| 摘 要： | 以陕西省佳县为例,从遥感信息入手,以TM影像为主要信息源,并结合土地利用数据和DEM高程数据,探讨了如何通过遥感和GIS技术利用植被覆盖度、地形坡度、土地利用类型等因子快速、准确地提取水土流失信息。这一研究不仅能为水土流失调查、监测提供重要的信息源,而且为水土保持研究提供可靠的依据。

| Abstract: | Taking Jiaxian County,Shaanxi Province as the study sample,using TM images as the main information combined with land-use data and DEM,how to quickly and effectively extract soil erosion information using vegetation coverage,terrain slope and land-use type supported by RS and GIS was analyzed.This research could not only provide primary information source for soil erosion survey and monitoring,but also offer a reliable basis for soil and water conservation. |
