Based on environmental economic theories and methods

we calculated the erosion-induced economic loss with different land-use structures in our study area over time and space. We also analyzed the dynamics of erosion-induced economic loss and the relationship between erosion-induced economics loss and land-use structure. The results show that the total economic loss resulted from soil erosion reached 9.82×109

9.94×109 and 8.80×109 Yuan in 1988

2000 and 2007

respectively. The loss of nutrient contributed most to the total economic loss from soil erosion

accounting for 87. 44%

88. 29% and 88. 02% in the three years

respectively. Among the different land-use types

the highest total economic loss by erosion was found in arable land. Grass land had higher economic loss per unit area than the other land use types. Meanwhile forest land was the lowest in terms of total loss and loss per unit area. The economic loss by soil erosion demonstrated spatial heterogeneity

Yunyang and Kaixian County had the highest total loss

and Changshou County had the lowest. Yunyang

Wulong and Kaixian County had the highest loss per unit area

where measures should be taken in the future to prevent soil erosion. Yiling district had the lowest loss per unit area.
