流域-河口-近海系统氮、磷营养盐输移研究综述

Review of studies on nitrogen and phosphorus transport in the continuum of watersheds,estuaries and offshore areas

摘要: 综述了流域-河口-近海系统氮、磷营养盐的主要来源、营养盐输移的影响因素等方面的研究,介绍了当前营养盐输移研究的主要方法,并概括了氮、磷营养盐在流域-河口-近海系统的整体性研究。在此基础上,提出了该领域研究存在的主要问题及未来展望,强调了将流域、河口与近海系统作为一个整体,并充分发挥分布式模型的优势开展营养盐输移研究的重要性。

Abstract: The paper reviews the main sources of nitrogen andphosphorus nutrients, as well as their transports inwatersheds, estuaries and offshore areas.The leading methods of simulating nutrient transports are introduced, and the comprehensive studies on nitrogen and phosphorus transport in an integrated system of watersheds, estuaries and offshore areas are also summarized.Finally, the main problem sand future prospects on the issues of eutmphication are discussed, the couplingofwatersheds, estuaries and offshore areas should be focused, and the advantages of distributedmodels should be taken full in the study of nutrient transports in future.
