- Abstract:
-
Based on the principles and methods of environmental economics, the economic losses of soil erosion in the Yanhe River basin were estimated with ArcGIS 9.3. The results provided a basis for the green GDP accounting and ecological compensation policy for soil erosion. The total economic loss of soil erosion in the Yanhe River basin was 3.852 billion Yuan per year. And the economic loss of nutrient losses was the biggest part of the total economic loss, which accounted for 94.73% of the total. So the most direct and the most serious harm of soil erosion was the land productivity decline. The intensity of economic losses of soil erosion per unit area and soil erosion modules showed a decreasing trend from the upper reaches to the lower reaches of the Yanhe River. The land use influenced the economic loss of soil erosion obviously. The better the ecosystem service function and the vegetation coverage were, the smaller the economic loss of soil erosion was. The ratio of economic losses of soil erosion to GDP was 17.49% in the Yanhe River basin, which was much higher than that in China and Shaanxi Province, therefore, soil erosion is the big challenge for local sustainable development of the Yanhe River basin.
