| 摘 要： | 以大兴安岭地区为研究区,应用"北京一号"卫星数据与同期TM数据进行交叉辐射定标,计算大兴安岭地区植被覆盖度,建立大兴安岭地区土壤侵蚀空间信息数据库。以修正后的通用土壤流失方程(RUSLE)为理论基础,结合地面调查,建立土壤侵蚀知识库,通过构建空间信息与知识库耦合的土壤侵蚀监测方法,对大兴安岭地区的土壤侵蚀强度进行分级。结果检验表明,该方法具有较高的可靠性,"北京一号"能够满足中等分辨率的土壤侵蚀动态监测要求,取得的"北京一号"卫星影像定标参数具有一定的参考价值。 |
| 关 键 词： | 北京一号 辐射定标 土壤侵蚀 通用土壤流失方程 动态监测 |

| Abstract: | We do the cross radiation correction with the RS data of BJ-1 and TM data at the corresponding period,and calculate the vegetation coverage degree in the area of Da Hingganling Mts,establish the soil erosion spatial information database of this area.Based on the RUSLE theoretically,with the ground investigation,we established soil erosion repository,construct the soil erosion monitoring method coupling the spatial information and repository,grading the intensity of soil erosion in Da Hingganling Mts.The tes... |
