摘　　要：大气硫的沉降一直是人们很关心的问题,尤其是在区域尺度上的硫沉降问题一直是研究热点。发达国家最先开始有关于区域尺度硫沉降的研究,近年来我国也引进并建立了很多基于观测数据的各种模型来研究区域尺度大气硫沉降中的科学问题,并取得了可喜的进展。本文综述了区域尺度大气硫沉降机制和影响因素的相关研究进展,重点阐述了硫在大气中的迁移变化过程与污染源、气象条件、不同下垫面沉降速率对区域尺度大气硫沉降的影响并对今后该领域应开展的研究工作做了展望。Sulfur deposition at regional scale has been paid more and more attention to with accelerated acid deposition or acid rain worldwide. The study on sulfur deposition at regional scale has been initiated in developing countries. The sulfur deposition at regional scale by all kinds of models based on observation data in China was reviewed. This paper mainly summarizes the mechanism and influencing factors on sulfur deposition at regional scale. The transport of sulfur in the atmosphere and the effect of emission sources,meteorological factors and different land-use types on atmospheric sulfur distribution and deposition have also been discussed. At the end of this paper some new tasks in this field are proposed.
