| 摘 要： | 纵观20年来，特别是近几年来逐渐成为生物地球化学循环研究热点之一的大气对海洋物质输入的研究，从大气物质入海通量，大气物质入海对海洋生态系统和环境的影响，大气物质入海的科学研究计划和项目等方面分析了这一领域的研究现状和未来趋势。给出了不同海区各种主要大气入海物质的通量或在同类物质入海总量中的比例，讨论了氮、磷、铁等营养物质和持续性有毒污染物，如PAH、PCBs、杀虫剂和重金属对海洋生态系统和环境的不同影响。

| Abstract: | The study of atmospheric inputs to the sea has become a new focus of biogeochemical cycle in the past few years. Fluxes of atmospheric pollutants to the sea, the effects of atmospheric input on marine environment and ecosystem, and study projects on this point are reviewed. The atmospheric deposition fluxes/proportions of atmospheric versus riverine inputs of nutrients, aerosol, heavy metals and some persistent organic pollutants (POPs) are given. It is shown that the amount of nitrogen from atmosphere to the sea is about 20%~50% of the total input from atmosphere and rivers, and the atmospheric inputs of PAH, PCB, DDT and heavy metals, such as Pb, Cd, Cu, Fe are 50%~80% of the total inputs. The different effects of nutrients, such as nitrogen and phosphorus, heavy metals and POPs, such as PAH, PCBs and pesticides on marine environment and ecosystem are discussed. Nutrients, nitrogen and phosphorus from atmosphere deposition are important factor to enhance new primary production in open seas, but have some positive influence on the nutrificated coastal oceans. More and more species of POPs and heavy metals are detected in water and sediment in the sea, which may prevent the production of phytoplankton and change the natural structure of marine ecosystem. |
