摘要
根据湄洲湾海域2005年丰、平、枯三个水期的海水监测及2005年9月的湄洲湾表层沉积物监测数据对湄洲湾的环境质量进行评价。结果显示，湄洲湾海域水质综合指数（WQI）全年平均为0．69，除了F1站位枯水期为1．04，轻度污染，其余的均小于1．0，全年综合评价为清洁，但受气候及水文条件的影响，丰水期和枯水期有两个站位呈富营养化状态；表层沉积物综合质量指标平均值为0．52，综合评价为清洁，但铜、砷、镉的单因子污染指数平均值介于0．5～1．0之间，说明表层沉积物已被这三个因子玷污。
According to the monitoring data of the Meizhou Bay＇s sea water during three periods including abundant, even, and dry times in 2005, as well as the monitoring data of Meizhou Bay＇s surficial sediment in September, 2005, Meizhou Bay＇environmental quality was estimated. The result showed that the water quality index（WQI） of Meizhou Bay was 0.69 the whole year on average. All of the data were less than 1.0 except the data of 1.04 at F1 station in dry time, belonging to first - degree pollution. The comprehensive evaluation was cleanliness. Affected by the climate and hydrographical condition, two measuring points appeared eutrophication at abundant and dry times. The surficial sediment＇s unified quality index was 0.52 on average, cleanly for the comprehensive evaluation, but copper, arsenic, and cadmium, these single- factors＇average pollution indexes were between 0.5 and 1.0, the sediment has been polluted by them.
