摘要:
将地理信息系统（GIS）与通用土壤流失方程 （USLE）相结合对云南新平大红山铁矿区进行土壤侵蚀量的预测和估算。结果表明：全区土壤流失面积为5.54 km2，占矿区总面积的65.17%，年土壤流失量为4.855万t。矿区50 a之后，土壤流失面积变化不大，年流失量下降为2.736万t，减少了43.65%。完成土地生物复垦后的土壤流失变化趋势是强度及其以上级别的土壤侵蚀量降低，中度及其以下的侵蚀量增加。
Abstract:
Soil loss was predicted and risk areas of soil erosion were identified in Dahongshan Iron Mine at Xinping of Yunnan province by means of combinin geographical information system (GIS) and universal soil loss equation (USLE). The results showed that the area of regional soil erosion was predicted to be 5.54 km2, which was 65.17% of the studied area. The annual soil loss is 4.855×104 t. And the erosion area will not change too much in 50 years, but annual soil loss amount will decline to 2.736×104 t, at a reducing rate of 43.65%. The change trend of accomplished vegetation rehabilitation is that the erosion loss amount of highly eroded area will reduce. And the erosion loss amount of low-grade erosion area will increase.
