摘　　要：大气汞是汞全球循环的组成部分,探索汞在大气中的时空分布对于研究其地球化学循环具有重要意义。本文综述了大气汞时空分布的研究现状,主要包括大气汞的来源,形态分布,空间分布及时间分布。研究表明,大气汞具有扩散范围广,空间变异大,时间变化规律性强的特点,同时还指出扩大时空分布研究范围和建立污染和预测模型是未来的研究重点。The atmospheric mercury is an important part of global mercury cycle.h is very significant to explore the temporal and spatial distribution of mercury for the research on geochemical cycle of mercury.This paper summarizes the studies on temporal and spatial distribution of atmospheric mercury. It mainly includes the sources, form distribution, temporal and spatial variability of atmospheric mercury. It indicates that atmospheric mercury has wide diffusion area, large spatial variability and evident temporal variability pattern. It is also pointed out that enlarging research areas of temporal and spatial distribution and establishing models are the research emphases in the future.
