中文摘要	基于通用土壤流失方程(USLE模型)和GIS空间分析技术,对安徽省大别山区土壤侵蚀量进行了估算。选取土壤养分、水分及泥沙滞留、淤积、土地废弃损失作为土壤侵蚀经济损失的指标,采用替代花费法、恢复费用法、影子工程法等方法,评估了安徽省大别山区土壤侵蚀的经济损失。结果表明,安徽省大别山区2007年平均土壤侵蚀模数为2 443.4 t/(km~2 ? a),土壤侵蚀总量为2. 29 * 10~7 t/a,其中金寨县和岳西县土壤侵蚀总量最高,分别为7.6210~6 t/a和5. 42 10~6 t/a。从空间分布上看,较强的侵蚀主要集中在西部地区,东北部以及南部地区侵蚀量相对较小;土壤侵蚀造成的总经济损失为92 052. 8万元,其中土壤养分价值损失最大,为82 557.8万元,占土壤侵蚀经济总损失的89. 7%,其次是泥沙损失,达4 734. 2万元,占经济总损失的5.1%。金寨县经济损失量最大,为37 266.3万元,占大别山区土壤侵蚀总经济损失的40.18%。其次为岳西县,约占23.54%。经济损失量最小的为舒城县和桐城市。
英文摘要	With the intensification of global climate change and human activity, soil erosion is more serious and has become one of the biggest obstacles to regional sustainable development. Based on USLE model and GIS spatial analysis technology, the quantity of soil erosion was estimated in Dabie mountain area in Anhui Province. Selecting soil nutrients, soil water, sediment retention-siltation and the deserted land loss as the index of economic losses, the economic loss of soil erosion in Dabie mountain area of Anhui Province was assessed using the methods of replacement cost, recovery cost, shadow engineering and so on. The results indicated that the modulus of the average soil erosion in Dabie mountain area in Anhui Province was 2 443. 4 t/(km~2 ? a) in 2007,and the total amount of soil erosion was 2. 29 X 10~7 t/a. The highest soil erosion were Jinzhai County and Yuexi County, having 7. 62 * 10~6 t/a and 5. 42 * 10~6 t/a, respectively. Seeing from the spatial distribution, the more serious soil erosion was mainly concentrated in the western region while slight soil erosion was in the northeast and southern. The total amount of economic loss of soil erosion was 920. 528 million yuan in Dabie mountain area in Anhui Province. The value of nutrition loss was the biggest with 825. 578 million yuan, accounting for 89. 7% of the total soil erosion economic loss. Sediment loss was 47. 342 million yuan, accounting for 5. 1 %. Economic loss of Jinzhai County was the biggest with 372. 663 million yuan, having 40. 18% of the total economic losses. Then it was Yuexi County, accounting for 23. 54%. The smallest is Shucheng County and Tongcheng City.
