沙尘溯源方法研究进展

Research Progress in Traceability of Dust

沙尘与人类生产和生活密切相关,既有增加降雨、减缓气候变暖、提高海洋浮游生物生态系统净初级生产力(NPP)等功能,同时也有污染空气、影响人类健康、危害农林业及交通等副作用,所以沙尘溯源是荒漠生态学领域研究热点之一。文中综述了国内外沙尘溯源研究历史及其现状,介绍了物理、化学、同位素等研究方法,在系统分析的基础上指出沙尘溯源研究存在的问题及其研究展望,目的在于探寻沙尘溯源研究途径,为我国沙尘暴预报、沙尘源区健康管理、减少沙尘暴危害等提供参考。

Dust is closely related to human well-being, functioning to increase rainfall, slow global warmingand improve the marine plankton net primary productivity, but also leading to increased air pollution,negative effects on human health and harm to agriculture, forestry, industry and transport. So the study ofdust traceability is one of the neighborhood hotspots of desert ecology. This paper reviewed the history andcurrent situation of research on the traceability of dust by introducing the physical, chemical, isotopic andother methods for the .research. On the basis of a systematic analysis, the problems arising in the dusttraceability research is identified and the development trend in the research is also prospected. This researchis aimed at exploring new approaches to the research on dust traceability and providing references tosandstorms forecast, health management in dust source region, and sandstorms harm reduction.
