Dust storm hits North China many times during the spring in 2000

bringing adverse influence on the activities of both production and living. It is an effective technological method used to monitor the process of the dust

to research the spatial characters

and to analysis the under

s

urface of the dust by means of Remote Sensing and GIS. The scope and characters of dust storm ever having happened could be acquired by analyzing over twenty temporal images received by remote sensing satellite when the storm happened and proceeded. The region influenced directly by dust storm is estimated to be about two million square kilometers. Inner Mongolia

Hebei

Beijing

and Tianjing are the regions influenced by dust storm most frequently. In this article land use and its recent changes

soil characters

vegetation coverage

soil erosion

and natural environment of the region which dust storm passed through are put together to analyze by overlying the remote sensing data and spatial data. Dust storm in North China has a Multi

s

ource character. The region where this kind of damage concentrates has a spatial coherence with the Farm

p

asture region

the water and wind erosion region and the half drought region in North China. The increasing of human activity has a direct influence on the forming of dust storm. Then there comes the conclusion that the time and spatial characters of the environment that gives birth to the dust storm can be entirely known by people through Multi

s

ubject spatial data analysis. This analysis can provide objective spatial information in time for the establishment and actualizing of the laws about natural environment protection in order to release

or even avoid the dust damage. It also plays an important role in reducing the times that dust storm appears and decreasing the damage brought by this disastrous weather.
