Abstract:The topic of rapid survey of regional soil erosion has been identified based on the analysis of sciences of soil erosion, spatial information technologies and the demand of soil conservation. The necessary and possibility of the survey have been analyzed focussing on the processes, the spatial characters of regional soil erosion and the theory and techniques of spatial informatics. Some important issues, including the classification and regionalization, the parameterization of the evaluation, the modelling of the erosion and the database building of the evaluation, and so on, have been discussed.
Keywords:soil erosion  soil conservation  remote sensing survey  rapid survey
