Abstract:
Desertification is the consequence of a set of important processes
which are active in arid and semi-arid environments where water is the main
limiting factor of land use performance in ecosystem. The desertification phenomenon
with all the problems it cause, most great effect will remain in soil, so by
assessing soil variation, the researchers can reach the intensity of desertification.
For this purpose IMDP (Iranian Model of Desertification Potential Assessment)
a methodology that prepared by natural resources college, Tehran university
was used to determine map of desertification emphasize in soil criteria in mazayjan
region as arid that including EC, soil deep, soil texture and the amount of
sub soil gravel are recommended in order to assess the intensity of desertification
mazayjan basin. Subhumid area of Iran. Score of indices were recorded in different
work units. At last using the following formula
