| 摘 要： | 在分析土壤侵蚀形成的主要影响因子基础上,提出了基于栅格数据的流域土壤侵蚀量估算的指标模型.结合山西蔚汾河流域,以降雨、地形、沟谷密度、植被盖度、成土母质为主要影响因素,对流域土壤侵蚀量进行了估算和土壤侵蚀分级,并对土壤侵蚀量的空间分布进行了划分和分析.模拟计算结果与实测数据较为符合. |
| 关 键 词： | 栅格数据 土壤侵蚀量 流域 |

| Abstract: | An index model of soil erosion estimation was put forw ard based on raster data after analyzing the main influence factors in Weifenhe watershed.By taking rainfall,terrain,ravine density,vegetation coverage,and soil parent material as the main indexes,soil erosion was evaluated and classified and the spatial distribution of soil erosion was determined .The calculated results are accorded with measured data. |
| Keywords: | raster data soil erosion watershed |
