Abstract Since the 1990s, climate has changed rather greatly in areas around Beijing. Of all the changes, the most
prominent is the increasing sandstorm days in winter and spring. As has been pointed out by many experts, resources
and environment are main factors responsible for forming a special kind of climate. In order to study
characteristics of land use in areas around Beijing, a special research project was set up to investigate
information on land use change and land degradation. This research was based on 3S (GIS, RS, GPS) technology. The
regularity and characteristics of land use change and land degradation in areas around Beijing are also analyzed in
this paper.
