摘　　要：根据1999年10月至2000年9月对广东柘林湾每月一次的监测结果,分析了柘林湾海域氮磷的分布特征和来源,并用营养状态质量指数(NQI)法评价了增养殖区的营养水平。结果表明:柘林湾海域氮磷的分布特征表现为西、北部海区大于东、南部海区,近岸高于离岸的基本格局,其主要来源为陆源排污和海水养殖自身污染。目前,柘林湾整个海区处于严重富营养化水平。From October of 1999 to September of 2000, monthly marine environment monitoring was conducted in Zhelin Bay of Guangdong Province. The monitoring data was analyzed and the method of nutrient quality index （NQI） was used to assess theeutrophication extent of Zhelin Bay. The results showed that： the nitrogen and Phosphorus content in Zhelin Bay were higher in the west and north than the east and south sea area, and higher in inshore waters than the off shore waters. Nitrogen and phosphorus elements＇ enrichment was mainly caused by the terrestrial pollution and self pollution of mariculture. At present, the whole sea area of Zhelin Bay is on a severe eutrophication level.
