北海市近岸海域富营养化评价

Assessment on eutrophication of Beihai offshore

依据 1 991～ 1 996年北海市近岸海域水质监测资料 ,选用单项指标分析和营养状态指数法对北海市近岸海域的富营养化水平进行了分区评价。结果表明 ,廉州湾水质较差 ,受无机氮污染较重 ,廉州湾的营养水平明显高于南部近岸海域 。

Based on the monitoring result of water quality in Beihai offshore in 1991～1996, the assessment on the nutrient level in Beihai offshore was done, by the analysis on single item and the nutrient status index. The result shown that Lianzhou Bay water quality, which was more seriously polluted by inorganic nitrogen, was comparatively poor. The nutrient level in Lianzhou Bay was higher than in southern offshore sea water, some of which reached the eutrophication level.
