Abstract:
Ansai country in Shanxi province is located in the
plateau of the northwest inland.
Its unique characteristics, terrain slope and summer rainy climate conditions,
and severe agriculture and human activities, all lead to serious soil erosion in
the region.
For the soil condition of the
Ansai country, this paper uses ArcGIS software to research
gully density,
and using WEEP software analyze the factors of the rill erosion which is the
main way erosion of Ansai country. Then the
results
show that the soil erosion of each
area
is very serious, belong to intense level. And the soil erosion in
each cultivated area gives a significance guiding for soil conservation.
Key words:
Macro monitoring extraction; Gully density; Model
simulation; Rill erosion
