Chen Zhengyi Chen Jie. Discussion of Methods of Remote Sensing Analysis on Erosion Intensity in Hilly Loess Region of North Shaanxi Province[J]. Journal of Remote Sensing, 1992, (1): 9-16. DOI: 10.11834/jrs.1992002.
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.
