Based on the soil erosion data from field observation and survey monitoring in 191 ministerial and provincial level projects

the main characteristics of soil erosion in point engineering and line engineering were analyzed. The results showed that two type projects soil erosion in the construction period accounted for about 90% of the total soil erosion. Line engineering soil erosion intensity(200.00 t/hm2) was greater than that of point engineering(151.37 t/hm2). Line engineering and point engineering were both in intensity and above grade of soil erosion. The quantity of soil erosion and the area in construction period of two type projects had a positive linear correlation(Rpoint2=0.9318

Rline2=0.9439)

soil erosion modulus had a positive correlation with per unit area cut-fill volumes in both type projects(Rpoint2=0.9595

Rline2=0.9324) after the disturbance.
