【摘要】 利用2003年3月和6月对南麂列岛附近海域潮间带环境质量调查结果,采用环境质量单项评价标准指数法,对该海域潮间带水环境质量现状进行了评价与分析,结果表明:(1)该海域潮间带水质的pH值、溶解氧、化学需氧量和石油类物质均符合一类海水水质标准,春季时无机氮和活性磷酸盐超标较严重,绝大部分海域水质达不到一类海水水质标准,夏季时仅个别站位水质的活性磷酸盐未超标;(2)该海域营养盐结构中N/P值很高,活性磷酸盐是非常敏感的生源要素,它在海水中含量的变化可能会影响整个海域的生态系统。更多还原

【Abstract】 The water environmental quality in the sublittoral intertidal zone near Nanji Archipelago was investigated in March and June, 2003.Environment quality standard index method is adopted to evaluate the present environmental quality in the intertidal zone.The results show that pH,DO,COD and Oil all coincide with the first grade sea water quality standard. In spring, TIN and PO₄-P severely exceed the standard. In summer, PO₄-P in some of the sampling stations was above the standard.The N/P in the structure of the nutrients was very high. PO₄-P was the highly sensitive biogenic element of the ecosystem in this sea area,and its content change in the seawater would be likely to have an effect on the environment in the entire sea area.更多还原
