Abstract: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.
