The Discussion on Related Technical Issues of Fast Soil Erosion Remote Sensing Investigation

The article reviews more than 20 years out of 80 years of application and research work of remote sensing technology (RS), geographic information system (GIS) and global positioning system on soil erosion, and briefly introduces and comments on the technical approaches during the process of erosion investigation at different stages. It aims at making soil conservation monitoring workers understand “3S” application in soil erosion investigation process, and have a clear direction for future application study. The application of RS, GIS and GPS to soil erosion fast investigation is a beneficial attempt for the applied of Hi tech to production reality, and also is a frontier for the applied study of “3S” in water and soil conservation. Soil erosion investigation is a quite complicated task. This article, based on the experience of summary on erosion remote sensing investigation at different periods of time, aiming at the existing technical problems in the third remote sensing investigation on soil erosion, carries out an analysis and puts forward corresponding suggestions so as to consult with colleagues and to provide a reference for decision making.
