| 中文摘要: |
| 应用3S技术，利用修正的土壤侵蚀方程RUSLE 对2000 年、2010年石家庄地表水源保护区进行水土流失计算，依据水土流失强度分级标准对生成的土壤侵蚀图进行分等定级，分析说明2000—2010 年水土流失的变化及其原因，并分析了土地利用与水土流失的关系。结果表明：10年来，水土流失面积有所增加，增加面积0.33 km2。2000年中度以上土壤侵蚀等级到2010年均较大幅度转移至较低等级的土壤侵蚀；土壤侵蚀主要发生在建设用地和未利用地这两种土地利用类型。 |

| With the support of 3S technique, the soil erosion amount in the surface water sources protection zones of Shijiazhuang in
2000 and 2010 was calculated by using the revised universal soil loss equation (RUSLE), and a soil erosion map was drawn according to the soil erosion intensity classification criterion. Analysis the reason about the change of water and soil loss in 2000 and 2010, and calculates the transfer matrix of soil erosion degree from 2000—2010, analysis the relationship of land use and soil erosion. Based on these, the results showed that more than moderate soil erosion level in 2000 transferred to annually lower levels of soil erosion average relatively substantially in 2010. In 2010 the water and soil erosion belongs to mild erosion. Comparing with that in 2000, the water and soil loss area in 2010 increased markedly, with a increment of 0.33 km2, and the water and soil loss mainly occurred on the construction land and unused land. |
