大鹏湾海区营养盐年际变化及富营养化研究

Study on Eutrophication and Annual Change of Nutrients in Dapeng Bay

根据 1993—2003年 月、8 月和 月在大鹏湾海区 个站位的表、底层水样现场监测资料,分析 7 9 3了大鹏湾海区氮、磷营养盐的年际变化趋势。分别运用水质质量标准指数法、综合指数 WQI 法评价了大鹏湾海区水质质量。运用营养状况综合指数法进行了营养状况评价。结果表明,大鹏湾海区夏季的氮、磷营养盐水平较低,N/P 比值介于7～30 之间。

Based on the investigation information of July, August and September from 1993 to 2003 in Dapeng Bay, annual change of the nutrients in the Dapeng Bay is analyzed. The water quality status is assessed by the water quality index. The eutrophication in the Dapeng Bay is analyzed with a new model of classifying nutrient. The assessment results show that the nutrients' level is low, and the value of N/P is between seven and thirty.
