中国沙尘暴分布规律及研究方法分析

Distribution Characteristics and Research Method of Sandstorms in China:A review

在分析中国沙尘暴研究现状的基础上,对其时空分布规律、沙尘源地、移动路径、研究方法和手段进行了系统的总结。结果表明,中国沙尘暴分布与北方的沙漠、沙地、戈壁等荒漠化地区分布一致,存在4大沙尘源区。干枯的湖泊、弃荒土地、沙砾草场可能成为东北地区的主要沙源,应引起注意;沙尘暴移动路径主要有3条,分别归纳了各路径的特征;根据沙尘源区示踪方法的特点和实例,指出了适用条件和应用范围,为今后沙尘暴的研究和防治提供依据和思路。

On the basis of published papers about sandstorms in China,we summarized the characteristics of the space-time distribution,sand sources and migration path of sand dust in China and the research methods.The review indicated that the distribution area of sandstorm was identical with distribution of the desert,sandy land and Gobi in northern China,and there were 4 main sand dust source areas.In particular,we pointed out that the dry up lakes,abandoned lands and gravel pastures all may turn to be main sand source areas for the sandstorms in northeast China.There were three main paths of sand storm migration and their characteristics were concluded respectively in the paper.According to the characteristics and application examples of the sand dust source area tracer method,we also pointed out their application conditions and scope.This will provided academic bases and references for further research and sandstorm prevention.
