Description :
In this study, short-term gully retreat was monitored from the active gullies selected in representative black soil area, using differential global positioning system (GPS). With the support of geographic information system (GIS), multi-temporal digital elevation models (DEM) were constructed from the data collected by GPS and used for further analysis. Based on the analysis of multi-temporal DEM, the AA. discussed the erosion-deposition characteristics within gully between pre- and post-rainy season, and proposed a developing model for black soil gully area of Northeast China.
