沙尘和生物气溶胶的环境和气候效应

Environmental and Climatic Effects of Mineral Dust and Bioaerosol

沙尘气溶胶对海洋生态系统的影响及其气候与环境效应,以及生物气溶胶对人类健康的影响及其气候效应是近年来大气气溶胶研究的热点问题。沙尘气溶胶和生物气溶胶之间有很强的联系,沙尘可作为空气中微生物的载体,沙尘气溶胶影响海洋生态系统之后又会影响海洋上空生物气溶胶的产生。本文回顾了国内外沙尘气溶胶对太平洋海域生态系统影响的研究进展,以及生物气溶胶的研究历史和气候效应,特别是中国科学院大气物理研究所十多年来的有关工作。

Effects of mineral dust aerosol on marine ecosystem and impacts of bioaerosol on human health, their climatic and environmental effects are a hot issue in the study of atmospheric aerosols in recent years. There is a strong connection between dust aerosol and bioaerosol. Dust can be used as a carrier of airborne microorganisms. The formation and emission of bioaerosol over ocean can be affected by mineral dust deposited into the marine ecosystem. This paper reviews the researches of the impacts of mineral dust aerosol on marine ecosystem in the Pacific Ocean and the research history and climatic effects of bioaerosol, especially the works of the Institute of Atmospheric Physics, Chinese Academy of Sciences over more than ten years.
