Estimating Soil Erosion in North China Plain Based on RS/GIS and RUSLE
Estimation of soil erosion is of great importance for ecological protection and erosion control in the major grain producing areas of the North China Plain.Based on geographic information system(GIS)
the revised universal soil loss equation(RUSLE) was employed to assess quantitatively soil erosion in the North China Plain by incorporating the interpreted data from remote sensing images
digital elevation model(DEM)
soil map and rainfall data.Furthermore
the spatial distribution of the soil erosion intensity has been obtained.The results indicated that the annual average soil erosion modulus was 2 674.26 t/(km2·a) with the maximum of 8 302.11 t/(km2·a)
which can be classified as overall moderate according to the national standard.The areas which under the mild range accounted for 82.94% of the study areas
suggesting that the soil loss was under control.Approximately 7.33% of total area was still on the severe range
especially in the rocky mountainous areas along the Taihang Mountains
Yanshan Mountains
Tai Mountains
and Dabie Mountains
the key areas where soil erosion are yet to be controlled.
