In the topographically-broken gullied and hilly region of the loess plateau

we analyse the relationship among the density of gully

the developmental stage of gully

geomorphic form and soil erosion intensity with aerial photograph

and get some better results. Density of gully in this area is so high that it can reach 20km/km2; the erosive intensity varies with the different gully developmental stage; at the most active and densely gullied area

it has the most erosive intensity. According to the relationship between soil erosion total and erosion inensity

we set up a soil erosive model

divide multiple types of soil erosios using remote sensing image

measure erosive area and deposit total

and calculate the erosion intensity of varied erosive types with multivariate regression analysis methods

Finally we discuss some new teachnical ways to forecast regional erosive total.
