| 摘 要： | 为掌握福建省境内个22重点县水土流失地理国情现状,利用高分辨率资源三号遥感卫星影像数据进行监测分析。以土壤侵蚀分类分级标准SL190-2007为依据,通过土地利用、植被覆盖度以及坡度等水土流失影响因子的信息提取,基于GIS软件平台上,建立符合福建省水土流失地理国情的遥感监测信息提取模型。经GPS进行野外调查、验证和修改,最终完成区域水土流失图斑的提取和建库工作,为科学规划与治理及其成效分析等提供科学依据。

| Abstract: | In this paper, remote sensing image data from the high resolution ZY-3 satellite was used to monitor the current status of geographical conditions of soil erosion in 22 key counties in Fujian Province. In accordance with the standards for classification and gradation of soil erosion （SL190-2007）, information related to the factors influencing soil erosion such as land utilization, vegetation fraction and slope was extracted. On the basis of GIS software platform, a model of extraction of remote sensing monitoring information in line with the geographical conditions of soil erosion in Fujian Province was set up. After field survey, verification and modification by GPS, extraction of graph spots of the regional soil erosion and database building were finalized, providing scientific basis for scientific planning, control and related effect analysis. |
