摘要
沙尘物质对全球气候变化具有重要影响,其源区示踪已成为全球环境变化研究的热点问题之一。从矿物学、元素地球化学、同位素地球化学等方面综述了国内外对沙尘源区示踪方法的研究现状,同时介绍了现代尘暴事件、中国北方黄土、冰岩芯和深海沉积物沙尘源区分布的研究进展情况,并对研究中存在的问题进行了讨论,希望对这方面研究有所裨益。
Aeolian dust affects significantly global climate change, and its source area trace has already become as one of the focuses in researching global environment change. In this paper, the domestic and foreign research progresses of the trace methods of dust source areas are reviewed from the aspects of mineralogy, element geochemistry, isotope geochemistry, etc. Moreover, the new research progresses of the distribution of modern sandstorm events, dust source areas, loess in north China, ice cores and pelagic sediments are discussed. The study results show that many domestic and foreign research achievements about the trace methods of dust source areas, especially about the application of high-accuracy geochemical methods, have been achieved by using various study means, most of the study results, however, were speculated. Some problems in researching the distribution and the geochemical trace methods of dust source areas in north China are analyzed. It is considered that the study on the geochemical background of the latent dust source areas in China is not so thorough and comprehensive, and the study results of tracing the latent dust source areas using geochemical methods are not so significant.
