| 摘要: |
| 以2003 - 2012 年厦门海域监测数据为基础, 参考美国第二代富营养化评价方法, 针对厦门海域实际监测特点并结合我国水体富营养化研究现状与评价标准, 进行部分改良, 使其更适用于该海域水体的富营养化状况评价。应用此评价体系, 本文研究了厦门海域水体富营养化压力程度; 以叶绿素a为初级症状指标、以底层溶解氧及赤潮发生状况为次级症状指标分析了水体富营养化的状态水平; 并通过结合厦门海域整治、人口增长趋势、经济发展趋势以及周边营养盐入海现状等因素预测了未来厦门海域水体富营养化压力变化趋势。结果表明, 厦门海域水体综合评价等级为中等富营养化程度, 其中压力等级为中高、状态和响应的评价等级均为中级。该评价结果较好地反映了厦门海域水体富营养化程度、压力和症状, 便于海洋管理部门对厦门海域环境容量进行监控与管理。 |

| Abstract: |
| Using long-term monitoring data from 2003 to 2012, We built an integrated and suitable method for the assessment of Xiamen coastal Waters based on American Phase II assessment procedures with modifications for Chinese situations. We studied the eutrophication pressure, analyzed the grade of overall eutrophic conditions including primary and secondary symptoms, and predicted the response trend in relationship to the economy, population, and nutrient input fluxes. The results show that, the integrated eutrophic grade in Xiamen coastal Waters was moderate, the eutrophication pressure was moderate to high, and the degree of eutrophication status and response were both moderate. The results are comprehensive, which not only reflect the overall degree of eutrophication but also contribute to the management for effective monitoring on the environment quality of the Xiamen coastal Waters. |
