| 摘 要： | 水土流失遥感调查具有宏观、快速、效率高的优点,可以实现水土流失时空动态监测;侵蚀137Cs核素示踪技术能够提供独立的土壤侵蚀与堆积数据以及空间分布的信息,与其它方法相比,不仅具有无时空限制、操作简便快捷的优点,而且可提供上世纪60年代以来的多空间尺度(测点到流域)年均净侵蚀量。核素示踪与遥感解译的结合,可实现水土流失评价的宏观与微观、点与面、估算与实测的结合,大大地提高水土流失评价时空分辨率和精准度。文章以锦屏二级水电站工程建设区域为例,将137Cs侵蚀示踪技术和水土流失遥感调查方法相结合,基于GIS技术,对区域内水土流失现状进行了评价。 |

| Abstract: | The remote sensing of soil erosion has macroscopics, fast advantage with high efficiency, can realize soil erosion dynamically monitoring in space-time; Corrode 137Cs nuclide tracing technology can offer the independent soil erosion date and the information of space distribution. Compared with other methods, it not only have no space-time limiting, simple and convenient advantage, and can offer pure average annual erosion amount since the sixties of last century. The combination of remote sensing and the radionuclide tracing, can realize the combination of macroscopic and microcosmic, estimating and surveying in soil erosion, and can raise space-time resolution factor and accuracy of soil erosion appraisement. This text takes the Jinping secondary hydraulic power station as an example, combines the 137Cs tracing technology with remote sensing, base on the GIS technology, and evaluates the current situation of soil erosion in the area. |
