我国近岸海域富营养化评价新方法及应用

摘要

With reference to the Phase II methods for assessment of eutrophication status in estuarine and coastal waters used worldwide, and taking into consideration the ecological and environmental characteristics in coastal waters off China, a symptom-based method was established for assessment of eutrophication status in estuarine and coastal waters off China, with a framework of the Pressure-State-Response model. Application of the above method to the Changjiang Estuary indicated that the assessment result was the same as those of the main stream Phase II methods. Compared with the main stream Phase II methods, our method has advantages in easy availability of monitoring data, universality of application, and simplicity and ease of use.%参考目前国际上被广泛应用的第2代富营养化评价方法体系,结合我国近岸海域生态环境特点和监测资料现状,建立了一种以压力状态—响应模式为基本框架、以富营养化症状为主的第2代近岸海域富营养化评价体系.实际应用结果表明,应用本方法得出的长江口海域富营养化状况评价结论,与目前国外主流评价方法的评价结论一致,而且本方法具有评价指标代表性强、数据资料易得、评价标准有据、方法简便易行等优点.
