| 摘 要： | 综述了沙尘暴研究的领域和进展，提出了利用NOAA/AVHRR数据提取沙尘暴信息和沙尘暴信息密度分割的方法，经与气象数据对比验证，结果比较满意。结合沙尘暴途经区域的土地覆盖类型和植被覆盖度，对我国北方典型沙尘暴与下垫面之间的关系进行了分析，认为在同样的气象条件下，沙尘暴途经地区下垫面的土地利用/覆盖状况和植被覆盖程度决定着沙尘暴的形成与强度的变化。

| Abstract: | This article summarizes the field and progress about the research of dust storm. The methods of extracting dust storm information and dividing dust storm information by density based on (NOAA/AVHRR data is provided. Compared with meteorological data, the result is satisfactory. By analysis the relationship between dust storm and surface (land cover and vegetables coverage degree) in Northern China, it is proved that the land cover and vegetable coverage degree have more relationship with the form of dust storm and change of its intensity in same meteorological conditions. |
