模糊综合评价方法对该海域的富营养化程度进行评估。结果表明,目前象山港海域整体上水质富营养程度较高,符合三类水质标准。相比较而言,涨潮时港中水质相对较好,落潮时港口水质相对较好,在整个潮次期间港底水质富营养化严重。象山港水质目前的主要富营养化污染物为无机氮,其次是无机磷。
Based on the monitoring data of inorganic nitrogen ,inorganic phosphorus , CODMn and chlorophyll-a of 31 stations of Xiangshan harbor in July 18 , 2011 , analyze the seawater eutrophication degree with fuzzy comprehensive evaluation method . Research shows that Xiangshan Harbor has a overall higher degree of water quality eutrophication at present , compliance with water quality standards Ⅲ . In comparison , in the high tide period , the port water quality was better , while at low tide , the mouth of harbor with relatively good water quality , and water quality eutrophication of harbor bottom is serious during the whole tidal times . At present , inorganic nitrogen was the most main factor of the water eutrophication in Xiangshan harbor , and inorganic phosphorus was the second main factor .
