| 摘 要： | 地表起尘和大气降尘在大气圈、陆地表面和海洋间的物理和生物化学交换过程中起着重要作用,该交换过程从地质历史时期以来一直延续至今。对大气降尘的研究具有重要的理论和实践意义。在阐述了大气粉尘的形成、传输、沉降机制及理化特征的基础上,着重论述了大气粉尘的源区、降尘的时空分布、环境效应及与黄土堆积的关系等,并提出了目前大气降尘研究存在的问题及研究展望。

| Abstract: | Dust emission and deposition are important exchange process between atmosphere,earth-surface and ocean,which have continued from geological period to today.Rsearch on dustfall has important theoretical and practical meanings.At the base of setting forth the formation,emission and deposition mechanism of aeolian dust and its physical and chemical characteristics,we emphatically analyzed the source,temporal and spatial distribution,environmental effect of dustfall,and the relation between loess deposit and du... |
