    Abstract:
    With the three-dimensional wind fields and calculation on the path of an air parcel,the floating-dust shift caused by a sandstorm was tracked in opposite direction. The position of the floating-dust source and its three-dimensional path are determined. The result is consistent with the weather reports. It could be applied practically in determining the source of pollutants in the atmosphere.

    Abstract:
    According to the natural precipitation and actual water resource, the concepts of "natural aridity"and "actual aridity "have been sugge ted, which has made the .contribution to arranging the Gansu Loessial Plateau and the oasis in the Hexi Corridor under categories of climate and vegetation patterns. The results show that the patterns of climate and vegetation zones are comparatively coincided with those of their physical landscapes.
