摘要: 沙尘暴可通过起沙、传输和沉降过程将岩石圈、大气圈、水圈、生物圈和人类圈5大圈层有机地联系起来,成为研究全球变化及其环境效应的重要纽带和关键环节之一。在简单概述了沙尘源区和传输特征的基础上,主要针对沙尘对气候、环境产生的影响进行了讨论,揭示其背后隐藏的更广泛、更深刻的气候和环境效应。并就沙尘的“阳伞效应”、“冰核效应”和“铁肥料效应”的最新研究进展进行了重点阐述。结果表明沙尘暴像任何自然过程一样,对气候、环境及人类的影响也具有两面性。

关键词: 沙尘暴, 气候环境效应, 阳伞效应, 冰核效应, 铁肥料效应

Abstract: Duststorms can let the 5 spheres correlate closely by the processes of rising, transport and deposition of dust; they are atmosphere, lithosphere, hydrosphere, biosphere and human-sphere. So, duststorm becomes a main tache and a key chain in studying global change and its effects. On the base of simply summarizing dust sources and dust transport characters, we emphatically discussed the influence of duststorms on climate and environment, also reviewed the research advances on effect of duststorms, such as “sun umbrella effect”, “ice core effect” and “iron fertilization effect”. The results show that duststorm, as every natural process, has the double-face characters on the effects on climate, environment and human health and economy.

Key words: duststorm, effect on climate and environment, sun umbrella effect, ice core effect, iron fertilization effect
